Heat-developable color photo-sensitive material with polymeric coupler

摘要

In a heat-developable color photo-sensitive material comprising a support bearing thereon a photographic component layer containing at least a photo-sensitive silver halide, a reducing agent, a binder and a dye-providing material; said heat-developable photo-sensitive material characterized in that at least one of said dye-providing materials is a polymer having a repetition unit being derived from a monomer Formula [I] below: <IMAGE> Formula [I] wherein , Q represents an ethylene unsaturated group or a group having an ethylene unsaturated group; Z represents a group of atoms required for forming a nitrogen-containing heterocyclic residual group in which a polymerizable ethylene unsaturated bonding may also be incorporated into the heterocyclic ring, together with a nitrogen atom; R1 represents an alkyl, aryl, alkylamino, anilino, acylamino or ureido group; Ar represents an aryl group or a heterocyclic residual group; and n is an integer of zero or one.
