Title:
SILVER HALIDE COLOR PHOTOGRAPHIC SENSITIVE MATERIAL AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JPH103148
Kind Code:
A
Abstract:

To obtain rapid processing aptitude and short time exposure aptitude and to reduce deterioration of sensitization and pressure sensitization by enhancing the silver chloride content and incorporating a specified amount of iron ions and a specified water-soluble compound.

At least one of silver halide emulsion layers contains silver halide grains having a silver chloride content of ≥95mol% and containing iron ions in an amount of 10-7-10-3mol per 1mol of silver halide and an iron ion concentration in the surface region of each grain occupying ≤50% of the grain volume of each grain is ten times more than that of the other region, and the silver halide emulsion layer contains the water-soluble compound represented by the formula in which each of X1 and X2 is H or a halogen atom or hydroxyl group or the like and one of both must be H atom; each of R11 and R12 is H atom or an optional substituent; M is H or a univalent alkali metal atom; each of R13 and R14 is H atom or an alkyl group; and R15 is an alkyl or aryl group.
