Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide photographic light-sensitive material, and more particularly to a silver halide photographic light-sensitive material having a good curl, an improved drying property during development and a reduced carryover amount. Further, the present invention relates to a silver halide photographic light-sensitive material which prevents halation and has good image quality.

[0002]

2. Description of the Related Art Recently, in silver halide photographic light-sensitive materials, there has been a demand for speeding up and simplifying development processing. It is effective to reduce the drying load of the silver halide photographic light-sensitive material in order to accelerate the development processing. Further, in order to simplify the development processing, it is effective to reduce carryover of the silver halide photographic light-sensitive material. For these purposes, Japanese Patent Application No. 3-1
The specification of 45168 describes a method of forming a hydrophobic polymer layer on a non-photosensitive hydrophilic colloid layer on the surface opposite to the surface on which the silver halide emulsion layer is coated (back surface). By using this method, the drying load and the carry-over amount can be remarkably reduced, which is extremely advantageous in speeding up and simplifying the developing process.

On the other hand, in the case of silver halide photographic light-sensitive materials, the incident light, which has passed through the silver halide emulsion layer or scattered in the layer, is a non-photosensitive hydrophilic colloid of the support interface, the silver halide photographic light-sensitive material. When the light is reflected by the surface on which the layer is coated and is incident on the silver halide emulsion layer again, image blurring (halation) may occur and the image quality may be deteriorated. In order to prevent halation, a method of coloring the non-photosensitive hydrophilic colloid layer on the back surface is known. Dyestuffs are usually included in the layers to color these layers. This dye is required to satisfy the following conditions. (1) It has an appropriate spectral absorption according to the purpose of use. (2) Photochemically inactive. In other words, it should not adversely affect the performance of the silver halide photographic emulsion layer in a chemical sense, such as reduction in sensitivity, latent image regression, or fog. (3) No detrimental residual color is left on the photographic post-processing photosensitive material by being decolorized or dissolved and removed in the course of development processing. As a method of providing a dye layer, there is a method of dissolving a soluble dye in a hydrophilic colloid layer, which is disclosed in British Patent No. 1,41.
4,456, 1,477,638 and 1,47
No. 7,639. The aforementioned Japanese Patent Application No. 3-14
The silver halide photographic light-sensitive material prepared by the method described in No. 5168 does not substantially permeate the processing solution into the photographic layer on the back surface during the development processing. There is a problem that is not decolorized. Therefore, a means for reducing the dry load and carryover without such inconvenience has been desired.

[0004]

SUMMARY OF THE INVENTION A first object of the present invention is to provide a silver halide photographic light-sensitive material which has a reduced drying load and carry-over amount during development processing and which has a high image quality. The second object of the present invention is to provide a silver halide photographic light-sensitive material having improved curl.

[0005]

The above object is to have at least one silver halide emulsion layer having a hydrophilic colloid as a binder on one surface (A surface) of the support, and the opposite surface (B). In a silver halide photographic light-sensitive material having at least one layer of non-photosensitive hydrophilic colloid on the (side), the hydrophilic colloid binder ratio of the B side and the A side is 0.3 or more by weight, and the step of washing with water during development processing The water content of the B side after the end is 0.2 g or less per 1 g of the hydrophilic colloid binder,
Further, it was achieved by a silver halide photographic light-sensitive material characterized in that it has a layer which is substantially decolorized by development processing on the A side.

DETAILED DESCRIPTION OF THE INVENTION First, the non-photosensitive hydrophilic colloid layer of the present invention (hereinafter referred to as a back layer) will be described. The back layer of the present invention is a layer using a hydrophilic colloid as a binder. As the hydrophilic colloid used for the back layer, a binder for the photographic layer coated with the silver halide emulsion layer is used from the viewpoint of curling. It is preferable that the moisture absorption rate and the moisture absorption rate are close to each other. The most preferable hydrophilic colloid used for the binder of the back layer of the present invention is gelatin. As the gelatin, so-called lime-processed gelatin, acid-processed gelatin, enzyme-processed gelatin, gelatin derivatives and modified gelatin, which are generally used in the art, can be used. Among these gelatins, lime-processed gelatin and acid-processed gelatin are most preferably used.

As hydrophilic colloids other than gelatin, colloidal albumin, proteins such as casein, agar, sugar alginates, sugar derivatives such as starch derivatives, cellulose compounds such as carboxymethyl cellulose and hydroxymethyl cellulose, polyvinyl alcohol, poly-N.
-Synthetic hydrophilic compounds such as vinylpyrrolidone and polyacrylamide can be cited. In the case of a synthetic hydrophilic compound, other components may be copolymerized, but if the hydrophobic copolymer component is too much, the moisture absorption amount and the moisture absorption rate of the back layer become small, which is not suitable from the viewpoint of curling. These hydrophilic colloids may be used alone or in combination of two or more.

In the back layer of the present invention, other than the binder,
A photographic additive such as a matting agent, a surfactant, a dye, a crosslinking agent, a thickener, a preservative, a UV absorber, and inorganic fine particles such as colloidal silica may be added. Regarding these additives, for example, the description in Research Disclosure Vol. 176, Item 17643 (December 1978) can be referred to.

A polymer latex may be further added to the back layer of the present invention. The polymer latex used in the present invention is an aqueous dispersion of a water-insoluble polymer having an average particle size of 20 μm to 200 μm, and the preferable amount thereof is 0.01 to 1.0 in terms of dry weight ratio to 1.0 of the binder, and particularly preferable. Is 0.1 to 0.8. Preferred examples of the polymer latex used in the present invention have acrylic acid alkyl ester, hydroxyalkyl ester or glycidyl ester, or methacrylic acid alkyl ester, hydroxyalkyl ester or glycidyl ester as a monomer unit, and have an average molecular weight of 10 It is a polymer of 10,000 or more, particularly preferably 300,000 to 500,000, and a specific example is represented by the following formula.

[0010]

[Chemical 1]

The back layer of the present invention may be one layer or two or more layers. The thickness of the back layer of the present invention is not particularly limited, but from the viewpoint of curling, it is preferably about 0.2 μ to 20 μ, and particularly preferably 0.5 μ to 10 μ. If the back layer consists of two or more layers, add the sum of the thicknesses of all back layers,
The thickness of the back layer of the silver halide photographic light-sensitive material of the present invention.

The method for applying the back layer of the present invention is not particularly limited. Conventionally known methods for coating a hydrophilic colloid layer of a silver halide photographic light-sensitive material can be used. For example, dip coating method, air knife coating method, curtain coating method, roller coating method, wire bar coating method, gravure coating method, or US Pat.

The multilayer simultaneous coating method described in No. 508947 and No. 2761791 can be used.

The silver halide photographic light-sensitive material of the present invention has a water content of 0.2 g or less per 1 g of hydrophilic colloid after the completion of the washing step during development. There is no limitation on the means for controlling the water content to 0.2 g or less, but the method of providing a hydrophobic polymer layer described later on the non-photosensitive hydrophilic colloid layer (back layer) is most preferable.

Subsequently, a hydrophobic polymer layer (polymer layer)
I will describe. The water content of surface B of the silver halide photographic light-sensitive material of the present invention at the end of the washing step can be controlled to 0.2 g or less per 1 g of the hydrocolloid due to this polymer layer. As the binder for the polymer layer, a hydrophobic polymer is used to prevent the back layer from swelling in the treatment liquid. There are no restrictions on the material as long as these conditions are met. Specific examples of the binder for the polymer layer include polyethylene,
Fluorine resin such as polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polyacrylonitrile, polyvinyl acetate, urethane resin, urea resin, melamine resin, phenol resin, epoxy resin, tetrafluoroethylene, polyvinylidene fluoride, butadiene rubber,

Further, as a binder for the polymer layer, a homopolymer composed of one kind of monomer or a copolymer composed of two or more kinds of monomers may be used. These may be used alone or in combination of two or more.

In the polymer layer of the present invention, a photographic additive such as a matting agent, a surfactant, a dye, a slipping agent, a cross-linking agent, a thickener, a UV absorber, and inorganic fine particles such as colloidal silica may be added, if necessary.

The description in item 43 (December 1978) can be referred to.

The polymer layer of the present invention may be one layer or two or more layers. The thickness of the polymer layer of the present invention is not particularly limited. However, if the thickness of the polymer layer is too small, the water resistance of the polymer layer will be insufficient and the back layer will swell in the treatment liquid, which is inappropriate. On the contrary, when the thickness of the polymer layer is too large, the water vapor permeability of the polymer layer becomes insufficient, and the moisture absorption / desorption of the hydrophilic colloid layer of the back layer is impeded, resulting in poor curling. Of course, the thickness of the polymer layer also depends on the physical properties of the binder used. Therefore, the polymer layer thickness needs to be determined in consideration of both of them. The preferable thickness of the polymer layer depends on the binder species of the polymer layer, but is 0.05 to 10 μm.
m, more preferably 0.1 to 5 μm. When the polymer layer of the present invention comprises two or more layers, the sum of the thicknesses of all the polymer layers is the thickness of the polymer layer of the silver halide photographic light-sensitive material of the present invention.

The method for applying the polymer layer of the present invention is not particularly limited. After coating and drying the back layer, a polymer layer may be coated on the back layer and then dried, or the back layer and the polymer layer may be simultaneously coated and then dried. The polymer layer may be dissolved in the solvent of the binder of the polymer layer and applied by a solvent system, or may be applied by hydrogen using an aqueous dispersion of the polymer.
