A colour photographic silver halide material with a support, at least one silver halide emulsion layer and at least one non-light sensitive layer applied thereto, wherein the silver halide emulsion layer contains at least one colour coupler, and wherein the silver halide emulsion layer or the non-light sensitive layer contains a compound of the formula (I) ##STR1## in which R.sub.1, R.sub.2 and R.sub.3 mean hydrogen or an organic residue and n means 0 or an integer from 1 to 4 or R.sub.1 and R.sub.2 together, R.sub.1 and an adjacent residue R.sub.3 together or two adjacent residues R.sub.3 together form a carbocyclic or heterocyclic ring with 5 to 7 ring atoms or R.sub.1, R.sub.2 or R.sub.3 mean a bridging member by means of which two compounds of the formula (I) are attached together or R.sub.1, R.sub.2 or R.sub.3 are attached to a polymer via a bridging member, wherein at least one of the substituents R.sub.1, R.sub.2 and R.sub.3 is an organic residue, is distinguished by improved grain.
A color photographic silver halide material which comprises a transparent support, at least one silver halide emulsion layer and at least one non-light sensitive layer applied thereto, wherein the silver halide emulsion layer contains at least one color coupler and a silver halide consisting of 0 to 15 mol- % silver iodide, 0 to 20 mol- % of silver chloride and 65 to 100 mol- % of silver bromide, and wherein the silver emulsion layer or the non-light sensitive layer contains a compound of the formula (I)
A color photographic silver halide material which comprises a support, at least one silver halide emulsion layer and at least one non-light sensitive layer applied thereto, wherein the silver halide emulsion layer contains at least one color coupler, and wherein the silver emulsion layer or the non-light sensitive layer contains a compound selected from the group consisting of:
A color photographic silver halide material which comprises a support, at least one silver halide emulsion layer and at least one non-light sensitive layer applied thereto, wherein the silver halide emulsion layer contains at least one color coupler, and wherein the silver emulsion layer or the non-light sensitive layer contains a compound of the formula (II) ##STR14## wherein R.sub.2 is C.sub.17 H.sub.33, C.sub.13 H.sub.27, C.sub.17 H.sub.31, C.sub.6 H.sub.13 S, C.sub.8 H.sub.17 S, C.sub.10 H.sub.21 S, C.sub.12 H.sub.25 S, C.sub.13 H.sub.27 S, C.sub.14 H.sub.29 S, C.sub.16 H.sub.33 S, C.sub.18 H.sub.37 S, CH(CH.sub.3)CO.sub.2 C.sub.12 H.sub.25, CH.sub.2 CH.sub.2 SC.sub.18 H.sub.37, CH.sub.2 SC.sub.12 H.sub.25, or 2--C.sub.10 H.sub.21 S-phenyl.
