Description

Detailed Description of the Invention (1) Background of the Invention Technical Field The present invention relates to a silver halide photographic material containing a novel polymer latex (hereinafter simply referred to as "latex").

More specifically, the present invention relates to a silver halide photographic light-sensitive material that has improved adhesive strength and decompression speed, and has excellent photographic properties.

Prior art and its problems By incorporating latex into the hydrophilic colloid layer constituting the silver halide photographic light-sensitive material, it is possible to improve the adhesive strength of the hydrophilic colloid layer to the support and the mutual adhesive strength between the layers. The technology to improve the elasticity (dimensional stability) of materials is
This technique is well known to those skilled in the art and is widely practiced.

As such latex, for example, U.S. Patent No. 3
4119] No. 2, No. 3488708, No. 3930
No. 13Q, No. 3929482, JP-A-51-130
No. 217, No. 51-1364] No. 9, Special Publication No. 1973-25
Although various latexes have been proposed, such as in No. 499, they are not necessarily satisfactory.

That is, these conventional latexes are not necessarily stable per se, and many of them cause agglomeration and precipitates or undesirable chemical changes during storage or when added to photographic emulsions.

Moreover, many of these latexes do not have sufficient adhesive strength as described above, or have an adverse effect on photographic performance, causing capri or a decrease in sensitivity.

Furthermore, when attempting to reduce the amount of wood-philic colloid for the purpose of improving dimensional stability, this increases the speed of reduction, especially in photosensitive materials for printing, so latex is added instead. Alternatively, attempts have been made to increase the amount, but a sufficient effect of suppressing the force reduction speed cannot be obtained.

In this case, reduction means, as is well known to those skilled in the art, that after the photosensitive material has been developed, the silver image is oxidized and dissolved using a strong oxidizer solution (for example, ceric sulfate solution). It's a manipulation.

Thus, conventional latex is disadvantageous in some respects.

To explain the shortcomings of conventional latex in more detail, for example, a copolymer latex of acrylic acid ester and vinylidene chloride, as disclosed in Japanese Patent Publication No. 49-25499, has an extremely excellent film adhesive strength. However, the latex itself changes over time, which may affect photographic performance. Also, JP-A-51-130217
The latex disclosed in the above issue has a problem in that a sufficient effect of suppressing the speed of reduction in force cannot be obtained.

TI OBJECTS OF THE INVENTION The main object of the present invention is to solve the various problems that arise when using conventional latex as described above.

More specifically, the purpose of the present invention is to provide a silver halide photographic light-sensitive material using a new latex that is stable, has strong adhesive strength of a hydrophilic colloid layer, has excellent photographic properties, and has a large effect of suppressing the speed of reduction. It is about providing.

Such objects are achieved by the invention described below.

That is, the present invention provides a silver halide photographic material in which a hydrophilic colloid layer including at least one photosensitive silver halide emulsion layer is coated on a support, in which a hydrophilic colloid layer comprising at least one photosensitive silver halide emulsion layer is coated on a support. The silver halide photographic material is characterized in that at least one layer contains one or more polymer latexes represented by the following general formula (1).

Furthermore, R6 may be a hydrogen atom or a monovalent group.

The monovalent group may be an @aqueous group or a hydrophilic group.

Moreover, when n>15 wt%, in the case of a hydrophilic monomer, it tends to become latex, and in the case of a hydrophobic monomer, the hydrophobicity becomes too strong.

The present invention is characterized in that a tertiary copolymer latex represented by the general formula (I) is contained in the wood-philic colloid layer of a silver halide photographic light-sensitive material. Specific examples are described below.

Example 1 Average grain size 0.25. with a composition of 25 mol% silver bromide and 75 mol% silver chloride. A silver chlorobromide emulsion was prepared by the neutral double jet method.

After physical ripening, desalting is carried out by precipitation and washing with water, gelatin is added and redispersed, and sulfur sensitization and gold sensitization are performed by conventional methods. A polyalkylene oxide compound as described in US Pat. No. 3,518,085 was added to finish the emulsion.

The resulting gelatin silver halide emulsion was divided into 8 parts. The exemplary latex of the present invention and the comparative latex were added to each divided portion as shown in Table 1 below (the amount added was 0.7 g as dry weight of latex per 1 g of gelatin), and a coating aid. After preparing a coating solution, it was left to stand at 40°C for 1 hour, and the stability of the coating solution was evaluated.

Next, a hardening agent was added to this coating solution, and it was coated on the undercoated polyethylene terephthalate film base at a concentration of 2.0 g/rn' as gelatin acid, and dried.

A portion of the obtained coated sample was cut into strips and exposed to light using a tungsten lamp through a step tablet to prepare a sample for sensitometry.

The remaining samples included l 7 made with printing lith film.
5 A 1ine/1nch 50% dot flat mesh original was brought into close contact with the original and exposed to light using a tungsten lamp in the same manner to prepare a sample for evaluating the speed of reduction and for evaluating the adhesive strength. The exposure adhesion at this time was adjusted so that a 55% Dot was obtained as a 1-1-1% dot when development was carried out under the conditions described below.

Next, the exposed sample was treated with a Liss developer for printing sensitive materials.
The image was developed using CDL-271 (manufactured by Konishiroku Photo Industry Co., Ltd.) at a solution temperature of 27° C. for 1 minute and 40 seconds, followed by fixing, washing with water, and drying according to conventional methods.

Of these samples, a portion of the two pieces was cut into small pieces and added to the working solution (undiluted solution: water = 1:2) of reducing liquid R-21 (manufactured by Konishiroku Photo Industry Co., Ltd.). It was immersed at regular intervals to reduce the force.

At this time, the time required for the original 55% halftone dot to be reduced to 45% was measured, and the reduction speed was evaluated as 5.

In addition, make a weak cut with a safety razor (only the gelatin layer is cut) on the coated surface of the remaining flat mesh sample.
The adhesion strength of the gelatin emulsion film to the base was evaluated by applying Sellotape on top of the tape and instantly peeling it off.

Table 1 shows the results of the second evaluation.

The evaluation criteria are as follows.

(Coating solution safety) A: No problem at all B: Some aggregates were generated C: A large amount of aggregates were generated (adhesive strength of gelatin film) D: No peeling at all E: The cellophane tape peeled off beyond the adhesive surface A −

As will become clear from Example 2, another drawback was found in Compound Example (a).

Example 2 A coated sample was prepared in exactly the same manner as in Example 1, except that the latex to be added was one that had been left at room temperature for three months after synthesis, and sensitometry was performed in the same manner.

The results are shown in Table 2.
