Abstract

PURPOSE:To provide a high sensitivity and to suppress the generation of fogging during long-term preservation by incorporating photosensitive silver halide particles and internally fogged metal salt particles into a titled material and incorporating a specific compd. therein. CONSTITUTION:This photosensitive material has at least one silver halide photographic emulsion layer on a base. The photosensitive material contains the photosensitive silver halide particles and the internally fogged metal salt particles and contains the compd. expressed by the formula. In the formula, L1-L4 respectively denote a bivalent hydrocarbon group; J1 and J2 respective denote -O-, -COO-, etc.; Y denotes a hydrogen atom., bivalent coupler or amidino group; Z denotes a heterocyclic group; G denotes a sulfonic acid group, carboxyl group, etc.; R<1> and R<2> respectively denote a hydrogen atom., alkyl group, etc.; k, l, m, n denote 0-2 integer; p denotes 0-4 integer; q denotes 1-4 integer; r denotes 1-2 integer. However, m denotes 1-2 integer if G is a carboxyl group and r denotes 2 if Y denotes a bivalent coupler. The generation of the fogging during the long-term preservation is thereby suppressed and the high sensitivity and high contrast are obtd. The color tone of the developed silver is good.
