Colour photographic recording material with a coupler liberating a photographically useful compound.

摘要

High edge effects and interimage effects are obtained when DIR couplers of formula I are used in color photographic silver halide materials. I In Formula I, R1 denotes alkyl, for example C4H9-t, aryl, for example p-alkoxyphenyl, NH-aryl or NH-NH-R3; R2 denotes H, halogen, e.g. chlorine, alkoxy, alkylthio or NH-R4; R3 and R4 denote acyl; X denotes the residue of a photographically active compound containing a monocyclic 1,2,3- or 1,2,4-triazole ring, TIME denotes a linking member and n denotes 0 or 1.
