ABSTRACT:
The invention relates to a color-photographic recording material comprising, on a support, a blue-sensitive, a green-sensitive and/or a red-sensitive silver-halide emulsion layer, a protection layer above the sensitive layers, and, if desired, separation layers between the sensitive layers, where at least one of said layers includes a UV absorber of the formula ##STR1## The stabilizers of the formula (1) or (1a) have good inherent stability and high light absorption; the photographic recording material described has excellent stability of the magenta, cyan and yellow layers.
