Abstract
Abstract A color photographic light-sensitive material having at least one silver halide photographic emulsion layer containing a hydrophobic coupler, in which the color photographic material additionally contains both a polymer having a recurring unit represented by the following general formula (I): ##STR1## wherein R 1 represents a hydrogen atom or a lower alkyl group and R 2 and R 3 each represents a hydrogen atom, an aliphatic hydrocarbon group, an aromatic hydrocarbon group, an alkyl-substituted amino group or an aryl-substituted amino group, with the proviso that both of R 2 and R 3 are not simultaneously hydrogen atoms, the total number of carbon atoms in R 2 and R 3 is 4 to 12, R 2 and R 3 do not contain an acidic group, and R 2 and R 3 can combine to form a ring; And a polymer having a recurring unit represented by the following general formula (II); ##STR2## wherein R 4 has the same meaning as R 1 ; and Q represents (1) --(CH 2 ) p OH, wherein p represents 0 or 1, ##STR3## wherein q represents an integer of 2 to 4, ##STR4## wherein R 5 represents an alkyl group; and R 6 represents a hydrogen atom or an alkyl group, ##STR5## wherein Z 1 represents the atoms necessary to form a lactam ring, an oxazolidone ring or a pyridone ring, or ##STR6## wherein Z 2 represents the atoms necessary to form a morpholine ring.
