Field of the Invention The present invention relates to a multilayer color photographic material showing improved color reproducibilty and providing color images having uniform quality by color development. In particular, the invention relates to a multilayer color photographic material which is not developed unevenly in high temperature development.

2. Description of the Prior Art A multilayer color photographic material usually has on a support a blue-sensitive emulsion layer which contains a yellow coupler and is mainly sensitive to blue light (BL), a green-sensitive emulsion layer which contains a magenta coupler and is mainly sensitive to green light (GL), a red-sensitive emulsion layer which contains a cyan coupler and is mainly sensitive to red light (RL), intermediate layers (ML), a filter layer (FL) capable of absorbing ultraviolet light and visible light in a specific wavelength region, an antihalation layer (AHL), a protective layer (PL), and other photosensitive emulsion layers containing various couplers and having various spectral sensitivity distributions depending on the purposes.

Various attempts have been made for improving the color reproducibility of multilayer color photographic materials.

In a first attempt, an organic compund which can increase the interlayer interimage effect is applied. For instance, in such an attempt it is well known to use an organic heterocyclic compound having an oxo group or a thioxo group. Such compounds are described in, for instance, the specifications of German Ofienlegungsshriften (OLS) 2,043,943 and 2,043,944.

In a second attempt, a compound having a mercapto group or a thioether bond is used. Examples of such a compound are 2-mercaptobenzotriazole, B-hydroxyethyl isothiouronium nitrate, 2,3-dimethylthiazolium salt, l-(2-mercaptoethyl)-l,4,4-trimethyl piperidinium salt, and 2-thioxobenzotriazole. These compounds are also described in detail in the specification of, for instance, U.S. Pat. No. 3,536,487 and the specifications of U.S. Defensive Publications T909,022 and T909,023.

In a third attempt, a colored coupler is used.

In a fourth attempt, an uncolored coupler for interlayer color correction is used. Such uncolored couplers are described in U.S. Pat. No. 3,632,345 and U.S. patent application Ser. No. 467,539, filed May 6, 1974 and Ser. No. 454,525, filed Mar. 25, 1974.

In a fifth attempt, the halogen composition, in particular, the density distribution of silver iodide in a photosensitive silver halide emulsion in each emulsion layer of a multi-layer color photographic material is controlled as described in U.S. patent application Ser. No. 454,525, filed Mar. 25, 1974. The effect with the fifth attempt is, however, less than those of the above mentioned attempts.

In a sixth attempt, a hydroquinone derivative for interlayer color correction is used. These compounds are described in U.S. patent application Ser. No. 461,087, filed Apr. 15, 1974.

These attempts can improve effectively the color reproduction of multilayer color photographic materials but, on the other hand, give rise to serious defects. A first defect is with respect to the so-called interlayer interimage effect or the under-cut interimage effect, namely the effect that a development inhibitor is released from the start of the development and diffuses in the adjacent layer to inhibit the development of the adjacent layer occurs, in that the released inhibitor diffuses in a developer through the group of photosensitive emulsion layers to inhibit the development in an unnecessarily wide range, results in inducing uneven development. The latter defect also reduces the quality of the developed color images. Therefore, in order to provide improved effects so that the desired best color reproduction is obtained, the working range of the released development inhibitor must be restricted to only the range between those photosensitive emulsion layers for which an interlayer interimage effect with each other is obtained. The first defect as mentioned above tends to occur when the aforesaid first, second, third, fourth, and sixth attempts, in particular, the fourth attempt of improving thecolor reproduction of multilayer color photographic materials is applied and further this defect occurs to an even greater extent when rapid development is applied to color photographic materials at temperatures higher than about 30C. On the other hand, it is known that when the fifth attempt mentioned above is applied, the interlayer interimage effect occurs advantageously even in high temperature development.

Also, the second defect is that when the aboveindicated first, second, fourth and sixth attempts for improving the color reproduction of a multilayer color photographic material are applied, the quality of the images obtained with a developer which has been used repeatedly is greatly inferior to the quality of the images obtained with a fresh developer. On the other hand, it is known that when the fifth attempt is applied, the interlayer interimage effect occurs remarkably even in the case of using a developer which has been used repeatedly. The harmful influences on the image quality due to the development inhibitor released in a developer when the multilayer color photographic materials to which these first, second, third, fourth, and sixth attempts are applied are developed differs from the case of developing the multilayer color photo graphic materials to which the fifth attempt is applied. It is known that an iodine ion is caught almost totally by undeveloped silver halide grains by a replacement reaction and thus diffuses less in a developer.

SUMMARY OF THE INVENTION An object of this invention is to improve the defects resulting when the aforesaid first, second, third, fourth, and sixth attempts of improving the color reproduction of multilayer color photographic materials are applied.

Another object of this invention is to provide a multilayer color photographic material which shows improved color reproducibility and which has the ability to be processed using high-temperature high-speed processing at temperatures higher than 30C without uneven development resulting.

These and other objects of this invention will become apparent from the descriptions of this invention given hereinafter.

The term organic accelerator for the interlayer interimage or under-cut interimage effect as used in this invention designates an organic compound which is incorporated selectively in a specific photosensitive emulsion layer and increases the interlayer interimage effect or the under-cut interimage effect on other adjacent photosensitive emulsion layer at development and these organic compounds are described in US. Pat. No. 3,536,487; U.S. Defensive publication T909,022 and T909,023 and German Offenlegungsschriften (OLS) 2,043,943 and 2,043,944.

For instance, these organic acclerators are compounds represented by general formula (II);

R R2 (II .1

wherein X represents a sulfur atom, an oxygen atom, a selenium atom, or an =NR:, group, wherein R represents a hydrogen atom, an aliphatic group (e.g., alkyl such as methyl, hydroxyethyl, sulfopropyl, carboxyethyl, methoxyethyl, chloroethyl, benzyl, etc., or alkenyl such as allyl, etc.), an aryl group (e.g., aryl such as phenyl, hydroxyphenyl, methylphenyl, methoxyphenyl, chlorophenyl, etc.), or a heterocyclic group (e.g., pyridyl, etc.); R and R each represents a hydrogen atom, an aliphatic group (e.g., alkyl such as methyl, hydroxyethyl, sulfopropyl, carboxyethyl, methoxyethyl, chloro ethyl, benzyl, etc., or alkenyl such as allyl, etc.), or an aryl group (e.g., aryl such as phenyl, hydroxyphenyl, methylphenyl, methoxyphenyl, chlorophenyl, etc); and Q represents a non-metallic atomic group for forming a heterocyclic ring usually used as a nucleus ofa cyanine dye (e.g., 4-pyridyl, 2-quinolyl, oxazolyl, benzox azolyl, imidazolyl, benzimidazolyl, thiazolyl, benzothiazolyl, etc); or the general formula (III);

(III) wherein Q and R have the same meaning as Q and R in general formula (ll).

Further, a mercapto compound such as l-phenyl-S- mercaptotetrazole, 2 methylthio-5- mercaptothiadiazole, 2-mercapto-5- sulfobenzothiazole, l-methyl-2-mercapto-5- sulfobenzimidazole, etc., are useful.

When the development inhibiting releasable group (i.e., Z in general formula (I) in the interlayer color correction coupler is a mercapto residue, chemically the mercapto group adsorbs strongly on a photosensitive silver halide and thus the interlayer color correction effect is rather weak and the development inhibition effect in the emulsion layer occurs strongly. On the other hand, when the development inhibiting releasable group is the residue represented by general formulas (Ia), (lb) or (lc), the interlayer color correction effect appears strongly. In this case, the useful effect of the colloid layer for adsorbing the organic development inhibitor appears to a remarkable extent.

The organic accelerator for the interlayer interimage effect, in particular, the organic accelerators represented by general formulas (ll) and (Ill) show a high interlayer interimage effect or under-cut interimage effect in rapid development at temperatures higher than 30C but, on the other hand, uneven development occurs. Uneven development is prevented by the positioning of a colloid layer for adsorbing the organic development inhibitor according to the present invention. Also, the interlayer color correction effect is increased due to the use of the organic accelerator and the interlayer color correction coupler. The colloid layer for adsorbing the organic development inhibitor prevents uneven development from occurring in this case. Uneven development will be explained in detail in Example 1 stated. below.

The colloid layer for adsorbing the organic development inihibitor used in this invention is a colloid layer having the function of fixing by adsorption the development inhibitor residue released from an interlayer color correction coupler at development or the development inhibitor residue released by the development of silver halide grains from the organic accelerator for the interlayer interimage effect which has been adsorbed on the silver halide grains in a photosensitive emulsion layer, whereby the development inhibitor residue is prevented from being released in a developer. The colloid layer has also the function of adsorbing the development inhibitor residue once released in a developer, if any, namely the function of removing the development inhibitor residue from a development or appropriately controlling the diffusion of the development inhibitor residue in a developer when the development inhibitor residue is released in the developer. Therefore, it is preferable that the colloid layer of this invention be disposed on or under the photosensitive emulsion layer group, i.e., between the photosensitive layer group and the support.

The colloid layer can contain silver halide grains and further an adsorbent, such as colloidal silica, aluminum hydroxide, a colloidal metal such as colloidal silver, colloidal gold, etc. A suitable amount of the adsorbent ranges from about 0.01 to 10 g/m preferably 0.1 to 5 g/m It is preferable that the silver halide grains be fine grains so that they have a large adsorption ability and adsorption capacity and further that the amount of iodide ions in the silver halide grains be small. In particular, it is preferable that the silver halide grains be super fine grains having a mean grain size less than about 0.2 microns, e.g., about 0.005 to 0.2 microns, preferably 0.01 to 0.1 microns. A suitable amount of the silver halide grains in the colloid grains ranges from about 0.01 to 30 g/m preferably 0.1 to 5 g/m Furthermore, in order to retain the strong adsorption power in a developer, it is preferable that the silver halide grains not be developed by the developer and not be dissolved in the developer. Therefore, silver halide grains which have not been chemically matured or ripened or are silver iodobromide grains containing less than 10 mol percent silver iodide are preferred. Silver chloride grains are not preferred for this purpose.

One of the features of this invention is the position of the colloid layer for adsorbing the organic development inhibitor. In one embodiment of this invention the colloid layer is positioned between the photosensitive emulsion layer containing the interlayer color correction coupler or the organic accelerator for the interlayer interimage efffect and the photosensitive emulsion layer to which the interlayer interimage is provided. In this case the colloid layer captures the development inhibitor released from the photosensitive emulsion layer under the colloid layer to control the working realm of the development inhibitor in a planar direction and to prevent uneven development from occurring.

In a second embodiment of this invention the colloid layer is disposed under the photosensitive emulsion layer, that is to say, at the support side of the photosensitive emulsion layer. In this case the colloid layer captures the development inihibitor released from thephotosensitive emulsion layer to control the development inhibitor from diffusing further and the action of the development inhibitor from spreading in a planar direction further, whereby the uneven development is prevented. Also, by forming the colloid layer at the back side of a support, the colloid layer captures the development inhibitor released in a developer, whereby the developer is prevented from being contaminated by the development inhibitor.

In any of the first embodiment and the second embodiment of this invention, it is preferable that the silver halide grains used in the colloid layer have a mean grain size of less than about 0.2 microns and are silver iodobromide or silver iodide which dissolves in the color developer with difficulty.

The colloid layer of this invention is preferably coated at a coverage of about 0.01 to 10 g, preferably 0.1 to 5 g silver per square meter.

It has been found that if the working realm in a planar direction of the development inhibitor released by development is too broad, the so-called uneven development, that is to say, a Mackie line-like unusual unevenness in color, occurs in a fine color image. This defeet can be improved by the disposition of the colloid layer of this invention.

According to the present invention not only is uneven development prevented but also the uniformity of the development processing can be remarkably improved as the result thereof because by the present invention the release of the organic development inhibitor in the developer, which is a decisive factor in developer contamination, can be prevented.

Another feature of this invention is in a hightemperature development. High-temperature development as used in this invention means development at a temperature higher than about 30C, preferably from about 30 to about 40 or 60C or higher. It is known as shown in Japanese Pat. No. 28836/1970 and French Pat. No. 2,132,675 that the iodine ion released at development is very easily captured by silver chloride or silver bromide in the silver halide grains in the adjacent silver halide emulsion layer due to a replacement reaction reducing the possibility of the release of the organic development inhibitor in the developer, and the replacement reaction is accelerated at higher temperatures to prevent the release of the organic development inhibitor in the developer. On the other hand, the monothio type releasable group as shown in US. Pat. No. 3,227,554 causes chemical adsorption on the silver halide grains in an adjacent silver halide emulsion usually used to form a silver-mercapto compound and at higher temperatures the chemical adsorption tends to be accelerated decreasing the release of the releasable group in the developer. However, interlayer color correction couplers, in particular, the couplers having the releasable groups represented by general formulas (Ia), (lb) and (Ic) and the organic development accelerator for the interlayer interimage effect, in particular, the compounds represented by general formula (II) or (III) (in which, however, R has been substituted with a substituent) have weaker adsorptive ability to the silver halide used in a photographic silver halide emulsion layer than the aforesaid iodine ions and mercapto compounds. Thus, interlayer color correction couplers become readily diffusible and are readily released in the developer when the temperature of the development becomes higher. In such a case, the effect of the employment of the colloid layer for adsorbing organic development inhibitor according to this invention is remarkable.

The couplers used in this invention can be fourequivalent couplers or two-equivalent couplers and in particular, the couplers represented by general formulas (IV), (V) or (VI) described below are useful;

N-Methyl-2-thioxo-6-chloro-quinoline The couplers used in this invention are generally classified into the so-called Fischer type couplers having a water-soluble group such as a carboxyl group, a hydroxyl group, and a sulfo group and hydrophobic couplers.

The coupler used in this invention can be added to a silver halide emulsion or a hydrophilic colloid using any conventional technique. For instance, a method of dispersing the coupler as a mixture of the coupler and a higher boiling (above about 170C) organic solvent such as dibutyl phthalate, tricresyl phosphate, a fatty oil which is a liquid at normal temperature, a wax, a higher fatty acid or an ester thereof as described in, for instance, the specifications of U.S. Pat. Nos. 2,304,939 and 2,322,027; and method of dispersing the coupler as a mixture thereof with a low boiling organic solvent (below about 170C) or a water-soluble organic solvent and a method of dispersing the coupler as this mixture together further with a high boiling organic solvent as described in, for instance, U.S. Pat. Nos. 2,801,170; 2,801,171 and 2,949,360; and a method of dispersing the coupler, when the coupler itself has a sufficiently low melting point (e.g., lower than C), alone or as a mixture thereof with other couplers to be used together, for instance, a colored coupler or an uncolored coupler as described in, for instance, German Pat. No. 1,143,707, can be used.

As a dispersion aid used in such case, an anionic surface active agent (e.g., sodium alkylbenzene sulfonate, sodium octylsulfosuccinate, sodium dodecylsulfate, sodium alkylnaphthalene sulfonate, a Fischer type coupler, etc.), an amphoteric surface active agent (e.g., N- tetradecyl-N,N-dipolyethylene-a-betaine, etc), and a or 6-nitro- 1 5 nonionic surface active agent (e.g., sorbitan monolaurate, etc.) can be used.

The coupler is usually used in an amount of from about 1/10 to 2 per mol of the silver halide. The interlayer color correction coupler can be used alone or as a mixture with other couplers and the amount thereof is usually about 1 to about 50 mol percent, preferably 5 to 20 mol percent to the total amount of the couplers used in a photosensitive emulsion layer.

The organic accelerator for the interlayer interimage effect can be added as a solution in a water-miscible organic solvent such as methanol, ethanol, pyridine, methyl cellosolve, etc., or in water. The amount thereof is usually from about to about 10' mols per mol of silver halide.

The silver halide emulsion used in this invention is a fine dispersion of silver chloride, silver bromide, silver chlorobromide, silver iodobromide, and silver chloroiodo-bromide in a hydrophilic polymer. As the hydrophilic polymer those conventionally used in the photographic art can be advantageously employed including gelatin, a gelatin derivative such as an acylated gelatin, a graft gelatin, etc., albumin, gum arabic. agar agar, a cellulose derivative such as hydroxyethyl cellulose, carboxymethyl cellulose, etc., a synthetic resin such as polyvinyl alcohol, polyvinyl pyrrolidone, polyacrylamide, etc. The silver halide can have a uniform grain size or a broad grain size distribution. Also, the size of the silver halide ranges from about 0.1 microns to about 3 microns. The silver halide emulsion can be prepared using a single jet method, a double jet method, or a combination of these methods or can be matured using,for instance, an ammonia method, a neutralization method, an acid method, etc.

The silver halide emjlsion used as the photosensitive emulsion layer in this invention can be chemically sensitized such as, for instance, by a gold sensitization method as described in U.S. Pat. Nos. 2,399,083; 3,597,856 and 2,597,915; a reduction sensitization method as described in U.S. Pat. Nos. 2,487,850 and 2,521,925; a sulfur sensitization method as described in U.S. Pat. Nos. 1,623,499 and 2,410,689; a sensitization method using metal ions other than silver as described in U.S. Pat. Nos. 2,566,263; 2,566,245; and 2,566,263; or a combination of these methods.

The silver halide emulsion can also be sensitized using a spectral sensitization method which is generally employed in producing color photographic materials. For such purpose a sensitizing dye, such as a cyanine dye or a merocyanine dye, as described in U.S. Pat. Nos. 2,526,632; 2,503,776; 2,493,748; 3,384,486; 2,933,390 and 2,937,089 can be suitably used. The silver halide emulsion used in this invention can further contain a stabilizer such as a 4-hydroxy-l,3,3a,7- tetraazaindene derivative, etc., an antifoggant such as a mercapto compound and a benzotriazole derivative, a coating aid, a hardening agent, a wetting agent, a sensitizer such as an onium derivatives, for instance, a quanternary ammonium salt as described in U.S. Pat. Nos. 2,271,623 and 2,288,226 and also a polyalkylene oxide derivative as described in US. Pat. Nos. 2,708,162; 2,531,832; 2,533,990; 3,210,191; and 3,158,484. The silver halide emulsion layer further can contain an irradiation preventing dye.

Furthermore, the color photographic material of this invention can contain layers such as a filter layer, a mordant dye-containing layer, a colored layer containing a hydrophobic dye, etc.

The silver halide emulsions used in this invention can be coated on various supports such as, for instance, a cellulose acetate film, a polyethylene terephthalate film, a polyethylene film, a polypropylene film, a glass plate, a baryta-coated paper, a resin-coated paper, or a synthetic paper.

The photographic material of this invention is processed with a color developer containing, as a color developing agent, a p-phenylenediamine derivative and a p-aminophenol derivative. Examples of preferred pphenylenediamine derivatives are p-amino-N-ethyl-N- ,B-(methanesulfoamidoethyl)-m-toluidine sesquisulfate monohydrate, diethylamino-p-phenylenediamine sesquisulfite, p-amino-N,N-diethyl-m-toluidine hydrochloride, p-amino-N-ethyl-N-B-hydroxyethylaniline sesquisulfate monohydrate, and the like.

The color photographic materials of this invention can be developed using developers generally used for developing conventional color photographic negative materials, cine color photographic negative or positive materials, color photographic papers, and instant color photographic materials. For instance, the color development processes as described in the specification of British Pat. No. 1,203,316; in U.S. Pat. No. 3,695,883; U.S. Pat. application Ser. No. 234,163, filed Mar. 13, 1972 and Ser. No. 240,287, filed Mar. 31, 1972; H.

The invention is illustrated in greater detail by reference to the following examples which are given for the purpose of understanding the embodiments of this invention and the objects of this invention but are not to be construed limiting the invention. Unless otherwise indicated, all parts, percents, ratios and the like are by weight.

EXAMPLE 1 Sample A as illustrated in FIG. 1 of the accompanying drawings was prepared by coating a first layer, a second layer, a third layer, a fourth layer, and a fifth layer on a transparent cellulose triacetate film as a support. The coating compositions and the preparation methods of the layers were as follows:

FIRST LAYER (BLUE-SENSITIVE EMULSION LAYER) A mixture of 1 kg of a silver iodobromide emulsion (0.52 mol silver and 6 mol percent iodine) and 600 g of Emulsion 1 prepared by dispersing a solution of g of Coupler (4) in a mixture of 100 ml of dibutyl phthalate and 200 ml of ethyl acetate in 1 kg of an aqueous 10 percent gelatin solution using 4 g of sodium dodecylbenzenesulfonate was coated on the support at a coverage of 0.6 g silver per square meter.

SECOND LAYER (GREEN-SENSITIVE EMULSION LAYER) 1 kg of a silver iodobromide emulsion (0.6 mol silver and 6 mol percent iodine) was spectrally sensitized using 2X10 mol of Sensitizing Dye l and 6X10 mol of Sensitizing Dye 11 and then the silver halide emulsion was mixed with 600 g of Emulsion 11 prepared by dispersing a solution of 60 g of Coupler (8) and Coupler (25) in a mixture of 100 ml of tricresyl phosphate and 200 ml of ethyl acetate in 1 kg of an aqueous gelatin solution using 4 g of sodium dodecylbenzenesulfonate to provide the coating composition for the second layer. The coating compossition was then coated on the first layer at a coverage of 0.9 g silver per square meter.

THIRD LAYER (ADSORPTIVE COLLOID LAYER) 1 kg of a silver halide emulsion of super-fine silver iodobromide grains (0.5 mol silver, 2 mol percent iodine, and a mean grain size of 0.05 microns) was coated on the second layer at a thickness of 3 microns (at a coverage of 2.1 g silver per square meter) as the colloid layer for adsorbing an organic development inhibitor of this invention.

FOURTH LAYER (RED-SENSITIVE EMULSION LAYER) 1 kg of a silver iodobromide emulsion (the same as the silver halide emulsion used for forming the first layer) was spectrally sensitized with 4X10 mol of Sensitizing Dye III and 1X10 mol of Sensitizing Dye IV. The silver halide emulsion was mixed with 450 g of Emulsion Ill prepared in the same manner as preparing Emulsion II using 100 g of Coupler (l7) and the coating composition thus formed was coated on the third layer at a coverage of 1.7 g silver per square meter.

FIFTH LAYER (PROTECTIVE LAYER) An aqueous gelatin solution was coated on the fourth layer as the protective layer.

Also, sodium polyvinylbenzenesulfonate as a thick-' ener, sodium dodecylbenzenesulfonate as a surface active agent, and 2-hydroxy-4,6-dichloro-S-triazine sodium salt as a hardening agent for gelatin were added to each of the above-described coating compositions in addition to the above described components.

The materials used for making Sample A were as fol-.

1. Color Development 3 min. sec. 2. Bleach 6 min. 30 sec. 3. Wash 3 min. 15 sec. 4. Fix 6 min. 30 sec. 5. Wash 3 min. l5 sec. 6. Stabilization 3 min. l5 sec.

The formulations of the processing compositions used in the above processing steps were as follows:

Color Developer:

Sodium Nitrilotriacetate l Sodium Sulfite 4 Sodium Carbonate 30. Potassium Bromide l Hydroxylamine Sulfate 2 4-(N-Ethyl-N-B-hydroxyethylamino)- 4 2-methylaniline Sulfate Water to make I Bleach Solution:

Ammonium Bromide Aqueous Ammonia (28%) Sodium Ferric Ethylenediamine Tetraacetic Acid Glacial Acetic Acid Water to make 1 1 Fix Solution:

Sodium Tetrapolyphosphate Sodium Sulfite Ammonium Thiosulfate Sodium Bisulfite Water to make Stabilization Solution:

Formalin (40%) Water to make I I The red filter density and the green filter density were measured for the samples thus processed. The results obtained were shown in FIG. 4 and FIG. 5 of the accompanying drawings. In FIG. 4 curve 1 shows the red filter density of Sample A of this invention and curve 2 shows the green filter density of Sample A and in FIG. 5 curve 3 shows the red filter density of Sample B and curve 4 shows the green filter density of Sample B. As shown in these results, in Sample B the green filter density increased as the exposure amount increased(curved 4) and the red filter density decreased (curve 3) as the exposure amount increased. On the other hand, in Sample A of this invention having the adsorptive colloid layer, the green filter density was almost the same as that of Sample A but no reduction in red filter density (curve 1) was observed. These results show that in Sample B 5-bromobenztriazole released from Coupler (25) in the second layer due to color development diffused into the fourth layer to inhibit the development of the fourth layer, while in Sample A of this invention S-bromobenztriazole released from the coupler in the second layer was captured in the third layer (the adsorptive colloid layer), whereby the diffusion of the development inhibitor into the fourth layer was substantially prevented and the objects of this invention were achieved by the third layer.

Furthermore, samples each the same as Samples A and B prepared above, were uniformly exposed to a red light source under teh same conditions as above, subjected to, then, a line exposure of a width of 500 microns and a length of 10 millimeters using a green light osurce, and then developed using the above-described processing compositions under the following conditions (a), (b), or (c).

a. for 15 minutes at 24C b. for 7 minutes at 30C c. for 4 minutes at 38C In Sample B purple to magenta uneven development was observed around the blue dye images in the strips developed under the conditions (a) and (b), while no uneven development was observed for any of the conditions for Sample A.

EXAMPLE 2 (Demonstration of the effect of the adsorptive colloid layer) Sample C as illustrated in FIG. 2 of the accompanying drawings was prepared by coating the following first layer and second layer on a transparent cellulose triacetate film.

FIRST LAYER (RED-SENSITIVE EMULSION LAYER) The same as the fourth layer of Sample A or B in Example l.

SECOND LAYER (ADSORPTIVE COLLOID LAYER) 1 kg of an emulsion of super fine silver iodobromide grains (0.6 mol silver, 14 mol percent iodine, and a mean grain size of 0.03 microns) was coated on the first layer at a thickness of 3 microns (at a coverage of 2.3 g silver per square meter).

Sample D was prepared in the same manner as described above except that the second layer was a layer of gelatin only having the same thickness as above.

Each of Samples C and D was exposed using a step wedge and then subjected to the same development procedures as in Example 1 (Development (1)). Alternatively, the samples were, after exposure, subjected to the same development procedures of Development (1) except that 0.023 g of S-bromobenztriazole was added to 1 liter of the color developer for Development (1) (Development (2)).

The red filter densities of Sample C in Development (1) and in Development (2) are shown in FIG. 7 as curve (1) and curve (2), respecxtively, and the red filter densities of Sample D in Development (1) and in Development (2) are shown in FIG. 6 as curve l) and curve (2), respectively. As clear from these results, in the case of Sample C having the colloid layer for absorbing an organic development inhibitor, substantially no difference in density between Development (1) and Development (2) was obtained as shown in FIG. 7,

while in the case of Sample D a great reduction in density was observed in Development (2) as compared with Development l) as shown in FIG. 6. Thus, it can be understood that in Sample D S-bromobenztriazole in the developer diffused into the first layer and inhibited the development of the layer, while in Sample C 5-bromobenztriazole was captured by the second layer, whereby the diffusion of the development inhibitor in the first layer was prevented and thus the objects of this invention were attained. In other words, it can be understood that the sample having the colloid layer for' EXAMPLE 3 A multilayer color photographic film, Sample E, as

illustrated in FIG. 3 was prepared by coating the following layers on a cellulose triacetate film.

First Layer (Antihalation layer) A gelatin layer containing black colloidal silver.

Second Layer (Intermediate layer) A gelatin layer containing a dispersion of 2,5-di-toctylhydroquinone.

Third Layer (First red-sensitive emulsion layer):

Eighth Layer (Yellow filter layer) An aqueous gelatin layer containing yellow colloidal silver and a dispersion of 2,5-di-t-octylhydroquinone was coated as the eighth layer.

Ninth Layer (First bluesensitive emulsion layer):

Silver iodobromide emulsion (6 mol% iodine) Coupler (4) Coupler (30) silver coverage of 1 g/m 0.25 mol per mol of silver 00] mol per mol of silver Tenth Layer (Second blue-sensitive emulsion layer):

Twelfth Layer (Protective layer) A gelatin layer containing particles of polymethyl methacrylate (diameter about 1.5 microns).

Each layer described above contained further a hardening agent for gelatin, a surface active agent, and a thickener in suitable amounts in addition to the aforesaid components.

Sample F was also prepared in the same manner as described for Sample E except that the eleventh layer was only a gelatin layer containing no silver halide.

Each of Samples E and F thus prepared was cut into a film of a width of 35 mm and after subjecting to uniform white light exposure, was subjected to Development (1) as described in Example 2. In Sample F the red filter density, the green filter density, and blue filter density were reduced greatly as the exposure amount increased, while in Sample E having the colloid layer for adsorbing the organic development inhibitor according to this invention, the density reduction was much less, attaining sufficiently the objects of this invention.

EXAMPLE 4 Sample G was prepared by forming a layer of silver bromide grains having mean grain size of 0.15 microns at a coverage of 5.5 g silver per square meter on the back surface of the cellulose triacetate film support of Sample F prepared in Example 3. The sample was cut into a film of a width of 35 mm and after being uniformly exposed to white light, was subjected to Development (1) as in Example 3. The results obtained show that the coupling density was reduced as the amount of the film processed increased but the reduction extent was much less than the case of Sample F.

EXAMPLE 5 Sample H was prepared by coating the adsorptive colloid layer, blue-sensitive emulsion layer, greensensitive emulsion layer, red-sensitive emulsion layer, and protective layer using the same coating compositions as used for preparing Sample A in Example 1 on a cellulose triacetate film support. The sample was exposed uniformly to a red light source and then subjected to line exposure using a green light source as in Example 1. The sample was, then, developed using condition (0) as described in Example 1. The formation of uneven development in Smple H was markedly less than for Sample B in Example 1.

EXAMPLE 6 Using the procedure as described in Example 2 samples having the same composition and configuration as Samples C and D were developed in the same manner as described in Example 2 except that l l()" mol of the organic accelerator for the interlayer interimage effect (36) or (37) was added to 1 liter of the developer. The results show that in Sample C having the adsorptive colloid layer the coupling density was hardly reduced, while in Sample D the coupling density was reduced inhibiting the progress of development.

The above fact shows that even in the case of using a developer contaminated with an organic accelerator for the interlayer interimage effect, a color photographic material having the adsorptive colloid layer or the colloid layer for adsorbing the organic development inhibitor according to this invention can be developed without any difficulties occurring.

The present invention can be applied to all color photographic materials containing interlayer color correction couplers or organic accelerators for the interlayer interimage effects and, in particular, the invention is useful for color photographic materials which require faithful color reproducibility, such as color photographic negative films, color photographic reversal films, color photographic transparent positive films, and color photographic papers. Furthermore, the invention can be also applied to radiographic color materials and color photographic micro films in those cases where uniform developed quality is required and the developer is contaminated to a great extent by organic development inhibitors or organic accelerators for the interlayer interimage effect.

While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
