Description
20651~6 SILVER HALIDE PHOTOGRAPHIC LIGHT-SENSITIVE MATERIAL AND
PHOTOGRAPHIC PRODUCT FOR FILM-MAKING PROCESS
FIELD OF THE INVENTION
The present invention relates to a silver halide photographic light-sensitive material and photographic product for film-making process which can be used to form a photographic image with very high contrast, more specifically a silver halide photographic light-sensitive material and photographic product for film-making process which can be used to form a dot image with high contrast and which are very useful in the field of film-making process.
~ACKGROUND OF THE INVENTION
The film-making process includes a process in which an original with continuous gradation is converted to a dot image or the density change in continuous gradation is 2~651~6 converted to a group of dots having an area in proportion to that density.
This process is based on a photographic technology making it possible to reproduce an image with very high contrast, by which the original is subjected to exposure via a cross-line screen or contact screen, followed by infections development to form a dot image.
Lith-typed silver halide photographic light-sensitive materials, used for infections development, does not offer sufficient contrast unless processed with a infections developer (lith developer). For example, when processed with an MQ developer or PQ developer, they have a gamma value of at most S to 6, and are significantly affected by the occurrence of fringe, which is the most undesirable in forming dots. For these reasons, they should be used in combination with infections developers, which are poor in preservability.
With this background, there have been developed some methods of forming an image with very high contrast comparable to that obtained by infections development using a developer which has a high sulfite ion concentration and good preservability and permits rapid processing, including the known method disclosed in Japanese Patent Publication Open to Public Inspection (hereinafter referred to as Japanese Patent O.P.I.
20S~
~ 3 --Publication) No. 106299/1981. In this method, a compound known as a contrast increasing agent is added to a silver halide photographic light-sensitive material or used in combination with specific silver halide grains and other photographic additives in order to show a contrast increasing effect.
The use of such a silver halide photographic light-sensitive material makes it possible to obtain a photographic image with very high contrast even when it is processed with a highly preservable, rapidly processable developer. However, it has a drawback that sand-like or pin-like fogging, namely Pepper fog, occurs in dots during formation of dot image, which adversely affects the dot image quality. To solve this problem, various attempts have been made in which various stabilizers or inhibitors having a hetero atom were added, but none of them reach a solution to this problem.
In addition, this type of silver halide photographic light-sensitive material is also faulty that it is likely to undergo silver image deterioration and discoloration over time.
SUMMARY OF THE INVENTION
The present invention has been made in order to solve the above-described problems.

Although the denatured gelatin coagulant can be used at any time during production of silver halide photographic emulsion, it is preferable to use it during or after the desalinization process, more preferably during the desalinization process, since it is more effective on photographic performance that contrast degradation does not occur. Although the amount of its addition is not subject to limitation, the amount i9 preferably 0.1 to 10 times, more preferably 0.2 to 5 times by weight greater than the amount of the substance (preferably gelatin) contained as protective colloid, after desalting, when it is used in the desalting process.
The denatured gelatin coagulant acts to coagulate silver halide grains along with protective colloid, and can be allowed to coagulate the silver halide emulsion by ad~usting the pH after its addition. The pH at coagulation is not more than 5.5, preferably 4.8 to 2.
Although any acid can be used for pH adjustment with no limitation, organic acids such as acetic acid, citric acid and salicylic acid and inorganic acids such as hydrochloric acid, nitric acid, sulfuric acid and phosphoric acid are preferably used. The denatured gelatin coagulant may be used in combination with heavy metal ions such as magnes.ium ion, cadmium ion, lead ion and zirconium ion.
' Removal of dissolved substances (desalting) may be performed once or in several cycles. When it is performed in several cycles, the denatured gelatin coagulant may be added at every removal or only once at the initial.
For producing the silver halide photographic emulsion relating to the present invention, gelatin is normally used as a binder or protective colloid, but other substances can also be used for this purpose, including gelatin derivatives, graft polymers of gelatin and another polymer, proteins such as albumin and casein, cellulose derivatives such as hydroxyethyl cellulose and carboxymethyl cellulose, sugar derivatives such as agar, sodium alginate and starch derivatives, various synthetic hydrophilic homopolymers and copolymers such as polyvinyl alcohol, poly-N-vinylpyrrolidone, polyacrylic acid, polyacrylimide, polyvinylimidazole and polyvinylpyrazole.
The silver halide used in the silver halide photographic light-sensitive material of the present invention is described below. The silver halide may have any composition, including silver chloride, silver chlorobromide, silver chloroiodobromide, silver bromide and silver iodobromide. The average grain size of the silver halide grains is preferably in the range from 0.05 to 0.5 ~m, more preferably 0.10 to 0.40 ~m.
2~6~6 Although the silver halide grains for the present invention may have any grain size distribution, it is preferably 1 to 30, more preferably 5 to 20 in terms of the degree of monodispersion as defined below.
Here, the degree of monodispersion is defined as the figure obtained by dividing the standard deviation of grain size by average grain size and multiplying the quotient by a factor of 100. For convenience, the grain size of silver halide grains is expressed by the length of ridge for cubic grains or by the square root of projected area for other types of grains such as octadecahedral and tetradecahedral grains.
In the present invention, it is possible to use silver halide grains having at least two laminated layers.
For example, silver iodobromide grains comprising silver iodobromide in the core and silver bromide in the shell can be used. In this case, iodine can be contained in any layer at contents of not more than 5 mol%.

PHOTOGRAPHIC PRODUCT FOR FILM-MAKING PROCESS
FIELD OF THE INVENTION
The present invention relates to a silver halide photographic light-sensitive material and photographic product for film-making process which can be used to form a photographic image with very high contrast, more specifically a silver halide photographic light-sensitive material and photographic product for film-making process which can be used to form a dot image with high contrast and which are very useful in the field of film-making process.
~ACKGROUND OF THE INVENTION
The film-making process includes a process in which an original with continuous gradation is converted to a dot image or the density change in continuous gradation is 2~651~6 converted to a group of dots having an area in proportion to that density.
This process is based on a photographic technology making it possible to reproduce an image with very high contrast, by which the original is subjected to exposure via a cross-line screen or contact screen, followed by infections development to form a dot image.
Lith-typed silver halide photographic light-sensitive materials, used for infections development, does not offer sufficient contrast unless processed with a infections developer (lith developer). For example, when processed with an MQ developer or PQ developer, they have a gamma value of at most S to 6, and are significantly affected by the occurrence of fringe, which is the most undesirable in forming dots. For these reasons, they should be used in combination with infections developers, which are poor in preservability.
With this background, there have been developed some methods of forming an image with very high contrast comparable to that obtained by infections development using a developer which has a high sulfite ion concentration and good preservability and permits rapid processing, including the known method disclosed in Japanese Patent Publication Open to Public Inspection (hereinafter referred to as Japanese Patent O.P.I.
20S~
~ 3 --Publication) No. 106299/1981. In this method, a compound known as a contrast increasing agent is added to a silver halide photographic light-sensitive material or used in combination with specific silver halide grains and other photographic additives in order to show a contrast increasing effect.
The use of such a silver halide photographic light-sensitive material makes it possible to obtain a photographic image with very high contrast even when it is processed with a highly preservable, rapidly processable developer. However, it has a drawback that sand-like or pin-like fogging, namely Pepper fog, occurs in dots during formation of dot image, which adversely affects the dot image quality. To solve this problem, various attempts have been made in which various stabilizers or inhibitors having a hetero atom were added, but none of them reach a solution to this problem.
In addition, this type of silver halide photographic light-sensitive material is also faulty that it is likely to undergo silver image deterioration and discoloration over time.
SUMMARY OF THE INVENTION
The present invention has been made in order to solve the above-described problems.

Although the denatured gelatin coagulant can be used at any time during production of silver halide photographic emulsion, it is preferable to use it during or after the desalinization process, more preferably during the desalinization process, since it is more effective on photographic performance that contrast degradation does not occur. Although the amount of its addition is not subject to limitation, the amount i9 preferably 0.1 to 10 times, more preferably 0.2 to 5 times by weight greater than the amount of the substance (preferably gelatin) contained as protective colloid, after desalting, when it is used in the desalting process.
The denatured gelatin coagulant acts to coagulate silver halide grains along with protective colloid, and can be allowed to coagulate the silver halide emulsion by ad~usting the pH after its addition. The pH at coagulation is not more than 5.5, preferably 4.8 to 2.
Although any acid can be used for pH adjustment with no limitation, organic acids such as acetic acid, citric acid and salicylic acid and inorganic acids such as hydrochloric acid, nitric acid, sulfuric acid and phosphoric acid are preferably used. The denatured gelatin coagulant may be used in combination with heavy metal ions such as magnes.ium ion, cadmium ion, lead ion and zirconium ion.
' Removal of dissolved substances (desalting) may be performed once or in several cycles. When it is performed in several cycles, the denatured gelatin coagulant may be added at every removal or only once at the initial.
For producing the silver halide photographic emulsion relating to the present invention, gelatin is normally used as a binder or protective colloid, but other substances can also be used for this purpose, including gelatin derivatives, graft polymers of gelatin and another polymer, proteins such as albumin and casein, cellulose derivatives such as hydroxyethyl cellulose and carboxymethyl cellulose, sugar derivatives such as agar, sodium alginate and starch derivatives, various synthetic hydrophilic homopolymers and copolymers such as polyvinyl alcohol, poly-N-vinylpyrrolidone, polyacrylic acid, polyacrylimide, polyvinylimidazole and polyvinylpyrazole.
The silver halide used in the silver halide photographic light-sensitive material of the present invention is described below. The silver halide may have any composition, including silver chloride, silver chlorobromide, silver chloroiodobromide, silver bromide and silver iodobromide. The average grain size of the silver halide grains is preferably in the range from 0.05 to 0.5 ~m, more preferably 0.10 to 0.40 ~m.
2~6~6 Although the silver halide grains for the present invention may have any grain size distribution, it is preferably 1 to 30, more preferably 5 to 20 in terms of the degree of monodispersion as defined below.
Here, the degree of monodispersion is defined as the figure obtained by dividing the standard deviation of grain size by average grain size and multiplying the quotient by a factor of 100. For convenience, the grain size of silver halide grains is expressed by the length of ridge for cubic grains or by the square root of projected area for other types of grains such as octadecahedral and tetradecahedral grains.
In the present invention, it is possible to use silver halide grains having at least two laminated layers.
For example, silver iodobromide grains comprising silver iodobromide in the core and silver bromide in the shell can be used. In this case, iodine can be contained in any layer at contents of not more than 5 mol%.

They 206~1~6 may also have a reduction sensitizing nucleus therein and/or thereon by keeping them in appropriate reducing atmosphere.
The silver halide may also be sensitized with various chemical sensitizers. Examples of sensitizers include active gelatin, sulfur sensitizers such as sodium thiosulfate, allyl thiocarbamide, thiourea and allyl isothiocyanate, selenium sensitizers such as N,N-dimethylselenourea and selenourea, reduction sensitizers such as triethylenetetramine and stannous chloride and various noble metal sensitizers such as potassium chloroaurate, potassium aurothiocyanate, potassium chloroaurate, 2-aurosulfobenzothiazole methylchloride, ammonium chloropalladate, potassium chloroplatinate and sodium chloropalladate. These sensitizers may be used single or in combination. When using a gold sensitizer, rhodan ammonium may be used as an auxiliary.
The silver halide grains for the present invention can be improved in their performance by processing with the chemical sensitizers described above, because they are preferably silver halide grains offering negative images, namely grains wherein the surface sensitivity is higher than the inside sensitivity.
