| Abstract | A colour photographic material having a yellow filter layer containing at least one decolourisable dye or dye to be able to be rinsed out of the material of the formula (I) in which R1 and R2 mutually independently mean a substituted or unsubstituted alkyl group, R3 means a hydrogen or halogen atom, an alkyl or alkoxy group R4 means a hydrogen atom, an alkyl or cyano group, R5 means a dissociable group having a pKa value of between 4 and 11 and X means an oxygen or sulphur atom, is distinguished in that the dyes are non-diffusible and completely decolourisable and do not impair the properties of the silver halide emulsions. |
