Abstract
A color photographic silver halide light-sensitive material is described, characterized by containing at least one of the compounds represented by the general formula (I) and their precursors. ##STR1## wherein R represents ##STR2## (wherein R.sub.1 and R.sub.2 are each a hydrogen atom or an alkyl group and may combine with R.sub.3 to form a ring having 5 to 10 carbon atoms, provided that R.sub.1 and R.sub.2 are not hydrogen atoms at the same time, R.sub.3 is a substituted or unsubstituted aryl group, and n is an integer of 1 to 4), and R' has 1 to 20 carbon atoms and represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, or a substituent defined by R as defined above). This light-sensitive material provides color images which are stabilized, i.e., freed of fading and the discoloration of the white ground.
