description	A color photographic silver halide material comprising a support and at least one silver halide emulsion layer which is deposited thereon and which contains at least one color coupler, characterized in that said layer also contains a compound of formula (I) wherein R1 denotes alkyl, aryl, aralkyl or hetaryl, R2 denotes H or R1, or R1 and R2 together denote the remaining members of a heterocyclic ring, R3, R4, independently of each other, denote aryl or hetaryl or together denote the remaining members of a phenanthrene ring which is condensed-on in the 9,10-position, wherein R1 can also be H if R3 and R4 together form a phenanthrene ring, is distinguished by improved granularity.
