发明名称 Silver halide light-sensitive color photographic material
摘要 A silver halide light-sensitive color photographic materials is disclosed. The material comprises a compound which releases, upon reaction with an oxidation product of a color developing agent, a 2-mercapto-1,3,4-oxadiazole derivative represented by formula I: <IMAGE> I wherein L1 represents a linkage or a divalent linking group; R1 represents an alkyl group, an aryl group or a heterocyclic group; R2 represents a hydrogen atom or a substituent; n represents an integer of one, two or three; and m represents an integer of zero, one or two, provided that sum of m and n is three. The color photographic material produces a dye image having enhanced image-sharpness, showing large inter-image effect with reduced reduction of gamma in the layer, to which the coupler is incorporated and having improved stability with the lapse of time during storage.
