Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a silver halide photographic light-sensitive material, and more particularly to a silver halide photographic light-sensitive material which is prevented from generating static marks and folding fog.

[Background of the Invention] It is known that electrically insulating supports used in photographic materials are easily charged due to friction, peeling, etc., and cause various problems such as dust attraction, electric shock, and ignition. Furthermore, silver halide photographic light-sensitive materials using such supports also undergo various steps during their production, including winding, rewinding, coating of various coating layers including photosensitive layers, and drying. During transportation and other processes, the material becomes charged due to friction or peeling from other substances, and when this discharges, the photographic material coated with the photosensitive layer is exposed to light, and after development, static marks are formed. This causes irregular photosensitive unevenness due to static electricity. Furthermore, when using or processing the manufactured photographic material, static mark failures may similarly occur, and various other harms may occur due to the adhesion of dust and the like. The more sensitive the photosensitive material is, the more this static mark occurs.With the recent increase in the sensitivity of photosensitive materials, not only is there an increasing demand for technology to suppress the generation of static marks, but also Speeding up application in material manufacturing processes;
As drying speeds increase and there are more opportunities for harsh mechanical handling due to high-speed automatic processing, there is an increasing need for technology to suppress the occurrence of various failures due to static electricity charging.

Particularly in recent years, ultra-compact high-speed automatic processing machines called minilabs have rapidly become popular, but most of these machines sandwich silver halide photographic materials between two rubber rollers, press them together from above and below, and transfer them to a developing rack. They are designed to be transported, and the generation of static marks and fog caused by bending in small processing machines has become a concern as silver halide photosensitive materials become more sensitive.

Various methods are known to prevent such failures. A well-known and used method is to provide a conductive layer using a hydrophobic polymer as a binder on the back side of the photographic light-sensitive material (the side without the photographic light-sensitive layer, hereinafter referred to as 80 layer). be.

However, while hydrophobic polymers have small volume changes due to humidity, hydrophilic colloid coatings containing silver halide emulsions,
For example, gelatin coatings have a large volume change due to humidity.

For this reason, silver halide photographic materials that have a silver halide emulsion layer on the front side and a conductive layer with a hydrophobic polymer binder on the back side have a large curl change due to humidity, especially when cut. It was difficult to apply this method to photosensitive materials with large areas. Therefore, at the expense of antistatic performance,
It has been attempted to suppress curl changes by using a hydrophilic colloid layer such as gelatin as the zero layer.

- On the other hand, attempts have also been made to improve the antistatic performance by improving the hydrophilic colloid layer itself.

For example, British Patent No. 861,134, German Patent No. 1

It is known that nonionic surfactants having a polyoxyethylene chain in the molecule shown in No. 08743 and No. 58-203435 have excellent anti-banding properties.

It is also known to reduce the generation of static electricity by incorporating a fluorine-containing compound into a hydrophilic colloid.

For example, British Patent No. 1, 330.356, 1,
No. 524.631, U.S. Patent No. 3.666,478;
3.589.906, Special Publication No. 52-26687,

No. 753,716, No. 4,087,394, Japanese Unexamined Patent Publication No. 1973
Examples include fluorine-containing polymers shown in No. 4-158222 and No. 60-44973.

When these compounds are incorporated into the hydrophilic colloid layer of a silver halide photosensitive material, the antistatic performance is certainly improved, but the antistatic performance is not sufficient with each individual technique alone. In the case of a conductive colloid layer, static marks were more likely to occur and dust was more likely to be adsorbed to the dry film after development than the aforementioned silver halide photographic light-sensitive material in which 80 conductive layers were provided.

For this reason, a technology that prevents static marks by containing a matting agent with a particle size of 3μ or more in the gelatin 80 layer and a polyoxyethylene surfactant and a silicone slip agent in the protective layer of the silver halide emulsion layer. is published in Japanese Patent Publication No. 61-4265.
It is shown in No. 3. In addition, the emulsion layer and protective layer have a grain size of 3 μm.
In JP-A-1988-61, the matting agent described above was developed by incorporating a fluorine-containing surfactant, a polyoxyethylene surfactant, and a silicone slipping agent into 80 layers of gelatin to similarly prevent the generation of static marks. No. 42653.

These techniques include a matting agent with a particle size of 3 μm or more on one surface of two hydrophilic colloid layers sandwiching a support, and an antistatic agent and a lubricating slipping agent on the other surface. Prevents tick marks from occurring. This method prevents the transfer of the silicone slipping agent and prevents to some extent the increase in the occurrence of static marks on silver halide photosensitive materials that have been stored in a rolled state for a long period of time, but the use of a matting agent with a large particle size This leads to devitrification, and the level of antistatic performance is lower than that of the above-mentioned silver halide photographic light-sensitive materials in which a conductive layer is provided on the back surface, making it difficult to apply it to particularly high-sensitivity light-sensitive materials.

The present inventors investigated the relationship between the physical properties of the surfaces of two hydrophilic colloid layers sandwiching a support and the occurrence of static marks, and found that the sliding friction coefficient of the surface of the - side hydrophilic colloid layer, It was found that by suppressing the amount of peeling charge on the surface of the other hydrophilic colloid layer below a certain value, it was possible to suppress the occurrence of static marks, and it was also found that the occurrence of bending fog could be suppressed. .

[Objective of the present invention] Therefore, the first object of the present invention is to suppress the occurrence of static marks, particularly when conveyed with both sides tightly sandwiched between rubber rollers. The second purpose is to prevent the occurrence of folding fog.

[Structure of the Invention] An object of the present invention is to provide a silver halide photographic material having two outermost hydrophilic colloid layers, in which one surface of the outermost layer has a coefficient of static friction of 0.2 or less, and the other surface has a coefficient of static friction of 0.2 or less. This was achieved by setting the absolute value of the peeling charge amount to 200 picocoulombs/Cf or less.

[Specific Structure of the Invention] When the present inventors investigated the relationship between the physical properties of the surface of the two outermost hydrophilic colloid layers on both sides of the support and the occurrence of static marks, it was found that the hydrophilic colloid on the − side When the exfoliation zone 'Flffi on the surface of the outermost layer is suppressed to a certain value of 200 picocoulombs/Cm" or less, and the static friction coefficient of the surface of the other hydrophilic colloid outermost layer is suppressed to a certain value of 0.2 or less. It was found that the occurrence of static marks can be well prevented only by using the following method.

-Generally, there is a method of adding a matting agent to reduce the static *t* coefficient, but the main method is to use a matting agent to reduce the static *t* coefficient.
1! If you try to suppress the friction coefficient to 0.2 or less, the degree of devitrification will increase (the degree of devitrification can be measured using a turbidity meter manufactured by Nippon Precision Engineering (

ter 5EP-PT-201) rl constant torque 2
It was 00 ppm or more. ), the sharpness of the image also decreases. Therefore, methods for obtaining the above static friction coefficient include, for example, waxes, higher fatty acids, higher fatty acid amide compounds,
It is preferable to use friction coefficient reducing agents that do not cause stalling (such as higher fatty acid ester compounds, organopolysiloxane-based slipping agents, etc.) and do not reduce the sharpness of images. Among these friction coefficient reducing agents, organopolysiloxane A method in which a siloxane slip agent is added to the outermost hydrophilic colloid layer is particularly preferred for achieving the objects of the present invention.

In addition, the absolute value of the peeling charge amount is 200 picocoulombs/c
Among various antistatic agents, as a method for reducing the amount to 1 or less,
A method of adding a fluorine-containing compound or a non-ionic surfactant having a polyoxyethylene unit to the outermost layer of a hydrophilic colloid is preferred in order to achieve the object of the present invention.

Next, the organopolysiloxane slip agent, fluorine-containing compound, and nonionic surfactant having polyoxyethylene units used in the present invention will be explained.

Using a nonionic surfactant having ethylene units, the coefficient of static friction of the surface of the outermost layer on the - side is 0.2 or less,
This is a silver halide photographic light-sensitive material in which the two outermost hydrophilic colloid layers are adjusted so that the absolute value of the peel-off charge amount on the surface of the other outermost layer is 200 picocoulombs/(Vt) or less.

In the present invention, the outermost layer of hydrophilic colloid having a surface with a static friction coefficient of 0.2 or less may include waxes, matting agents, etc., in addition to organopolysiloxane, as long as they do not impede the purpose of the present invention. In order to improve this, conventionally used materials can be used in combination. When a matting agent is used in combination, the coating amount is preferably 0.3Q/f or less,
More preferably, it is 0.1 g/V or less.

The silver halide emulsions used in the present invention include conventional silver halide emulsions such as silver bromide, silver iodobromide, silver iodochloride, silver chlorobromide, silver chloroiodobromide, and silver chloride. Any one used can be used.

The silver halide grains used in the silver halide emulsion may be obtained by any of the acid method, neutral method, and ammonia method. The particles may be grown all at once, or may be grown after seed particles are created. The method of creating and growing the seed particles may be the same or different.

In the silver halide emulsion, halide ions and silver ions may be mixed simultaneously, or one may be mixed in a liquid in which the other is present. Further, while taking into consideration the critical growth rate of silver halide crystals, halide ions and silver ions may be generated by sequentially and simultaneously adding them while controlling the pH (11) Alj in the mixing pot. By this method, silver halide grains having a regular crystal shape and a nearly uniform grain size can be obtained. Conversion methods may be used at any step in the formation of AgX to change the halogen composition of the particles.

Various silver halide solvents such as ammonia, thioether, thiourea, etc. can be present during the growth of silver halide grains.

During the process of grain formation and/or growth, silver halide grains are produced using cadmium salts, zinc salts, lead salts, thallium salts, iridium salts (including complex salts), rhodium salts (including complex salts), and iron salts ( Metal ions are added using a small amount (including complex salts) selected from the group consisting of complex salts, and metal ions are added inside the particles and/or
Alternatively, these metal elements can be contained on the particle surface, and reduction sensitizing nuclei can be provided inside the particle and/or on the particle surface by placing the particle in an appropriate reducing atmosphere.

Unnecessary soluble salts may be removed from the silver halide emulsion after the growth of silver halide grains is completed, or they may be left contained. When removing the salts, Research Disclosure (Research D 1
This can be carried out based on the method described in Section 2 of No. 17643 (hereinafter abbreviated as RD).

The silver halide grains may have a uniform silver halide composition distribution within the grain, or may be core/shell grains in which the silver halide composition differs between the inside of the grain and the surface layer.

The silver halide grains may be such that the latent image is mainly formed on the surface, or may be such that the latent image is mainly formed inside the grain.

The silver halide grains may have a regular crystal shape such as a cube, octahedron, or dodecahedron, or may have an irregular crystal shape such as a spherical shape or a plate shape. In these particles, any ratio of the (100) plane to the (111) plane can be used. Further, the particles may have a composite form of these crystal forms, or particles of various crystal forms may be mixed.

The size of silver halide grains is 0.03 to 30μ,
Preferably, a thickness of 0.05 to 10 μm can be used.

Silver halide emulsions having any grain size distribution may be used. An emulsion with a wide grain size distribution (referred to as a polydisperse emulsion) may be used, or an emulsion with a narrow grain size distribution (referred to as a monodisperse emulsion). A particle with a value of 0.20 or less when divided by the average grain size.The grain size is the diameter in the case of spherical silver halide, and the projection of the grain in the case of grains with a shape other than spherical. This indicates the diameter when the image is converted into a circular image with the same area.) may be used alone or in combination. Further, a polydisperse emulsion and a monodisperse emulsion may be mixed and used.

The silver halide emulsion may be a mixture of two or more separately formed silver halide emulsions.

Silver halide emulsions can be chemically sensitized by conventional methods. That is, sulfur sensitization method, selenium sensitization method, reduction sensitization method,
A noble metal sensitization method using gold or other noble metal compounds can be used alone or in combination.

Silver halide emulsions can be optically sensitized to a desired wavelength range using dyes known in the photographic industry as sensitizing dyes. The sensitizing dyes may be used alone or in combination of two or more. Along with the sensitizing dye, the emulsion contains a dye that itself does not have a spectral sensitizing effect, or a supersensitizer, which is a compound that does not substantially absorb visible light and enhances the sensitizing effect of the sensitizing dye. Good too.

Sensitizing dyes include cyanine dyes, merocyanine dyes,
Complex cyanine dyes, complex merocyanine dyes, holopolar cyanine dyes, hemicyanine dyes, steryl dyes and hemioxanol dyes are used.

Particularly useful dyes include cyanine dyes, merocyanine dyes,
and a complex merocyanine pigment.

Silver halide emulsions are used during the manufacturing process of photosensitive materials, during storage,
Alternatively, for the purpose of preventing fog during photographic processing or maintaining stable photographic performance, photographic Compounds known in the art as antifoggants or stabilizers can be added.

It is advantageous to use gelatin as a binder (or protective colloid) for silver halide emulsions, but gelatin derivatives, graft polymers of gelatin and other polymers, other proteins, sugar derivatives, cellulose derivatives, single Alternatively, hydrophilic colloids such as synthetic hydrophilic polymeric substances such as copolymers can also be used.

Photographic emulsion layers and other hydrophilic colloid layers of light-sensitive materials using silver halide emulsions are coated with one or two types of hardeners that crosslink binder (or protective colloid) molecules and increase film strength. By using the above, hardening can be achieved. The hardening agent can be added in an amount that can harden the photosensitive material to the extent that there is no need to add a hardening agent to the processing solution.
It is also possible to add a hardening agent to the processing solution.

For example, aldehydes (formaldehyde, glyoxal, geltaraldehyde, etc.), N-methylol compounds (dimethylol urea, methylol dimethylhydantoin, etc.), dioxane derivatives (2,3-dihydroxydioxane, etc.), activated vinyl compounds (1,3,5- Triacryloyl-hexahydro-s-triazine, 1.3
-vinylsulfonyl-2-propatol, etc.), active halogen compounds (2,4-dichloro-6-hydrooxy-8
-triazine, etc.), mucohalogen acids (mucochloric acid, mucophenoxychloroic acid, etc.), etc. can be used alone or in combination.

A plasticizer may be added to the silver halide emulsion layer and/or other hydrophilic colloid layer of the light-sensitive material of the present invention for the purpose of increasing flexibility. Preferred plasticizers are X of RD 17643
It is a compound described in A of item (2).

The photographic emulsion layer and other hydrophilic colloid layers of the light-sensitive material may contain a dispersion (latex) of a water-insoluble or sparingly soluble synthetic polymer for the purpose of improving dimensional stability.

For example, alkyl (meth)acrylate, alkoxyalkyl (meth)acrylate, glycidyl (meth)acrylate, (meth)acrylamide, vinyl ester (e.g. vinyl acetate), acrylonitrile, olefin, styrene, etc. alone or in combination, or these and acrylic acid, A polymer containing a combination of methacrylic acid, α, β-unsaturated dicarboxylic acid, hydroxyalkyl (meth)acrylate, sulfoalkyl (meth)acrylate, styrene sulfonic acid, etc. as a monomer component can be used.

The emulsion layer of the photosensitive material contains a dye-forming agent that forms a dye through a coupling reaction with an oxidized form of an aromatic primary amine developer (for example, p-phenylenediamine derivatives, aminophenol derivatives, etc.) during color development processing. A coupler is used. The dye-forming couplers are typically selected for each emulsion layer such that a dye is formed that absorbs light in the light-sensitive spectrum of the emulsion layer, with a yellow dye-forming coupler for the blue-sensitive emulsion layer and a dye for the green-sensitive emulsion layer. A magenta dye-forming coupler is used in the sensitive emulsion layer and a cyan dye-forming coupler is used in the red-sensitive emulsion layer. However, depending on the purpose, silver halide color photographic materials may be produced using different combinations from the above.

These dye-forming couplers preferably have a group called a ballast group in the molecule, which makes the coupler non-diffusive and has 8 or more carbon atoms. In addition, even if these dye-forming couplers are 4-equivalent, in which 4 silver ions need to be reduced in order to form one molecule of dye, only 2 silver ions need to be reduced. Either authority is fine. Dye-forming couplers include colored couplers that have a color correction effect and, by coupling with oxidized forms of developing agents, can be used as development inhibitors, development accelerators, bleaching accelerators, developers, silver halide solvents, and toning agents. Compounds that release photographically useful fragments such as hardeners, fogging agents, antifoggants, chemical sensitizers, spectral sensitizers, and desensitizers are included. Among these, couplers that release a development inhibitor during development and improve image sharpness and image graininess are called DIR couplers. In place of the DIR coupler, a DIR compound which undergoes a coupling reaction with the oxidized form of the developing agent to produce a colorless compound and at the same time releases a development inhibitor may be used.

The DIR couplers and DIR compounds used include those with an inhibitor directly attached to the coupling position and those with an inhibitor attached to the coupling position.
It is bonded to the coupling position via a valent group, and the inhibitor is released by an intramolecular nucleophilic reaction within the group separated by the coupling reaction, an intramolecular electron transfer reaction, etc. (referred to as timing DIR couplers and timing DIR compounds). Also, depending on the purpose, inhibitors that can be dispersed after release and those that are not so dispersible can be used alone or in combination. A colorless coupler (also called a competitive coupler) which undergoes a coupling reaction with an oxidized aromatic primary amine developer but does not form a dye can also be used in combination with a dye-forming coupler.

As the yellow dye-forming coupler, various acylacetanilide couplers can be preferably used.

Among these, benzoylacetanilide and pivaloylacetanilide compounds are advantageous. Specific examples of yellow coloring couplers that can be used include, for example, U.S. Patent No. 2,87

As is clear from Table 1, the coefficient of static friction on one surface of the outermost layer is 0.2 or less, and the absolute value of the peeling charge amount on the other surface is 2.
Samples A, B, C, and D of the present invention, which were adjusted to 00 picocoulombs/CV or less, showed no static marks even when conveyed tightly between neoprene rubber rollers, and did not suffer from sudden bending. No fog occurs even if

On the other hand, samples A and A were not subjected to the above adjustment, and static marks were observed, and the amount of bending fog increased.
