Photographic products for use in a color

Diffusion Transfer Processes This invention relates to photographic printing Products for use in a color diffusion transfer process, it relates to especially color diffusion transfer photographic products having a wider Treatment and development temperature latitude, which during their treatment or Development can provide dye images quickly.

There are already various types of color diffusion transfer photographic products known. In the field of color diffusion transfer processes, it is known that the dye images obtained depend to a considerable extent on the temperature used for their development and, accordingly, their image quality changes. For example, photographic color diffusion transfer products exhibit (hereinafter referred to simply as "photographic products") of certain types sometimes a low degree of whiteness of the light areas of the dye images obtained on if these images have a high minimum density as well as a high maximum density exhibit when these products are treated at relatively higher temperatures respectively If, on the other hand, these products are developed at relatively lower temperatures are treated or developed, only those images can be obtained that have a low maximum density and a low minimum density.

It is known in the field of photography that in general the process of developing silver halide in light-sensitive photographic Silver halide materials and related processes by the Temperature applied to processing or processing of photographic materials can be greatly influenced0 Therefore, in ordinary photography, i.e., in the so-called conventional photography, the development process carried out, while the treatment or

The development of the vaginal nerve is kept within a narrow range, so that favorable images can always be obtained.

In the form diffusion transfer method, however, it is extremely difficult to the temperature used in the development process is always within a narrow range Area, as the development process is in most cases within a camera immediately after the exposure is performed. That is, the above Even then, the photographic products mentioned must always be advantageous and stable Dye images provide when the temperature of the developing process is high or is low and photographic products that meet the above requirements, are considered to have a wider treatment or development temperature latitude or as such with an improved treatment or. Development temperature latitude designated. On the other hand, in the color diffusion transfer method, one more must Further Condition must be met. That is, the ones that can be used for this Products have to meet the demands of the photographer and the educated Want to view dye images as soon as possible after exposure.

In the case of photographic products for use in the Instant photography, as mentioned above, it is therefore particularly necessary that the products have a sufficiently high photographic sensitivity and favorable dye images having a high maximum density and a low one provide minimal density, which also have a suitable gradation and also a vivid description of minute details of the photographed objects give. Another important point in these photographic products is also that the images formed thereon as soon as possible after the end of the exposure can be considered, apart from the fact that the products have a broad Must have treatment or development temperature latitude, as explained above, The ability to take a photographic image within a short time after To be able to look at photography is hereinafter referred to as the speed of photography Material designated.

It is therefore an object of the present invention to provide photographic To create products that meet the various conditions mentioned above, as required by the color diffusion transfer method. Object of the invention it is in particular to provide photographic products that are in the Are able to provide advantageous dye images that are always stable, independently on the temperature that was used when the Development process The aim of the invention is also to provide photographic products, which provide dye images quickly and within a short period of time after Photographing can produce beneficial dye images.

Finally, the aim of the invention is to produce photographic products To provide stable and beneficial dye images that give can be viewed within a short period of time after exposure, regardless of the temperature used during treatment or development when the photographic products are in the color diffusion transfer process can be used in which a non-diffusible dye image forming Substance is used, whereby this substance is able to react by reaction (for example Redox reaction, coupling reaction or the like.) Under alkaline conditions with a Oxidation product of a 51% halogenide developer compound a diffusible To release dye or a precursor thereof There are already some methods to widen the treatment or. Development temperature range, i.e. for Achievement of one of the above-mentioned objects according to the invention, known0 For example in a process described in US Pat. No. 3,846,128, a photosensitive Silver halide emulsion layer for imaging in combination with a Layer used, which is a photosensitive silver halide emulsion with a opposite effect as the first-mentioned emulsion layer and a compound which contains a diffusible development inhibitor as a result of development can release when the image recording -Silver halide emulsion is a direct positive silver halide emulsion, so it is in this case for the opposite effect, a negative-type emulsion. In this procedure is only the broadening of the treatment or development temperature range possible when the imaging emulsion and the emulsion with the opposite Effect to this individually the same sensitivity in a specific spectral range and if these emulsions are also related in terms of their properties are essentially identical to the dependence on the development temperature. In the above method, however, it is necessary for image recording in addition to a photosensitive silver halide emulsion layer, one more to use another emulsion layer.

Generally it is from the standpoint of coating processes Do not threaten light-sensitive materials, even ordinary ones light-sensitive materials for so-called conventional photography, with to provide one or more additional layers because of the associated Loss of speed or delay in development of the lower layer or shifts or other reasons. Also from the point of view of diffusion one Silver halide developer compound and the diffusion path of a diffusible Dye or a precursor thereof, it is clear that any additional No formation of one or more layers in the photosensitive materials is preferred.

To now the processing or development temperature range of the photographic Widening the product according to the method described above is a must Emulsion with an opposite Effect on an imaging emulsion, the first-mentioned emulsion being used in combination with the last-mentioned will have a sensitivity identical to that of the image recording layer is, and moreover, the first-mentioned layer must have the same property with respect to the dependence on the developing temperature, like the latter Have emulsion. As research has shown, it is extreme difficult to find two types of emulsions with opposing functions to select those that meet these strict conditions, such as those mentioned above Procedures are called for, and to achieve this goal u have a large number of Emulsions are available.

in the process described in U.S. Patent 3,575,699 the use of a compound that is subject to hydrolysis under alkaline conditions can become an antifoggant, the hydrolysis rate resp. rate of this compound depends on the temperature used in the hydrolysis.

In US Pat. No. 4,009,029 a method is described with which prevents the decrease of the maximum density at increased temperatures should by using a proprietary development inhibitor in the diffusion transfer process, in which mainly an oxychromic developer or a dye releasing agent An agent is used that produces a dye in the unexposed area during hydrolysis releases, but does not release any dye in the exposed area. The one above These oxychromic developers include, for example, such compounds as they in U.S. Patent 3,880,658 and the dye releasing agent Agent includes, for example, such compounds as are disclosed in the US patent 3,980,479 are specified. The purpose of using this development inhibitor was to improve the maximum density in the color diffusion transfer process, in which mainly negative-type silver halide emulsions are used, however, efforts are being made to provide such an improvement as the Broadening of the treatment or development temperature range, also in that Color diffusion transfer process is enabled in the silver halide emulsions positive type and dye releasing redox compounds can be used. The dye-releasing redox compounds used here are these are connections that are explained in more detail below.

In multicolor silver halide photographic light-sensitive materials On the other hand, it is known that effective amounts of nondiffusible in interlayers Removal agents for an oxidized silver halide developing agent are incorporated must be in order to achieve an advantageous color separation. The above Non-diffusible removal agents or cleaning agents (scavengers) for a oxidized silver halide developing agent is hereinafter abbreviated to "SC".

It is also known to achieve a greatly improved minimum Dense the SC in the above intermediate layers, in silver halide emulsion layers or to be used in layers that form a dye image contain substances, which are used in combination with these emulsion layers.

The above mentioned SC are known compounds, how e.g., hydroquinone type compounds as in Japanese Patent Publication No. 12 250/1976, described in U.S. Patents 2,728,659 and 2,816,028, and, for example, so-called couplers, which react with the oxidized products of developer compounds from the primary aromatic amine type can enter into a coupling reaction, such as in U.S. Patent 2,474,293.

However, any connections can be used as the SC, see above long they react with oxidized silver halide developing compounds and thereby a reaction of the oxidized agent with a dye image-forming substance impede. From the standpoint of effectively utilizing the silver halide developing agent or from the standpoint of diminishing a loss in developability of the lower ones Layer, based on the upper layers, is considered to be the Reaction of these compounds with the oxidized silver halide developing agent, as mentioned above, to a reaction which is a reverse transformation of the oxidized agent into its original reducing form, i.e. such a reaction is usually known as regeneration of the silver halide developing agent. If there is a silver halide developing agent in a black and white developer, such as hydroquinone, phenidone or catechol, is used, including the Use of a color developer compound from the so-called primary aromatic Amine-type, such as p-phenylenediamine, SC is useful as a compound that has an oxidation-reduction reaction enters into with the oxidized silver halide developing compound and thereby the oxidized Agent reverted back to its original reducing form.

In the multicolor diffusion transfer process in which a non-diffusible Dye image forming substances are used, the one coupling reaction or an oxidation-reduction reaction with an oxidized silver halide developing agent enter with the release of diffusible dyes or precursors thereof, it is important to use the above mentioned SC and this can be beneficial Color separation can be achieved. Using the method described above to improve the treatment or development temperature range in combination with the method described above, advantageous photographic Multicolor images with a wider treatment or development temperature range and excellent color separation can be obtained.

Corresponding studies have shown, however, that also in the method described above still some technical problems remain unsolved. One of the problems is the speed of dye imaging. How on stated above is the speed in the color diffusion transfer process according to the invention, one of the most serious concerns of photographers.

Another unsolved problem is the low efficiency of the Exploitation of the silver. That is, it was found that the dye image density is small compared to the amount of an oxidized silver halide developing agent, that is obtained in the silver halide development, or that by the developer compound developed amount of silver. To achieve sufficient dye image density so far there was no other option than the amount of what is commonly used To increase silver halide even further.

After extensive investigations and research into the various problems, it has now been found that these problems can be solved by incorporating in a photographic color diffusion transfer product which contains or consists of a photosensitive element having a support and at least one photosensitive silver halide emulsion layer and one non-diffusible Dye image-forming substance represented by general formula (I), (II) or (III) shown below, which is associated therewith and is capable of reacting with an oxidized silver halide developing agent under alkaline conditions to liberate a diffusible dye or a precursor thereof, and an image-receiving layer, which can fix the diffusible dye or its precursor thereon, incorporates into the photosensitive element a compound which is nondiffusible upon hydrolysis under alkaline conditions capable of removing the oxidized silver halide developing agent: DYE - LINK - COUP - BALL (I) BALL - LINK - (COUP) '(11) where: DYE is a diffusible dye residue or a precursor thereof, LINK is a divalent connecting group selected from -O-, -S-, -N = N- and -SO2NH- (with the proviso that the nitrogen atom at COUP or (COUP ) 'is bonded), COUP a coupler group which is selected from couplers of the 5-pyrazolone, phenol, naphthol, open-chain ketomethylene, indanone and cyclopentanone type, (COUP)' a coupler group which is selected from couplers of the 5-pyrazolone, phenol, naphthol and open-chain ketomethylene type (with the proviso that COUP and (COUP) 'are individually bonded to LINK in the coupling position), BALL is a photographically inert Bollast group with such a molecular size and / or steric configuration that it can make the substance of the general formula (I), (II) or (III) non-diffusible under alkaline conditions, (LINK) 'a divalent connecting group selected from -0-, -S- , -SO2- and -SO2NH- is bound to) and be that the nitrogen atom Z, the non-metal atoms which are required to complete a 5 or 6-membered ring together with the carbon atom bonded to (LINK) ', which in the oxidation-reduction reaction with the oxidized syllable F-halide developing agent alkaline conditions can cleave the bond with (LINK) '.

The above-mentioned compound of the present invention which is involved in hydrolysis a non-diffusible removal agent for under alkaline conditions an oxidized silver halide developing agent is described below abbreviated to "SCP" for simplicity.

The demand for compounds used as SCP in accordance with the invention can be satisfied using various test methods. For example, a solution of SCP in a water-miscible organic Solvent such as dioxane with an aqueous alkali solution to a pH of 9 or higher, and the resulting solution is then observed to be a Determine the change in the light absorption spectrum so as to judge whether the SCP during hydrolysis to S (; can be reconverted or not.

According to the invention, any compounds can be used as SCP, see above as long as these are those that have been made by any test procedure, including of the procedure described above have been tested to determine whether the compounds that were essentially inert as SC prior to hydrolysis, after the hydrolysis in contact with an alkali solution become active as SC.

The SCP according to the invention is preferably one Connection, which occurs after a limited time has elapsed after their contact can be hydrolyzed with an alkali solution. The above limited time, which is considered suitable for this purpose can, depending on the for Dispersion of the SCP method used and depending on the silver halide emulsions and treatment or development compositions, the at the Manufacture of photographic products and their treatment or development used to vary stork.

However, it has been found that better results can be obtained by using SCP with a half-life of about 10 seconds up to about 7 minutes, preferably from 20 seconds to 3.5 minutes, for example after can be determined using the following procedure: a mixture of 7 parts by volume of a Solution of the SCP in dioxane and 3 parts by volume of a buffer solution with a pH value of 12.5 is rapidly stirred and the mixture is checked using a fast scanning spectrophotometer observed to determine a change in spectrum, taking the half-life the hydrolysis reaction of the SCP at room temperature.

On the other hand, with regard to the fact that the How the spectrum changes over time depending on the type of SCP varies and it is difficult to precisely define the half-life in which the above procedure the values: for the half-life for reasons of expediency the time required within which the residual SCP concentration is half reached their original concentration. The procedure described above to determine the half-life explained above is only one in every respect Example and the invention is therefore based on the above values for the half-life in no way $ restricted.

In this context, it should be noted that as an inventive SCP is a compound of the formula S¹-A¹ or A²-S²-A³ is preferred. In these formulas S1 and S2 individually each represent a non-diffusible remover residue dar and A¹, A2 and A3 are each directly to the oxygen or Nitrogen atom of the remover residue bonded, being the remover residue deactivate and a non-diffusible removal agent for an oxidized Silver halide developing agent on hydrolysis under alkaline conditions can form.

A wide variety of methods for incorporation can be used according to the invention can be applied by SCP without affecting the methods explained above are limited.

When two or more types of SCP are used in combination, each SCP can be dispersed separately or it can be mixed with another SCP are before or during or after dispersing.

The photosensitive member of the present invention has at least one light-sensitive silver halide emulsion layer applied to a support and the above-mentioned DFM as well as that with the light-sensitive silver halide emulsion layer associated SCP. In the light-sensitive silver halide emulsion used in the present invention it is a lloidal dispersion that contains, for example, silver chloride, Silver bromide, silver chlorobromide, silver iodobromide, silver chlorifiodobromide or contains a mixture of these. Those in the above silver halide emulsions silver halide particles used are advantageously useful when they have an average particle diameter within the range of about 0.1 to about 2 microns, although the particles are also can deal with a fine or a coarse grain. The silver halide emulsions can be prepared by any known method, e.g. a process for the production of single jet emulsions, Lippmann ewulsions or emulsions ripened with thiocyanate or thioether. You can also use emulsions are used, the silver halide particles having a considerable surface sensitivity and emulsions can be used become the silver halide particles contained with considerable sensitivity inside the particles.

According to the invention, both emulsions of the negative type and direct positive emulsions can be used. In the case of the silver halide emulsions The hydrophilic binders used are preferably gelatin.

The amount of the above in the light-sensitive silver halide emulsion associated DFM can be varied within a wide range depending on on the type of DFM and the desired effect expected from its use is, for example, the molar ratio is between that in the silver halide emulsion layer present silver and the DFM about 50 to about 0.5, preferably about 30 to about 5. There can also be two or more DFM connections in association with a light sensitive silver halide emulsion can be used, as in Japanese Patent Application No.

114 943/1977 described. In this case the proportion is one of the DFM compounds, based on the whole, usually 15 to 85 mol%, preferably 20 to 80 mol%, especially 30 to 80 mol%. When incorporating the DFM connection similar processes as in the case of SCP, as indicated above, can be applied. When incorporating the DFM connection in the photosensitive element, hydrophilic binders can be used, such as those used in the silver halide emulsions as noted above. The DFM compound associated with the silver halide emulsion layer can be incorporated into the Silver halide emulsion layer and / or in at least one other Layer incorporated as the silver halide emulsion layer, preferably a layer which are adjacent (contiguous) and opposite to that of the silver halide emulsion layer is arranged during exposure. When two or more DFM connections are in association can be used with a photosensitive silver halide layer Compounds are incorporated into one or more layers.

As stated above, this can be done with the silver halide emulsion layer associated DFM compound when reacted with an oxidized silver halide developing agent a diffusible dye or precursor under alkaline conditions release of it according to the imagewise exposure. If the according to the invention DFM compound in association with a silver halide emulsion layer of the @egative type is used without a special Umkahr ancestor, it ha @ dels with that a dye image obtained from an image-receiving layer and a negative image. One must therefore use the inverse method in order to obtain a positive on the image receiving layer Dye image and a positive diffusion transfer dye image is obtained by using inverse methods of various types.

For example, methods can be used in which a Direct positive type silver halide emulsion layer is used, as in US Pat U.S. Patents 3,227,553, 2,592,250, 2,005,837, 3,367,778, and 3,761,276, in British Patent 1,011,062, Japanese Patent Publication 17 184/1966 and in Japanese Patent Application Laid-Open No. 8 524/1975, or it can Processes are applied in which a physical development is applied is as described in British Patent Publication 904 364 or Japanese Offenlegungsschrift 325/1972, or a method can be used in which a a dye image-forming substance is incorporated in a fogged emulsion layer and a negative type silver halide emulsion layer as an adjacent layer is used, the layer containing a compound that is active in the implementation with an oxidized silver halide developing agent, a development inhibitor can release, as in Japanese Patent Publication 21 778/1968 and in Describe U.S. Patents 3,227,554 and 3,632,345.

Positive dye images can be produced in the manner described above can be obtained by using various methods, but is preferred a method advantageously applicable to direct positive silver halide emulsions Type to be used. On direct positive type emulsions used in this process can be used include e.g. B. those created by exposure to light or by a chemical treatment which has been carried out in advance, easily and which, when subjected to imagewise exposure, become non-developable according to the imagewise exposure. Also can other direct positive type silver halide emulsions may be used, mainly are sensitive inside the silver halide grains. According to the invention, photosensitive Silver halide emulsions of the last-mentioned direct positive type, they in of the US patent 2,761,276 are preferably used.

When direct positive silver halide emulsions of the latter Type exposed imagewise to light arise mainly in the interior of the Silver halide particles could become images and the positive silver images formed during surface development under fogging conditions. the Development under such obfuscation conditions can be accomplished using various Methods are carried out. It can be a so-called air fogging developer be used, as for example in German patent specification 850 383 or in U.S. Patent 2,497,875.

Alternatively, the entire surface of the emulsions can be used at one time subject to the development of an exposure, as in the German latent 854,888, US Pat. No. 2,592,298 and British Patents 1,150,553, 1,195,838 and 1,187,029. In addition, development in Presence of fogging agents can be carried out. To those in this case Usable fogging agents include hydrazine-type or N-substituted compounds quaternary cycloammonium salts, these compounds and salts either individually or can be used in combination. Preferred examples of these compounds and salts are 1- [4- (2-formylhydrazino) phenyl] -3-phenylthiourea and β-acetylphenylhydrazine in combination with t-butylaminoborane. The amount of the fogging agent used They can vary widely depending on the purpose for which the agent is used However, is generally 0.1 to 2.0 g per liter of an alkaline treatment or developing composition when they are in the alkaline processing or developing composition added and it is 0.001 to 0.2 g per m 2 when it is the photosensitive member is set.

According to the present invention, the above-mentioned silver halide emulsions can be used negative-type or various reversal methods can be used and by any Combination of DFM connections with it gives negative results on the image receiving layer or positive dye images. In this case the DFM connection is preferred incorporated in a layer that was exposed to light on the silver halide emulsion layer is arranged opposite, so that the sensitivity of the Silberhlaogenidemuldion is not decreased in the silver halide emulsion layer. The DFM connections, the Lauco type dyes contain the shift type dyes to one shorter wavelengths or those that did not contain any dye structure at the time of exposure However, they do not lower the sensitivity of the emulsion and they can therefore, or they can be incorporated into the silver halide emulsion layer be incorporated into a layer that is relative in the direction of exposure is arranged to the silver halide emulsion layer. Using a or two or more combination units of the silver halide emulsion layer and DFM can have monochromatic or multicolor dye images on the image-receiving layer can be obtained.

The photosensitive wavelength range of the photosensitive silver halide emulsion layer can be the same or it can be different from that Absorption wavelength range one on the image receiving layer by a diffusible dye or a Precursor thereof that releases from the DFM associated with the emulsion layer formed dye image and this association of the silver halide emulsion layer with the DFM can be used in so-called pseudo-color photography. if the DFM compounds are used in ordinary multicolor photography, becomes a yellow DFM in association with a blue-sensitive emulsion layer A purple DFM is used with a green sensitive emulsion layer associated and a cyan DFM is associated with a red sensitive emulsion layer associated.

In addition, two or more combination units can be made from the silver halide emulsion and DFM connections are used. are shaped by applying these units one shift, for example using the mixed packet method.

When the present invention is applied to multicolor photography is, is in the photosensitive element, preferably between the associations, an intermediate layer is expediently used. The intermediate layer prevents an unwanted one Interaction between the association of emulsion layers and DFM compounds occurs, the emulsion layers having different color sensitivities, and at the same time this increases the diffusivity of a diffusible dye or a precursor thereof or an alkaline processing composition controlled. A useful intermediate layer consists of gelatin, calcium alginate, Vinyl acetate / crotonic acid copoly The carriers, on the different Layers are applied, which build up the photosensitive element exist preferably of planar materials so that they can be used during the treatment or development stages no pronounced dimensional change due to the treatment or. Development compositions are subject. The carrier, which must be transparent or opaque (opaque) is appropriately selected depending on various conditions such. B. the layer arrangement of the photosensitive element and the image receiving layer, the direction of exposure to light or the treatment or development involved must be done in light or dark places. When using a transparent And when the treatment or development is carried out in a bright place is appropriately colored to such an extent that the light transmission in the surface direction can be prevented without hindrance the exposure to light and observation of the images produced so that the passage of light through the edge of the support towards those on the surface of the Support applied silver halide emulsion layer is prevented.

After the imagewise exposure, the above-mentioned becomes light sensitive Element treated with an alkaline treatment or developer composition or developed, with a diffusible dye in the image receiving layer diffused, which rests on the photosensitive element, and then the diffusible dye fixed to the image receiving layer to form a Dye image on it. the mer, @sopropylcellulose, hydroxypropylmethylcellulose, Polyvinylamides, a polyvinylamide graft copolymer or a system of one Latex liquid and impregnating agents. The intermediate layer can also be used as a filter layer be used by incorporating colloidal silver, and filter dyes like in the same. As the outermost layer that is on top of the layers on a support is applied, a protective layer can be used and to produce the Protective layer, materials similar to those used for the intermediate layer can be used will.

When applying the above-mentioned layers to the Toger, the coating compositions of the same expediently using coating auxiliaries, as commonly used in the field of photography to facilitate the coating process and in these compositions such thickeners can expediently be incorporated.

The above-mentioned coating compositions or coating masses are preferably used together with other coating compositions according to the slide-hopper coating process applied, although various other coating processes are also used can be, such as B. the curtain coating process, the dip coating process, the roll coating process and the air knife coating process including of course the slide hopper coating process.

The image receiving layer preferably contains a mordant.

In the case of the mordant suitable for the image receiving layer, it can be any of the mordants that are a preferred mordant Effect on diffusible dyes or precursors thereof, which have by diffusion be transferred into the image receiving layer. Suitable mordants are, for. B. poly-4-vinylpyridine, Poly-4-vin; yl-N-benzylpyridinium-p-toluene sulfonate, cetyltrimethylammonium bromide, wld Compounds as described in Japanese Patent Application No. 66,494/1977 are.

The above pickling agents are used in various binders, z. B. in ordinary gelatin, polyvinyl alcohol, polyvinyl pyrrolidone and completely or partially hydrolyzed cellulose esters are used. The image receiving layer but can also consist of binders alone, which have a caustic effect, such as e.g. poly-N-methyl-2-vinylpyridine, N-methoxymethyl-polu-hexylmethylene adipamide, Copolymers of vinyl alcohol and N-vinylpyrrolidone or polymer mixtures, in part hydrolyzed polyvinyl acetate, acetyl cellulose, gelatin and polyvinyl alcohol. The amount of the mordant contained in the image-receiving layer is preferable 10 to 100% by weight. In a special case, the pickling agent can also be used in an alkaline treatment or

Developer composition are incorporated. The image receiving layer may also contain various additives commonly used in the art used in photography; become, such as B. ultraviolet absorbers, fluorescent brighteners and the same.

If the diffusible diffusible which diffuses into the image receiving layer Dye not a dye as indicated above, but a precursor of such diffusible dye, for example a leuco dye, is in the image-receiving layer expediently incorporated an agent which contains the precursor can be converted into the corresponding dye, such as. 3 ',, oxidizing agents, color developing agents or diazonium compounds. The above-mentioned image receiving layer can at the time the treatment or development with the alkaline treatment or developer composition rest on the photosensitive element and this layer and the element can be separated from each other prior to treatment or development or they can to be united in one body. After treatment or development the photosensitive member and the image-receiving layer can be made into one body be combined with each other or they can be separated from each other The image-receiving layer can in the manner described in U.S. Patents 3,594,165 and 3,689,262 be generated on the carrier of the photosensitive element or it can be on another carrier, such as in the US patents 3,415,646 to 3,315,646, but in this case they are photosensitive Element and the image receiving layer separated from each other (removed from each other), or the photosensitive element and the image-receiving layer are usually generated on separate supports when after treatment or development from each other separated (deducted).

After dye imaging by applying the alkaline Treatment or developer composition is essentially complete the pH values within the photosensitive element and the image-receiving layer preferably reduced to a value in the vicinity of the neutral point in order to thereby to increase the stability of the dye image produced and at the same time a further To suspend imaging as the essentially completed imaging to a discoloration or staining in the generated image as a result of a high pH value occurs to prevent. To achieve this goal is preferred uses a neutralizing agent to lower the pH within the system. In particular, a neutralization layer that contains a neutralization agent used as a neutralizer in the photographic product. As a neutralizing agent preferably usable materials are film-forming polymer acids with at least a carboxyl group, sulfo group or a group which, upon hydrolysis, is a Forms carboxyl group. The thickness of the neutralization layer cannot be definite has been set, but it is generally expediently within the range from 5 to 30 microns as the thickness depends on the composition of the used alkaline treatment or developer composition and in the neutralization layer incorporated materials may vary.

In combination with the neutralization layer mentioned above can be a timer layer (one that controls the rate of neutralization Layer) can be provided in order to control a drop in the pH value. This timer shift can cause the pH to drop postpone until and after the desired Development and transfer can be achieved. That is, the timer layer serves to prevent an undesirable decrease in the density of the transferred dye image, which is due to a rapid drop in pH within the system is to prevent being passed through the neutralization layer before the termination of the Development of the silver halide and the formation of that transferred by diffusion Dye image is caused. The neutralization layer and the timer layer can be applied to the above-mentioned support of the photosensitive element or together with the image-receiving layer on a support other than the support of the light-sensitive element or they can be applied to a treatment or development sheet, as explained in more detail below, are applied.

The photographic product of the present invention can be used in various There are forms as they are already known, for example those like them in U.S. Patents 3,415,644, 3,415,645, 3,415,646, 3,473,925, 3,573,042, 3,573,043, 3,594,164, 3,594,165, 3,615,421, 3,576,626, 3,658,524, 3,635,707, 3,672 890, 3,730,718, 3,701,656 and 3,689,262 in Japanese Patent Laid-Open 6 337/1975 and in Belgian patents 757 959 and 757 960 are.

After the diffusion transfer of a dye image has ended the image-receiving layer accordingly remains in the light-sensitive element the diffusion transferred dye image, a silver image and a through the Dye or a precursor thereof. It is also possible to use a dye image to obtain the reverse image of the dye image formed on the image-receiving layer by removing the residual silver and silver halide by treatment with a bleach and fix bath or with a bleach-fix bath and if necessary by performing a treatment to convert the dye precursor into the appropriate Overfold dye.

By using the photographic products of the present invention it has become possible for the photographer to be at an early stage after the Photographing a favorable multicolor image with excellent color separation, with a sufficiently high maximum density and a sufficiently low minimum Can consider density regardless of the treatment or development temperature.

The function and working mechanism of SCP, which, as assumed is due to many effects that are obtained when using the inventive photographic products obtained have not yet been fully clarified. However, it is believed that the effects of the photographic products of the present invention due in part to the fact that the SCP has poor responsiveness to an oxidized silver halide developing agent until the SCP is hydrolyzed under alkaline conditions, but that the SCP after the Contact with an alkaline treatment or Developer composition after After a certain period of time it is hydrolyzed and then its reactivity is activated with the oxidized developer compound and that in addition to these properties of the SCP the length of time from its contact with the alkaline treatment resp. Developer composition up to its hydrolysis from the temperature at the time the treatment or development depends, the period of time being the shorter, the more higher is the treatment or development temperature, and conversely, the Time span around so longer, the lower the treatment or Development temperature is. In addition, the invention has other specific advantages observed. It is known that SC originally represented an active connection and that therefore the durability of light sensitive silver halide emulsions is adversely affected by SC of various kinds. For example, if photosensitive elements that contain certain types of SC for a long time Period of time so there are some elements that have a photographic loss Have sensitivity, some of which have a decrease in maximum density of the dye images produced and some of them an increase in the minimum density of the generated dye images. The inventive use of SCP has now surprisingly been found that the above-mentioned disadvantages of the SC are overcome without the inherent effectiveness of the SC being lost.

Another practical advantage of the invention is the improvement the dispersion stability of SO. Usually SO is in the form of a dispersion, for example the so-called protective dispersion used in the high-boiling solvent be used. However, it is known that some of these SC dispersions have a have poor dispersion stability and that crystals separate out when the dispersions themselves or coatings made therefrom for a long period of time be stored. According to the invention it has now been found that this problem as well above can be easily solved.

Another practical advantage of the present invention is based on improving the gradation of the dye images produced. The gradation an image is among the various photographic properties even then of importance if no further emphasis is placed on it. Even in photographic In color diffusion transfer images, it is desirable that the images be excellent Wisely reproduce fine and tiny parts of the toned or heavily exposed areas.

In the usual color diffusion transfer method, there have been many cases found where the above SC in the photosensitive elements was used, and the consequence of this was that the elements were the very fine parts could only inadequately reproduce in the heavily exposed areas because of the low gradation in the heavily exposed areas (light areas of the image). It has now surprisingly been found that in the photographic products according to the invention this gradation problem has been successfully solved to achieve the desired one beneficial results.

While the invention has been described in detail above, it has been however, we have found many additional improvements in color diffusion transfer photographic products can be achieved. It goes without saying that these technical improvements also fall within the scope of the present invention.

The excellent properties exhibited by the photographic Have products are explained in more detail in the following examples, unless However, it should be noted that the invention is based on this Examples is not restricted.
