    摘要: A silver halide photographic light-sensitive material containing a novel cyan dye forming coupler is disclosed. The cyan dye forming coupler is represented by the following formula. ##STR1## In the formula R.sub.1 and R.sub.2 are each a substituent, and X is a group capable of being splitted off from the coupler residue upon reaction of the coupler residue with the oxydized product of a color developing agent; and the total number of carbon atoms contained in the groups represented by R.sub.1, R.sub.2 and X is from 8 to 50. The spectral absorption characteristics of cyan dye images formed by the coupler of the invention are so sharp and steep that color reproduction can be achieved very advantageously.
