ABSTRACT:
A silver halide color photographic material comprising (1) at least one coupler and (2) at least one compound represented by formula (I) ##STR1## wherein EAG represents a group capable of accepting an electron from a reducing substance; R.sup.1 and R.sup.2 each represents a chemical bond or a divalent substituent, or R.sup.1 and R.sup.2 are linked together to form a cyclic structure when linked with (Time).sub.t PUG; or R.sup.1 and R.sup.2 each represents a substituent, or R.sup.1 and R.sup.2 are linked together to form a cyclic structure when not linked with (Time).sub.t PUG; Time represents a group capable of releasing PUG, which is released by the cleavage of the single bond between the oxygen atom and the nitrogen atom in the compound; t represents 0 or 1; PUG represents a photographically useful group; and the dotted lines mean that at least one of them forms a chemical bond, and a method for forming an image using the material.
