摘要： PURPOSE:To increase effective reducing width and to prevent the generation of residue by processing the silver image obtd. by exposing and developing of a silver halide photosensitive material with a ceric salt reducer. CONSTITUTION:The silver image formed by exposing and developing the silver halide photosensitive material is reduced by using the reducer consisting essentially of the ceric salt. Such reducing is executed in the presence of the compd. expressed by formula I (M is H, alkali metallic atom, -NH4, R is H, alkyl, SO3M , COOM , R is -SO3M , -COOM , -OH where M is synonymous with M, n is 1-6) or the formula IIA-(CH2)n-SM (M is the group of formula III, R is H, alkyl, etc. A is -OH, -SO3M , -NR3R4, M is H or alkaline metallic atom, X is halogen atom, etc., n is 2-5). The above-mentioned compd. may be incorporated into the reducer or be made present in the previous bath prior to the reducing process. The area of the silver image is thus decreased while the decrease in the density of the silver image is suppressed.

摘要： PURPOSE: To improve the reducibility of a photosensitive silver halide material for a photomechanical process without increasing the amount of silver coated by making the dissolution time of the nonphotosensitive upper layer longer than that of the photosensitive silver halide emulsion layer, and incorporating starch or a specified polysaccharide into the emulsion.
CONSTITUTION: The degree of reduction in the area of dots before and after processing in a photomechanical process is expressed by the width of reduction, and the reducibility of a photosensitive silver halide material is improved in accordance with increase in the width of reduction. In order to improve the reducibility, the nonphotosensitive upper layer on the silver halide emulsion layer is hardened to a higher degree than the emulsion layer to make the dissolution time of the upper layer in 0.2N NaOH soln. at 75°C longer than that of the emulsion layer by ≥50sec. Starch, hydrolyzed starch, modified starch such as a starch deriv. or a polysaccharide such as dextran prepd. by the microbiological fermentation of starch is incorporated into the emulsion layer. Thus, a photosensitive material for a photomechanical process reducible in a moderate time and capable of increasing the width of reduction is obtd.
