Abstract
A tocopherol derivative represented by the general formula, ##STR1## wherein R, R.sub.1 and R.sub.2 represent individually a hydrogen atom or a methyl group; and R.sub.3 represents a straight chain or branched-chain alkyl group having 1 to 18 carbon atoms, or a substituted or unsubstituted aryl group, is incorporated as a light-fading stabilizer into the photosensitive layer of a color photographic lightsensitive material, whereby the photographic material can be prevented not only from fading and discoloration of the finally obtained color image and from discoloration of the non-color-developed portion, but also from formation of fog. Furthermore, the said stabilizer itself is excellent in dispersion stability.
