Description

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 excellent in ultra-rapid processing suitability (drying property) and free from deterioration of sensitivity and softening.

[0002]

BACKGROUND OF THE INVENTION Recently, in silver halide photographic light-sensitive materials, the demand for rapid processing has become extremely strong.
However, various problems arise due to the rapid processing. For example, the drying may be poor and the conveyance may be poor. Therefore, if you raise the drying temperature in the automatic processor,
The dimensional stability of the film is impaired. Further, although reducing the amount of gelatin, which is a binder generally used in light-sensitive materials, is effective for drying, silver produced by the processing tends to become sludge. Alternatively, if the hardness of gelatin is increased in order to control the water absorption of gelatin, problems such as a decrease in image silver concentration occur.

It is well known to incorporate a polymer latex into a silver halide emulsion layer and a backing layer to improve the physical properties of a light-sensitive material. For example, Research Disclosure 19951, Japanese Patent Publication No. 39-4272, 39-17702,
43-13482, U.S. Pat.Nos. 2376005, 2763625, 2772
No. 166, No. 2852386, No. 2853457, No. 3397988, etc.

However, simply adding a latex dispersion-stabilized with a conventional surfactant cannot suppress the above-mentioned formation of silver sludge and cannot improve the drying property. However, it has been found that the use of gelatin latex can improve the ultra-rapid processability (dryability). (Japanese Patent Application No. 4-53715) However, the use of gelatin latex tends to cause deterioration in sensitivity and softening over time, and there is an urgent need to improve it.

[0005]

SUMMARY OF THE INVENTION With respect to the above problems, the object of the present invention is to improve the drying property without causing the generation of silver sludge and the decrease in concentration even when the rapid processing is carried out, and also to decrease the sensitivity with time and the softening The object is to provide a silver halide photographic light-sensitive material that does not change.

[0006]

The above object of the present invention can be achieved by the following structure or.

In a silver halide photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer on a support, at least one of hydrophilic colloid layers containing the light-sensitive silver halide emulsion layer is gelatin. A silver halide photographic light-sensitive material comprising a stabilized polymer latex and a compound represented by the following general formula (I).

[Chemical 2]

[X and Y represent a hydrogen atom, amino, alkyl, aralkyl, aryl, alkenyl, acylamino or sulfonamide group. The silver halide photographic light-sensitive material according to claim 1, wherein the compound represented by the general formula (I) is added to a layer containing a silver halide emulsion.

The present invention will be described in more detail below.

First, the latex stabilized with gelatin will be described.

In the present invention, the object of the present invention can be achieved by using a latex stabilized with gelatin.

That is, the usual latex is dispersed in water by a surfactant, but the latex that can be used in the present invention is the surface of the polymer latex and / or
Alternatively, the inside is dispersed and stabilized by gelatin. The polymer constituting the latex and gelatin may have some kind of bond. In this case, the polymer and gelatin may be bound directly or may be bound via a crosslinking agent. Therefore, the monomers constituting the latex include carboxyl group, amino group, amide group, epoxy group, hydroxyl group, aldehyde group, oxazoline group, ether group, ester group, methylol group, cyano group, acetyl group, unsaturated carbon bond. It is desirable to include those having a reactive group such as. When a cross-linking agent is used, it is possible to use one that has been used as a usual cross-linking agent for gelatin. For example, an aldehyde-based, glycol-based, triazine-based, epoxy-based, vinyl sulfone-based, oxazoline-based, methacrylic-based, acrylic-based, etc. crosslinking agent can be used.

The gelatin-stabilized latex according to the invention is characterized in that at least part of the polymerisation reaction of the polymer is carried out in a solvent which contains at least gelatin. USP 5026632 discloses a technique for improving pressure resistance by adding particles having a hard shell of gelatin hardened with a cross-linking agent in a layer to polymer particles having a Tg of 25 ° C. or less prepolymerized. There is. Also US
Nos. P4920004 and 4855219 disclose a technique of improving adhesiveness by using as a matting agent, polymer particles which are previously polymerized and covalently bound to gelatin. However, in such particles, the effect of preventing silver sludge, which is the object of the present invention, could not be recognized.

Although USP2852382 describes that a polymer is synthesized in the presence of gelatin, it is intended to be contained in a silver halide emulsion layer of a color photographic light-sensitive material, and the effect of preventing silver sludge as in the present invention can be obtained. I can't.

US Pat. No. 2,787,545 discloses a method of desalting a silver halide emulsion using a graft polymer of gelatin and acrylic acid. Even if such an emulsion is used, the effect of preventing silver sludge as in the present invention can be obtained. I can't. Further, JP-A-59-121327, JP-A-62-115152 and the like describe examples of adding a latex to a non-photosensitive upper layer (protective layer), but the effect of the latex of the present invention cannot be obtained. .

The present inventor has found that, in the course of continuing to study the above problems, the ratio of the addition amount of gelatin and latex at the time of synthesis has a preferable range. The weight ratio of gelatin to polymer at the time of synthesis (finally obtained as latex) is preferably Gel / Poly = 1/100 to 2/1, and particularly preferably 1/50 to 1/2. The effects of the present invention give particularly preferable results when the amount of the polymer component of the latex added is 20% or more based on the gelatin in the layer to which the latex is added.

The addition amount of the polymer is 0.05-5 g / m ^2, particularly preferably 0.1~2.5g / m ^2.

The polymer latex used in the present invention can change the MFT (minimum film forming temperature) depending on the composition of the monomer, but it is particularly effective when the MFT is 60 ° C. or lower, more preferably 50 MFT. It is below ℃.

Furthermore, the present invention has a latex particle size of 0.3 μm.
The following is preferable. It is presumed that the reason why the effect of preventing silver sludge is decreased when the particle size is large is that the packing density is decreased when the particle size is large. A particularly preferred particle size is 0.01 to 0.27 μm.

The composition of the monomer of the polymer latex contained in the photographic light-sensitive material of the present invention is, for example, US Pat. Nos. 2,772,166, 3,325,286 and 3,411,911.

In the present invention, the total amount of the hydrophilic binder on the side having the photosensitive silver halide emulsion layer with respect to the support is
It is particularly effective in cases where it is 2.7 g / m ² or less. Even when the total amount of the hydrophilic binder is 2 g / m ² or more, the latex of the present invention is effective, but the effect of the present invention is to add a hydrophilic colloid such as gelatin to improve the drying property of the light-sensitive material. This is because it prevents silver sludge when it is reduced. Particularly preferred is a case where the total amount of hydrophilic binders on the side having the photosensitive silver halide emulsion layer with respect to the support is 2.5 g / m ² or less.

When the compound of the general formula (I) is used alone, the sensitivity is lowered when the silver halide photographic light-sensitive material is stored with time. However, when used in combination with a gelatin-stabilized polymer latex, not only the decrease in sensitivity is prevented, but there is a tendency to occur when only a gelatin-stabilized polymer is used.

(Developer tank 40 liters) large size (610 x 508 m
The silver concentration in the developer was analyzed when 500 samples of m) were continuously processed at 5 second intervals. One of the five samples was completely blackened and the other four were unexposed.

The replenishment amount was 20 cc for each of the developing solution and the fixing solution.

(Drying property) The above continuous treatment was carried out at 30 ° C. and 80 RH%.
And the drying temperature was 33 ° C.

The dry state immediately after being discharged from the automatic processor was evaluated by touch.

The evaluation rank was 5: good dry condition was obtained to the end 4: poor drying was not more than 5 out of 500 sheets. 3: no defective drying was caused by 10 sheets, but not less than 6 out of 500 sheets. 2) Defects occur in the 4th to 10th sheets 1: Defects occur in the 3rd or less sheet (maximum density Dmax) Density when the maximum density is given by changing the exposure .

The obtained sample was used as an optical densitometer Konica PDA-65.
Concentration is measured with, and the sensitivity of Sample No. 1 at a concentration of 3.0 is 100.
The relative sensitivity is shown, and gamma is displayed with the tangent of the densities of 3.0 and 0.3. A gamma value of less than 6 is unusable, and a gamma value of 6 or more and less than 10 still has insufficient contrast. With a gamma value of 10 or more, the image becomes ultra-high contrast and can be used sufficiently.

From the results shown in Table 1, it can be seen that the samples of the present invention have improved drying properties without causing deterioration of silver sludge, and the sensitivity variation and softening over time have been greatly improved.
