Heat development of silver halide element with redox dye releaser and stabilizer

Abstract

A process for forming an image is described, comprising heating a light-sensitive material in a substantially water-free condition to form a mobile dye in an image pattern, said material having a support bearing thereon light-sensitive silver halide, a binder, and a dye-releasing redox compound capable of imagewise reducing the silver halide and releasing a hydrophilic dye on reaction with said silver halide when heated, after or simultaneously with imagewise exposure, in the presence of a compound having a melting point below 60.degree. C. represented by formula (A) ##STR1## wherein p is an integer of 1 to 5 and q is an integer of 1 to 4, provided that p+q is 6 or less; R represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, an alkoxy group, an aryloxy group, an aralkyl group, an acyl group, an acylamino group, an alkylsulfonylamino group, an alkoxyalkyl group, an aryloxyalkyl group, an acyloxy group, an acyloxyalkyl group, a carbamoyl group, an N-substituted carbamoyl group, a ureido group, an N-substituted ureido group, an alkylamino group, a dialkylamino group, an arylamino group, a halogen atom, a hydroxy group, a carboxy group, a nitro group, a cyano group, an alkyoxycarbonyl group, an aryloxycarbonyl group, or a cycloalkyloxycarbonyl group; and R.sup.1 represents an alkyl group, an alkenyl group, a cycloalkyl group, an alkenyl group, a cycloalkyl group or an aryl group. Also, a heat developable light-sensitive material is disclosed.
