The antistatic properties of a photographic light-sensitive member is improved by adding to a surface protective layer a polymer or copolymer having a repeating unit represented by the formula (I) ##STR1## wherein R.sub.1 represents hydrogen or a methyl group, A represents a --COO-- or --CONH-- group, and B represents ##STR2## wherein R.sub.2 and R.sub.3 represent an alkyl group containing from 1 to 6 carbon atoms; R.sub.4 represents hydrogen or a methyl group; R.sub.5 represents an alkyl group containing from 1 to 3 carbon atoms; p is an integer of 2 to 6, q, when R.sub.4 is hydrogen, is an integer of from 1 to 4, and when R.sub.4 is a methyl group, is 1; and D represents a --COO or --SO.sub.3 group.
