For controlling in a color photographic material the gradation, graininess, sharpness, edge and interimage effect and thus improving the overall color reproduction thioether DIR compounds of the following formula are particularly useful: in which X is a group that if split off together with the sulfur atom forms a diffusing development inhibiting mercaptan, Y represents -O-, or -S-, Z represents the ring members completing a 6-membered heterocyclic ring, R7 is an aliphatic, araliphatic or aromatic hydrocarbon group, a heterocyclic group or acyl, and R2 is the same as R1 or hydrogen.
