Description

Detailed Description of the Invention (Prior Art and its Problems) -a. Silver halide photographic light-sensitive materials have a photographic layer using hydrophilic colloid as a binder, so the photographic layer does not expand or contract due to changes in temperature and humidity. It has the disadvantage of causing dimensional changes due to development processing.

This dimensional change in silver halide photographic materials is an extremely serious drawback in silver halide photographic materials for printing, which require reproduction of halftone images and precise line drawings for multicolor printing. .

Various means have been known for improving the dimensional stability of silver halide photographic materials.

For example, U.S. Pat.
No. -4272, No. 39-17702, No. 43-134
No. 82, No. 45-5331, U.S. Patent No. 237.600
No. 2,763°625, No. 2,772,166, No. 2,852.386, No. 2,853,457,
No. 3,397,988, No. 3,411,911, and No. 3,411,912 describe a method of adding a polymer latex to a parent wood colloid photographic layer.

It is true that by using these techniques, it is possible to improve dimensional changes in silver halide photographic materials due to changes in temperature and humidity.

However, these techniques cannot prevent dimensional changes caused by the development process of silver halide and photographic light-sensitive materials. The phenomenon of dimensional change accompanying this development process is
Due to the phenomenon that the dimensions of silver halide photographic light-sensitive materials change due to development processing, the dimensions change during exposure and after development.
This is a very serious drawback in the use of silver halide photographic materials.

In order to improve the dimensional stability accompanying this development process, Japanese Patent Application No. 62-94133 describes a technique using a vinylidene chloride undercoat layer.

However, even if this technique is used, it is not possible to completely improve the dimensional stability associated with development processing, and improvement in this point has been desired.

(Object of the Invention) An object of the present invention is to provide a silver halide photographic material with improved dimensional stability during development.

As a result of intensive research, the inventors have discovered that the method described in the present invention provides a surprising effect of improving "dimensional stability accompanying development processing," which is completely different from previously known methods. .

(Structure of the Invention) The object of the present invention is to provide a silver halide photographic material having a hydrophilic colloid layer containing a polymer latex on at least one side of a polyester support. After applying the coating solution and drying it, the silver halide photographic light-sensitive material is kept at an absolute humidity of 1%.
This was achieved by a silver halide photographic material, which is heat-treated at a temperature of 30° C. or higher in the following atmosphere and stored in an atmosphere with an absolute humidity of 1% or less. .

(Specific structure of the invention) The heat treatment of the present invention needs to be performed at a temperature of 30°C or higher, preferably 35°C or higher and 50°C or lower, more preferably 35°C or higher and 45°C or lower. can. The heat treatment time cannot be determined depending on the temperature, but for example, 45
℃, preferably about 6 hours or more.

The humidity during the heat treatment needs to be 1% or less absolute humidity, more preferably 0.8% or less.

Air absolute humidity is defined as the ratio of the weight of water vapor in the air to the weight of air. For example, 1% absolute humidity is equivalent to approximately 50% RH at 25°C, and approximately 2% relative humidity at 40°C.
Corresponds to 1% RH.

The heat treatment of the present invention can be performed at any time after coating and drying the silver halide photographic material.

The silver halide photographic material (i) is manufactured through a process of coating and drying, then winding up into a roll, and then cutting to a predetermined size and packaging. Therefore, for example, if the silver halide photographic light-sensitive material is stored at an absolute humidity of 1% or less, the heat treatment of the present invention can be carried out at the point when it is wound up into a roll after coating and drying, at the point at which it is cut, or at the point at which it is packaged. It can be applied at any time.

In the present invention, the silver halide photographic material must be stored at an absolute humidity of 1% or less. Storing here means storing the photosensitive material under the conditions of the present invention for a period of time until the -1%i user uses the photosensitive material.

For this purpose, for example, a method is used in which a silver halide photographic material that has been left in this temperature and humidity atmosphere for a sufficient period of time is hermetically packaged using a moisture-proof packaging material. Another method is to reduce the moisture content of the core and paper that are packaged together with the silver halide photographic material in advance, and then reduce the temperature and humidity inside the package to below the absolute humidity ratio after the package is sealed. Can be used.

It is also effective to seal and package a desiccant such as silica gel together with the silver halogenide photographic material.

The package for hermetically packaging the silver halide photographic light-sensitive material of the present invention may have any shape as long as it can seal the silver halide photographic light-sensitive material. Various shapes of the package can be considered depending on the shape and shape. Usually, a packaging bag made by heat sealing is preferably used. The material that makes up the packaging bag is a polyethylene film with low moisture permeability (usually polyethylene contains carbon black, etc., to provide light-shielding properties and to make the surface of the polyethylene slippery, which has a negative impact on photosensitive materials). It is preferable to use a material containing a substance that does not contain a Another preferred form is a packaging bag overlaid with an aluminum thin film. Preferred examples of these packaging bags include JP-A-67-J7J, JP-A-5.1' 132663, and JP-A-J/-/
Examples include packaging materials disclosed in No. 19936 and the like.

When the silver halide photographic material of the present invention is packaged in these packaging bags, the packaging may be carried out under reduced pressure to reduce the amount of air inside the packaging bag.

That is, in the present invention, it is necessary that the photosensitive material be placed in an atmosphere with an absolute humidity of less than 1% until the photosensitive material is used by a general user.

The polyester used in the support of the present invention is a polyester whose main components are an aromatic dibasic acid and glycol. Typical dibasic acids include terephthalic acid, isophthalic acid, and p-β-oxyethoxy7benzoic acid. , diphenylsulfone dicarboxylic acid, diphenoxyethane dicarboxylic acid, adipic acid, sebacic acid, azelaic acid,! -Sodium sulfoiphthalic acid, diphenylene dicarboxylic acid, J, J-naphthalene dicarboxylic acid, etc. Glycols include ethylene glycol, propylene glycol, butanediol, Neo is ethylene glycol%/l
Examples include μm cyclohexanediol, 4Z-7 chlorhexanedimethanol%/l ≠-bisoxyethoxybenzene, bisphenol A1 diethylene glycol, polyethylene glycol, and the like.

Among the polyesters made of these components, polyethylene terephthalate is the most convenient in terms of availability.

There is no particular limit to the thickness of polyester, but it is approximately 12μ.

6-Methyl-1,3,3a,7-chitrazaindene was added. A tetrazolium salt was added to this emulsion at 5.times.10@-3 moles per mole of Ag. Furthermore, as a polymer latex, polymer 3 is added to an emulsion of 1.4
The gelatin hardener used was the same compound as in Example 1. This emulsion was coated with a coating silver amount of 3
．． It was applied so that the amount of gelatin was 9 g/m and the amount of gelatin was 3.1 g/rrr.

(2) Developer formulation Ethylenediaminetetraacetic acid dinatrirum salt (dihydrate) 0.75g Anhydrous potassium sulfite 51.7g Anhydrous potassium carbonate 60.4g Hydroquinone
15.1g 1-phenyl-3-pyrazolidone 0.51g Sodium bromide 2
．． 2g5-methylbenzotriazole 0.124g1
-Phenyl-5-mercaptotitrazole 0.018g5-nitro-indazole 0.106gDiethylene glycol 98gAdd water 17!
(pH=10.5) As can be seen from Table 5, the dimensional stability accompanying the development process was improved in the samples subjected to the heat treatment and storage conditions of the present invention, and the effects of the present invention are clear.
