BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-sensitive material for scanners, and more particularly to a silver halide photographic light-sensitive material suitable for a scanner using an LED as a light source.

0002

BACKGROUND OF THE INVENTION In recent years, scanners have become widespread in the printing and plate making industry. Various laser light sources such as argon, helium/neon, and semiconductor are used as light sources for scanners, but LEDs have also come to be used as a powerful light source.

[0003] There is also a strong desire for faster processing.
There is a strong need for the development of photosensitive materials suitable for LED light source scanners that can provide high contrast and rapid processing.

[0004] As a method for obtaining high contrast, a method using a hydrazine derivative is known, but when a hydrazine derivative is used, failures called so-called black spots are likely to occur. That is, since the image forming method using a hydrazine derivative strongly promotes contagious development, when photographing a character document with low contrast, a problem arises in that even the thin white area becomes black, the characters are crushed, and the characters become illegible.

In addition, in order to be compatible with LED light sources, it is necessary to have a panchromatic wavelength range, but with such photosensitive materials, the stability of the coating liquid is poor, and the stability over time after coating is poor. There is a problem.

[0006]

[Object of the Invention] In order to solve the above-mentioned problems, the object of the present invention is to provide an LED scanner that is suitable for LED scanners, has high sensitivity, high contrast, less occurrence of black spots, and good line width and halftone dot reproducibility. It is an object of the present invention to provide a silver halide photographic material that has good coating solution stagnation properties and stability over time after coating and can be rapidly processed.

The silver halide grains according to the present invention may be of a single shape or may be a mixture of grains of various shapes.

Although emulsions having any grain size distribution may be used and several types of emulsions having different grain size distributions may be mixed, monodisperse emulsions are preferred in the present invention.

This is the diameter when the projected image is converted into a circular image of the circumferential area. The particle size can be obtained, for example, by photographing the particles with an electron microscope at a magnification of 10,000 to 50,000 times, and actually measuring the particle diameter or projected area on the print. (The number of grains to be measured is assumed to be 1000 or more indiscriminately.)

Furthermore, if necessary, a silver halide solvent such as a thioether, or a crystal habit control agent such as a mercapto group-containing compound or a sensitizing dye may be used.

Example 5 In Example 1, the stability over time of each sample was evaluated by the following method. That is, after conditioning each sample at 23°C and 48% relative humidity, polyvinyl acetate (thickness 100 μm)
The sample was sealed and packaged with a moisture-proof material laminated with , and heat-treated in a thermostat at 55° C. and 50% relative humidity for 72 hours.

When these samples were evaluated in the same manner as in Example 1, it was found that the present invention had good sensitivity, fog, image quality, and black spots, and had little deterioration over time.

[0114]

[Effects of the Invention] The present invention provides high sensitivity, high contrast, less occurrence of black spots, good line width and halftone dot reproducibility, and good coating liquid stagnation properties and stability over time after coating. As a result, it was possible to provide a silver halide photographic material for LED scanners that can be rapidly processed.
