Definitions
- Antistatic agents for use in light-sensitive silver halide photographic materials comprise bis-acyl hydrazinium salts having the formula (III) wherein R R R and R are individually a lower alkyl group; R and R are individually an alkyl, aralkyl or aryl group or a hetero ring; R, is a divalent group; and X is an anion residue.
- This invention relates to new bis-acylhydrazinium compounds. More particularly, this invention relates to a light-sensitive silver halide photographic material comprising a bis-acylhydrazinium salt of the general formula shown later.
- a principal object of the present invention is to provide a light-sensitive silver halide photographic material less subject to problems caused by static.
- Another object of the invention is to provide a lightsensitive radiographic material having improved color tone and a light-sensitive color photographic material having excellent resolution and graininess.
- a light-sensitive silver halide photographic material When developed, a light-sensitive silver halide photographic material frequently forms branch-like or fluify linear spots on the surface thereof. These linear spots are so-called static marks, and it is considered that the formation of such marks is ascribable to the fact that the surface of the light-sensitive material is statically charged due to friction and this static charge is discharged to excite the light-sensitive material. Problems derived from such static charge are not limited merely to the formation of static marks but bring about the adhesion of dust onto the surface of the light-sensitive material. Such static troubles are necessarily brought about at substantially all stages where light-sensitive materials undergo friction, e.g.
- a moistureabsorptive material is frequently incorporated into a certain layer of the light-sensitive material. This procedure, however, is effective only when the humidity is relatively high and is ineffective during dry periods when static problems are brought about frequently. Further, when the humidity is excessively high, the light-sensitive material incorporated with the moisture-absorptive material becomes sticky on the film surface. -In addition to such moisture-absorptive material, a considerable number of compounds have been known as antistatic agents. For application to light-sensitive photographic materials, however, they are required to satisfy such conditions as not to have any detrimental effect on the photographic properties of the light-sensitive material such as sensitivity, gradation, fog, storability, etc. Accordingly, it is extremely difiicult to find excellent antistatic agents applicable to light-sensitive silver halide photographic materials.
- R3 R1 21 R, R 2):
- R R R and R are individually a lower alkyl group; R and R are individually and alkyl, aralkyl or aryl group or a hetero ring; R, is a divalent group; and X is an anion residue.
- any of the above-mentioned compounds is incorporated into at least one of the silver halide emulsion layer, sub layer, inter layer, filter layer, antihalation layer, protective layer and backing layer which are constitutive elements of a light-sensitive silver halide photographic material, it is possible to obtain a light-sensitive silver halide photographic material which is extremely less subject to static problems.
- the incorporation of said compound not only does not have any detrimental effect on the sensitivity, gradation, fog and the like properties of the light-sensitive material but also displays, depending on the kind of light-sensitive material, such favorable effects as to inhibit the fog and enhance the storability of the light-sensitive material.
- the compound when the compound is applied to a light-sensitive radiographic 3 4 material, there is attained the effect, in addition to the is enhanced to make it possible to obtain a color photoprevention of antistatic troubles, that the color tone of graphic material having excellent resolution and grainithe developed silver image can be made bluish black, ness. and when the compound is applied to an internal color
- Typical examples of cretain bis-acylhydrazinium salts photographic emulsion, the dispersibility of the coupler 5 having the aforesaid general formulas are as follows:
- the acylhydrazinium salts are prepared by treating ylides, which are obtained according to the methods disclosed in the above-mentioned references'and R. C. Alagel: Journal of Organic Chemistry, 33 1374 (1968), with hydrochloric acid, hydrobromic acid, hydriodic acid or perchloric acid according to an ordinary procedure.
- the acylhydrazinium fluoroborates are obtained by treating acylhydrazides with trialkyloxonium fluoborates in either or by treating acylhydrazinium chlorides with sodium borofluoride.
- the compound of the present invention may be incorporated into a developing solution, stopping solution, fixing solution, water drop-preventing solution or the like treating bath.
- the amount of the compound is about 0.1 mg. to 1 .g. per 111. of the light-sensitive material, though the amount varies depending on the nature is of the compound and of the layer to which the compound is to be incorporated.
- the compounds of the present invention are usable as well for static charge prevention of cellulose ester, polyester, polystyrene, polycarbonate, polyethylene, polypropylene and the like synthetic resin films, moldings and fibers.
- EXAMPLE 1 Each of the exemplified compounds 2, 5, 10, 14, 17, 22, 26 and 28 was dissolved in ethyl alcohol to form a 1% solution. This solution was spray-coated on the surface of a high sensitivity roentgen film and then dried to prepare a sample. On the other hand, the said high speed roentgen film was dipped in the above-mentioned solution for 1 minute to prepare another sample. For comparison, a control sample was prepared in the same manner as above, except that the above-mentioned treatment was effected by use of only an ethanol solution.
- these samples were exposed to light, developed at C. for 4 minutes and 30 seconds with a strongly alkaline roentgen film developer containing 1- phenyl-3-pyrazolidone hydroquinone (PQ) as developing agent, and then measured in speed and fog'. Further, the samples were subjected to sensitometry after incubation for 3 days in a thermostat chamber kept at 55 C. and
- samples according to the present invention were not deteriorated at all in speed, gradation and fog.
- the color tone of the developed silver changed to bluish black to give favorable results.

G03c 1/82 U.S. CI. 96-87 A 5 Claims ABSTRACT OF THE DISCLOSURE Antistatic agents for use in light-sensitive silver halide photographic materials comprise bis-acyl hydrazinium salts having the formula (III) wherein R R R and R are individually a lower alkyl group; R and R are individually an alkyl, aralkyl or aryl group or a hetero ring; R, is a divalent group; and X is an anion residue.
This invention relates to new bis-acylhydrazinium compounds. More particularly, this invention relates to a light-sensitive silver halide photographic material comprising a bis-acylhydrazinium salt of the general formula shown later.
A principal object of the present invention is to provide a light-sensitive silver halide photographic material less subject to problems caused by static.
Another object of the invention is to provide a lightsensitive radiographic material having improved color tone and a light-sensitive color photographic material having excellent resolution and graininess.
When developed, a light-sensitive silver halide photographic material frequently forms branch-like or fluify linear spots on the surface thereof. These linear spots are so-called static marks, and it is considered that the formation of such marks is ascribable to the fact that the surface of the light-sensitive material is statically charged due to friction and this static charge is discharged to excite the light-sensitive material. Problems derived from such static charge are not limited merely to the formation of static marks but bring about the adhesion of dust onto the surface of the light-sensitive material. Such static troubles are necessarily brought about at substantially all stages where light-sensitive materials undergo friction, e.g. at stages where photographic emulsions are coated on supports, and the resulting film sheets are cut and packed in boxes, or the sheet films are taken out of the boxes and subjected to photographing, and particularly cinefilms which are subjected to photographing or handled before development. The static troubles are brought about also at the time when light-sensitive materials are released. That is, a light-sensitive material, which has been coated with a photographic emulsion and dried, is rolled up, in general, and when this rolled film is successively released in order to subject the film to the subsequent step, a static charge is generated between the surface and the back of the film at the moment when the film is released from the roll. Further, when a light-sensitive photographic printing paper is subjected to ferrotype drying, a static charge is generated between the surface of the film and the metal surface at the time when the printing paper is taken up, to cause the phenomenon that it cannot be superposed immediately on another one.
For the prevention of such static problems, a moistureabsorptive material is frequently incorporated into a certain layer of the light-sensitive material. This procedure, however, is effective only when the humidity is relatively high and is ineffective during dry periods when static problems are brought about frequently. Further, when the humidity is excessively high, the light-sensitive material incorporated with the moisture-absorptive material becomes sticky on the film surface. -In addition to such moisture-absorptive material, a considerable number of compounds have been known as antistatic agents. For application to light-sensitive photographic materials, however, they are required to satisfy such conditions as not to have any detrimental effect on the photographic properties of the light-sensitive material such as sensitivity, gradation, fog, storability, etc. Accordingly, it is extremely difiicult to find excellent antistatic agents applicable to light-sensitive silver halide photographic materials.
We made extensive studies on antistatic agents having no detrimental effect on light-sensitive silver halide photographic materials to find that compounds of the General Formula I, II or III shown below are excellent antistatic agents.

When any of the above-mentioned compounds is incorporated into at least one of the silver halide emulsion layer, sub layer, inter layer, filter layer, antihalation layer, protective layer and backing layer which are constitutive elements of a light-sensitive silver halide photographic material, it is possible to obtain a light-sensitive silver halide photographic material which is extremely less subject to static problems. The incorporation of said compound not only does not have any detrimental effect on the sensitivity, gradation, fog and the like properties of the light-sensitive material but also displays, depending on the kind of light-sensitive material, such favorable effects as to inhibit the fog and enhance the storability of the light-sensitive material. Further, when the compound is applied to a light-sensitive radiographic 3 4 material, there is attained the effect, in addition to the is enhanced to make it possible to obtain a color photoprevention of antistatic troubles, that the color tone of graphic material having excellent resolution and grainithe developed silver image can be made bluish black, ness. and when the compound is applied to an internal color Typical examples of cretain bis-acylhydrazinium salts photographic emulsion, the dispersibility of the coupler 5 having the aforesaid general formulas are as follows:

Further, the compound of the present invention may be incorporated into a developing solution, stopping solution, fixing solution, water drop-preventing solution or the like treating bath. In incorporating the compound into any of the layers constituting a light-sensitive material, the amount of the compound is about 0.1 mg. to 1 .g. per 111. of the light-sensitive material, though the amount varies depending on the nature is of the compound and of the layer to which the compound is to be incorporated.
The compounds of the present invention are usable as well for static charge prevention of cellulose ester, polyester, polystyrene, polycarbonate, polyethylene, polypropylene and the like synthetic resin films, moldings and fibers.
The following examples illustrate the invention.
EXAMPLE 1 Each of the exemplified compounds 2, 5, 10, 14, 17, 22, 26 and 28 was dissolved in ethyl alcohol to form a 1% solution. This solution was spray-coated on the surface of a high sensitivity roentgen film and then dried to prepare a sample. On the other hand, the said high speed roentgen film was dipped in the above-mentioned solution for 1 minute to prepare another sample. For comparison, a control sample was prepared in the same manner as above, except that the above-mentioned treatment was effected by use of only an ethanol solution. The thus prepared samples and an untreated roentgen film were allowed to stand for 24 hours under conditions of RH 30% and 25 C., rubbed on the surfaces with nylon and polyester cloths, and then developed, without exposure, according to an ordinary procedure by use of a radiographic developing solution. Subsequently, the developed samples were individually subjected to Sakura Densitometer (a product of Konishiroku Photo Industry Co., Ltd.) to measure the average values of blackened density. The samples were further measured for the amount of developed silver according to X-ray analysis and, at the same time, for specific surface resistivity. The results obtained were as set forth in Table 1.
