Beschreibung
Zusammenfassung:	A color photographic silver halide material having a support, at least one photosensitive silver halide emulsion layer and a polymeric cyan coupler associated with the photosensitive silver halide emulsion layer, which coupler contains polymerised units of the formula (I) in which X means a hydrogen atom or a group eliminable under chromogenic development conditions, R1 means a hydrogen or halogen atom, an optionally substituted alkyl, aryl or acylamino group, R2 means an optionally substituted alkyl, aryl or heterocyclic group and n means a number from 0 to 3, is distinguished by improved stability of the cyan dye.
