摘要： PROBLEM TO BE SOLVED: To prevent sweating and to improve adhesion property of a photosensitive layer by incorporating a specified compd. and incorporating a polymer coupler produced from specified monomers into a silver halide emulsion layer. SOLUTION: This photosensitive material has red, green and blue photosensitive silver halide emulsion layers and a invisible ray-sensitive silver halide emulsion layer, and contains at least one kind of compd. expressed by the formula I or II. At least one silver halide emulsion layer contains at least one kind of polymer coupler prepared from monomers expressed by the formula III. In the formulae I, II, each Z11, Z12, Z21, Z22 represents a group of nonmetal atoms necessary to form a five or six-member monocycle or condensed nitrogen- contg. heterocycle, each R11, R12, R21, R22 is an aliphatic group, each R13 to R17 and R23 to R29 is a hydrogen atom, alkyl group or the like. In the formula III, R1 is a hydrogen atom, 1-4C substd. or unsubstd. alkyl group, L1 is -CON(R2) or the like, and L2 is a connecting group which bonds L1 and Q.

摘要： PROBLEM TO BE SOLVED: To provide the photosensitive maternal high in sensitivity and superior in graininess and sharpness by incorporating a coupler inconstant in coupling speed. SOLUTION: This silver halide color photographic sensitive material contains the inconstant speed coupler substantially different in the coupling speed in the early stage from that in a later stage in a developing process and satisfying the following relationship. The coupling speed obtained by a relative estimation method of the coupling speed using a citrazinic acid is >=2.5 (Ra) in the early stage of development and a ratio of later speed (Rb) to the early speed (Ra) is
