Color photographic recording material containing a coupler which releases a photographically active compound

摘要

Couplers corresponding to formula I below used in multilayer color photographic recording materials are suitable for the release of photographically active compounds. I In formula I above, A represents the residue of a coupler which, as a consequence of a reaction with the oxidation product of a silver halide developer under the photographic development conditions, releases a radical corresponding to the following formula Time represents a bond which, on reaction of the coupler with the oxidation product of a silver halide developer, is released together with the triazole ring attached thereto and, in turn, releases the triazole ring with delay under the development conditions; n=0, 1 or 2; R1 and R2 represent any substituents, provided the compound of formula II (II) as a whole is a photographically active compound after release.
