[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide photographic material which prevents the occurrence of pressure fog in a processing solution of the silver halide photographic material and has improved resistance to static electricity.

0002

BACKGROUND OF THE INVENTION When silver halide photographic materials are processed by an automatic processor, the material is generally conveyed by many rollers, and the surface of the material is subjected to strong pressure from the rollers in a wet state. This wet pressure in the liquid causes fatal problems such as fog and desensitization to the photosensitive material, just as when it is dry.

[0003] Methods for preventing such fogging include, for example, increasing the hardness of the film and increasing the amount of binder, and the technique disclosed in Japanese Patent Publication No. 40665/1983, which uses a quaternary phosphonium salt compound with oxidizing properties. It has been known.

Furthermore, as a method for improving the physical properties of a silver halide photographic light-sensitive material, it is also known to use, for example, a polymer latex together with gelatin as a binder. However, oxidizing compounds have desensitizing properties, latex devitrifies during development processing, increases dye staining, and although it is effective against roller pressure when dry, it is not effective at preventing fog when wet. At present, there are still many problems such as:

[0005] Apart from such pressure resistance, it is also important to impart antistatic properties to photosensitive materials, and it is required that the photosensitive materials have stable antistatic properties without deteriorating even when stored over time. Ru. For this reason, there was a strong desire to develop new technology.

[0006]

OBJECTS OF THE INVENTION Accordingly, a first object of the present invention is to provide a silver halide photographic light-sensitive material in which the occurrence of pressure fog caused by roller pressure of an automatic processing machine is prevented from occurring in a processing solution. A second object of the present invention is to provide a silver halide photographic material that exhibits no deterioration in surface resistivity during storage over time and has excellent resistance to static electricity. Other objectives will become apparent from the description below.

[0007]

SUMMARY OF THE INVENTION The above object of the present invention is to provide a silver halide photographic material having at least one silver halide emulsion layer and a hydrophilic colloid layer on a support. The grain size is 200 nm or less and the glass transition temperature is 0°C to -1 between the undercoat layer and the silver halide emulsion layer.
This is achieved by a silver halide photographic light-sensitive material having a latex layer containing at least one polymer latex having a temperature of 00°C. The present invention will be explained in detail below.

The latex according to the present invention is a polymerizable ethylene compound or a polymerizable diolefin compound, and is roughly classified into hydrophobic monomers and hydrophilic monomers. Examples of hydrophobic monomers include methyl acrylate, ethyl acrylate, butyl acrylate, hexyl acrylate,
Acrylic acid alkyl esters such as 2-ethylhexyl acrylate and t-butyl acrylate, methyl methacrylate, ethyl methacrylate, butyl methacrylate, hexyl methacrylate, octyl methacrylate, 2-ethylhexyl methacrylate, t-butyl methacrylate, iso-propyl methacrylate, etc. Glycidyl esters such as methacrylic acid alkyl esters, glycidyl acrylate, glycidyl methacrylate, alkenylbenzenes such as styrene, vinyltoluene, α-methylstyrene, chloromethylstyrene, vinyl esters such as vinyl acetate and vinyl propionate, methyl vinyl ether , vinyl ethers such as ethyl vinyl ether and phenyl vinyl ether, vinyl halides such as vinyl chloride, vinyl bromide and vinylidene chloride, amides such as acrylamide and methacrylic acid amide, and diene monomers such as butadiene. can. Hydrophilic monomers include hydroxyalkyl acrylates such as hydroxyethyl acrylate and hydroxypropyl acrylate; hydroxyalkyl methacrylates such as hydroxyethyl methacrylate and hydroxypropyl methacrylate; meth) ethylene glycol acrylate, acrylic acid, methacrylic acid,
Examples include ionic monomers such as itaconic acid and α-acrylamido-2-methylpropanesulfonic acid. These monomers may be used alone or in combination of two or more types, but when using a hydrophilic monomer, it is preferable to use it in combination with a hydrophobic monomer to obtain a stable latex. It is better not to use too large amounts of hydrophilic monomers.

The latex according to the present invention may be obtained by an emulsion polymerization method or a suspension polymerization method in which the latex is polymerized in a dispersion medium from the beginning, or the latex can be obtained by polymerizing separately, taking out the polymer, and redispersing it. However, the emulsion polymerization method is preferable from the viewpoint of manufacturing cost, dispersion stability, etc.

Polymerization of the latex according to the present invention can be carried out by the method described in JP-A-60-4501.

[0011] Considering that the emulsifier used in the polymerization is used in a photographic emulsion, it should not be used at all, or it should be one that has little effect on the photographic emulsion used, but the emulsifier should be used to an extent that does not impair the effects of the present invention. You may do so. The polymerization initiator used in the polymerization is preferably a radical polymerization initiator, and particularly preferably a water-soluble radical polymerization initiator such as potassium persulfate.

[0012] The latex according to the present invention has a particle size of 200
The particle size may be smaller than 100 nm, preferably 100 nm or less, more preferably 50 nm or less, and a smaller particle size is selected. Also, the glass transition point is 0°C to -100°C, preferably -2
By selecting a softer latex in the range of 0°C to -80°C, more preferably -30°C to -60°C, the objective effects of the present invention can be favorably achieved.

The object of the present invention can be satisfactorily achieved by providing a layer containing the latex of the present invention between a subbing layer and a silver halide emulsion layer coated on a support.
If the latex layer is above the emulsion layer or on a protective layer above the emulsion layer, the effects of the present invention cannot be obtained. The latex according to the present invention may be used in constituent elements of silver halide photographic light-sensitive materials other than the latex layer, such as emulsion layers, protective layers, filter layers, intermediate layers, and antihalation layers, and when the latex according to the present invention described above is used. A latex layer may also be provided.

When the latex according to the present invention is applied onto a support having an undercoat layer, it is applied after being dissolved in water or a hydrophilic solvent such as methanol or ethanol. Alternatively, a latex emulsified and dispersed in a hydrophilic binder such as gelatin may be applied. The amount of latex applied may be 50 mg to 5000 mg/m2, preferably 100 mg to 1000 mg. The latex layer coating liquid according to the present invention may contain various coating aids, such as surfactants, hardeners, film-forming agents, and other compounds, if necessary. The hydrophilic colloid layer referred to in the present invention is

The emulsion used in the silver halide photographic light-sensitive material of the present invention may be any silver halide such as silver iodobromide, silver iodochloride, and silver iodochlorobromide, but particularly those with high sensitivity are preferred. In terms of availability, silver iodobromide is preferred.

In this manner, 15 types of samples shown in Table 2 were prepared, and the sensitivity, submerged pressure Fog, and surface resistivity were evaluated.

(1) Sensitivity measurement The sample was sandwiched between two fluorescent intensifying screens KO-250, and the tube voltage:
80Kvp Tube current: 100mA Irradiation time: 50msec After exposure through aluminum steps, development was performed with XD-90 developer using a KX-500 automatic developing machine at 35°C for 30 seconds, and fixed with XF ( (all manufactured by Konica Co., Ltd.), then washed with water according to the usual method.
For the sample obtained by drying, the reciprocal of the exposure amount required to obtain a density of base density + fog density + 1.0 was determined and used as the sensitivity. The sensitivity in the table is for sample No. 1 sensitivity to 10
It is expressed as relative sensitivity when it is set to 0.

(2) Evaluation method of liquid pressure Fog (fog)
Cut to 7 x 305 mm, density after development is approximately 1.0.0
．． Two types of samples were prepared: one that had been exposed in advance to have three levels of density in the exposed area, such as 0.6 and 0.4, and one that had not been exposed.

The exposed and unexposed samples were treated in the same manner as in the sensitivity measurement, then washed with water and dried. The appearance of black spot marks on the obtained samples was evaluated in the following five stages.

◎: Not occurring at all ○: Slightly occurring △: Occurring, barely practical level ×: Occurring a lot, impractical ××: Significantly occurring (3) Surface specific resistance Measuring Method The sample was placed between brass electrodes with an electrode spacing of 0.14 cm and a length of 10 cm, and measurement was performed for 1 minute using an insulation tester model TR8651 manufactured by Takeda Riken. The sample below before development was heated to 25°C and RH.
The humidity was adjusted to below 20% for 2 hours and then measured.

Fresh sample: Measure the sample immediately Preserved sample (1): Temperature 23°C, RH 55% humidity condition
Storage for 1 day (2): After adjusting the humidity to 23°C and 55% RH for 3 hours, seal in a moisture-proof bag with a layer of film and store at 55°C for 3 days. The results are shown in Tables 2-1 and 2-2. Shown below.
