Multilayer color photographic sensitive silver halide material

Abstract

Abstract PURPOSE:To enhance the color developing property and color balance by adding couplers selected from 3 groups of couplers to the blue-, gree- and red-sensitive layers, respectively. CONSTITUTION:A multilayer color photographic sensitive silver halide material is manufactured by adding couplers selected from groups of couplers represented by formulaeI, II, III[where each of R1 and R2 is H, halogen or 1-4C alkoxy, R3 is alkyl, arylcarboxylic ester or the like, R4 is formula IV (each of R41 and R45 is H, acyl or the like), R6 is aryl or a heterocyclic residue, R7 is H, R8 is 1-20C alkylene, and R9 is alkoxy or the like]to blue-, green- and red-sensitive layers, respectively. Couplers of formulaeI, II, III may be arbitrarily selected and added to the sensitive layers.
