Abstract
Abstract There is disclosed a silver halide light-sensitive photographic material containing a novel coupler represented by the following Formula I: ##STR1## wherein R represents a hydrogen atom or a substituent; X and Y represent independently a hydrogen atom or a group capable of splitting off upon a reaction with an oxidation product of a developing agent; Z represents a benzene ring, a naphthalene ring or a the group of atoms necessary to form a 5 to 7-membered heterocyclic ring; and n represents an integer of 1 or 2.
