Color photographic recording material containing as cyan correction dyes, azomethine dyes corresponding to the general formula IV or V ##STR1## is distinguished from materials containing the cyan correction dyes hitherto used by its increased stability of latent image nuclei when stored under tropical conditions (35.degree. C. at 90% relative humidity). In formulae IV and V, R.sub.1 and R.sub.2 denote H, optionally substitued C.sub.1 -C.sub.4 -alkyl, C.sub.6 -C.sub.10 -aryl and C.sub.1 -C.sub.3 -alkoxy, R.sub.3 denotes H, optionally substituted C.sub.1 -C.sub.4 -alkyl, C.sub.6 -C.sub.10 -aryl and C.sub.1 -C.sub.3 -alkoxy nd halogen, R.sub.4 denotes H, optionally substituted C.sub.1 -C.sub.4 -alkyl and C.sub.1 -C.sub.3 -alkoxy, CN, halogen, SO.sub.2 R.sub.7, COOR.sub.7, SO.sub.2 OR.sub.7, COR.sub.7, SO.sub.2 NR.sub.7 R.sub.8 and CONR.sub.7 R.sub.8, R.sub.5 denotes NHCOR.sub.9, NHCOOR.sub.9, NHSO.sub.2 R.sub.9 and NHPO(R.sub.9).sub.2, R.sub.6 denotes CON(R.sub.9).sub.2, NHCOR.sub.9, NHCOOR.sub.9, NHSO.sub.2 R.sub.9, NHCON(Rphd 9).sub.2 and NHSO.sub.2 N(R.sub.9).sub.2, R.sub.7 denotes optionally substituted C.sub.1 -C.sub.4 -alkyl and C.sub.6 -C.sub.10 -aryl, R.sub.8 denotes H and R.sub.7, R.sub.7 and R.sub.8 may form a five-membered or six-membered, optionally substituted ring, R.sub.9 denotes H, optionally substituted C.sub.1 -C.sub.4 -alkyl, C.sub.5 -C.sub.10 -cycloalkyl, C.sub.2 -C.sub.6 -alkenyl, C.sub.2 -C.sub.6 -alkinyl, C.sub.6 -C.sub.10 -aryl, C.sub.5 -C.sub.10 -heteroaryl or heteroalkyl and C.sub.1 -C.sub.3 -alkoxy, Ballast denotes conventional ballast groups and n stands for 1 or 2.
Color photographic recording material having a layer support and at least three light-sensitive silver halide emulsion layers differing in their spectral sensitivity applied to said layer support, which silver halide emulsion layers are spectrally associated with, respectively, a cyan coupler, a magenta coupler and a yellow coupler, characterised in that the colour photographic recording material contains, as cyan correction dyes, azomethine dyes corresponding to the general formula (IV) ##STR45## wherein R.sub.1 and R.sub.2 denote H, and optionally substituted C.sub.1 -C.sub.4 -alkyl, C.sub.6 -C.sub.10 -aryl and C.sub.1 -C.sub.3 -alkoxy,
Colour photographic recording material according to claim 1, characterized in that the cyan correction dyes IV are obtained by oxidative coupling of p-phenylenediamine derivatives corresponding to the general formula (I) ##STR46## with cyan couplers of the general formula (II) ##STR47## in which the substituents R.sub.1 to R.sub.4, n and Ballast have the meanings indicated in claim 4, and X.sub.1 denotes H, F, Cl and optionally substituted C.sub.1 -C.sub.4 -alkoxy.
