摘要:
A silver halide photographic light-sensitive material comprising at least one type of cyan dye-forming coupler represented by formula (I) below and at least one type of difficulty water-soluble epoxy represented by formula (II) below: ##STR1## wherein R.sub.1 represents an alkyl group having at least 7 carbon atoms, R.sub.2 represents an alkyl group with 2 to 15 carbon atoms, L represents a simple linkage or a bivalent linking group, Z represents a hydrogen atom, or a group or atom which can be released at the time of the coupling with the developing agent, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 each represents a hydrogen atom, an aliphatic group, an aliphatic oxycarbonyl group, an aromatic oxycarbonyl group or a carbamoyl group, provided that R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are not all hydrogen atoms, and the total number of carbon atoms thereof is from 8 to 60, and in formula (II), a 5- to 7-membered ring may be formed with R.sub.3 and R.sub.4 or R.sub.3 and R.sub.5, respectively.
