Abstract
A color-photographic recording material which, in at least one light-sensitive silver halide emulsion layer, an interlayer and/or a protective layer, contains at least one polyalkylpiperidine compound of the formula I ##STR1## as a light stabilizer. Color images obtained by imagewise exposure and development of this color-photographic recording material display good stability to the action of visible and ultra-violet light. With respect to the definitions of the substituents and symbols in formula I, reference is made to the specification.
