A color photographic print material which contains a cyan coupler of the formulain whichR<1 >means a hydrogen atom or an alkyl group,R<2 >means OR<3 >or NR<4>R<5>,R<3 >means an unsubstituted or substituted alkyl group with 1 to 6 C atoms,R<4 >means an unsubstituted or substituted alkyl group with 1 to 6 C atoms,R<5 >means a hydrogen atom or an unsubstituted or substituted alkyl group with 1 to 6 C atoms,R<6 >means an unsubstituted or substituted alkyl group andZ means a hydrogen atom or a group eliminable under the conditions of chromogenic development,wherein the total number of the C atoms of the alkyl groups R<3 >to R<6 >in a coupler molecule is 8 to 18,is simultaneously distinguished by good light and dark stability as well as by good color reproduction. The couplers furthermore exhibit very good solubility in conventional coupler solvents.
