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 material, and more particularly to a silver halide photographic material suitable for rapid processing.

0002

BACKGROUND OF THE INVENTION In recent years, the consumption of silver halide photographic materials has continued to increase. For this reason, the number of sheets of silver halide photographic light-sensitive materials to be developed has increased, and it is required to speed up the development process, that is, to increase the amount of processing within the same amount of time.

One way to shorten the development processing time (generally consisting of the steps of development, fixing, washing, and drying) is to increase the transportation speed. However, when developing with a roller conveyance automatic developing machine, increasing the roller conveyance speed in an attempt to shorten the development time results in (a) insufficient density (decreased density, sensitivity, and contrast); (b) )Fixing is not done sufficiently (c)Washing of the film is insufficient (
d) Problems such as insufficient drying of the film occur. Insufficient fixing and insufficient water washing cause the color tone to change during film storage, resulting in a decrease in image quality.

[0004] One way to solve these problems is to reduce the amount of gelatin, but films with a small amount of gelatin may be difficult to develop if they rub against each other or if the film is rubbed with other substances. After treatment, abrasion deterioration with a higher concentration than other parts is more likely to occur.

[0005]

[Object of the invention] The object of the present invention is to
To provide a silver halide photographic material that has high density and high sensitivity, is resistant to scratches during processing even when the amount of gelatin is small, and produces little silver sludge.

[0006]

SUMMARY OF THE INVENTION The above object of the present invention is to provide a silver halide photographic material containing at least one layer of a light-sensitive silver halide emulsion, in which an ultraviolet curing agent is added to the emulsion layer and/or other hydrophilic colloid layer. This is achieved by a silver halide photographic material containing at least one type.

[0007] The emulsion layer and/or other hydrophilic colloid layer contains a polymer latex, and the amount of gelatin on the layer side containing the emulsion layer with respect to the support is 2.5
It is preferable that it is less than g/m2.

The present invention will be explained in detail below.

In the present invention, the authors have found that adding an ultraviolet curing agent to the hydrophilic colloid layer is very effective in reducing damage during processing. A normal photosensitive plate-making material for bright room use is exposed to light at a dose of 10 to 100 mJ, but even an ultraviolet curing agent that requires an exposure amount of 1000 mJ or more can be cured in the present invention. This is considered to be due to effects other than curing simply as an ultraviolet curing agent. This effect is effective even when the gelatin content is large, but the effect is great when the gelatin content is 0.5 to 2.5 g/m2 or less.

[0010] In this specification, the preferred amount of the ultraviolet curing agent according to the present invention is preferably 0.1 to 5000 mg per m2, particularly preferably 0.3 to 1.
000mg. The addition position may be at any step, but is preferably after the completion of silver halide grain preparation, particularly preferably after the completion of chemical ripening. Further, it may be added to either a photosensitive layer or a non-photosensitive layer, but it is particularly preferable to add it to a non-photosensitive layer.

The amount of ultraviolet light for curing the ultraviolet curing agent of the present invention is preferably 1 to 10,000 mJ, more preferably 1
~5000mJ.

[0012] Specific examples of the ultraviolet curing agent will be described below, but the present invention is not limited thereto.
