Title:
SILVER HALIDE COLOR PHOTOGRAPHIC SENSITIVE MATERIAL
Document Type and Number:
Japanese Patent JPS5942541
Kind Code:
A
Abstract:

PURPOSE: To improve storage stability of a dye image, by forming a red sensitive silver halide emulsion layer contg. a specified cyan ccoupler, and a green sensitive silver halide emulsion layer contg. a specified magenta coupler and a specified compd. on a reflective support.

CONSTITUTION: The red sensitive and green sensitive silver halide emulsion layers are formed on the reflective support, and the former layer contains a cyan coupler represented by formula I in which R is alkyl, and Z is H or a group releasable upon coupling with the oxidized product of a color developing agent, and the latter layer contains a magenta coupler having formula II and compounds (fading preventing agent) represented by formula IIIaWIIIc. In these formulae, Q1 is halogen 1W20C alkyloxy; Q2 is sulfamoyl or the like; R1, R1', R3, R3', R5 are each H, an aliphatic or aromatic group, or the like; and R2, R4, R4', R6, R7 are each halogen or a monovalent org. group.
