Abstract
A method for forming an image comprising heating a light-sensitive material comprising a support having provided thereon at least a light-sensitive silver halide and a dye developer in the presence of a base and/or a base precursor after or simultaneously with imagewise exposure to imagewise distribute a mobile non-oxidation type dye developer, wherein the dye developer is a compound having a dye moiety having a ballast group which is split off upon heating in the presence of the base and/or base precursor and a developer moiety against the silver halide in one molecule, is disclosed. According to the method of the present invention, images which are improved in image identification and color separation characteristics are obtained by heat development of the light-sensitive material.
Claims10
A method for forming an image comprising heating a light-sensitive material comprising a support having provided thereon at least a light-sensitive silver halide and a dye developer, said dye developer not releasing or forming a dye but developing silver halide to thereby render the dye developer non-diffusible, said heating being in the presence of a base and/or a base precursor after or simultaneously with image exposure to imagewise distribute a mobile non-oxidation type dye developer, wherein the dye developer is a compound having a dye moiety having a ballast group, which ballast group is split off upon heating in the presence of the base and/or base precursor, said dye developer also containing a developer moiety for the silver halide in its molecule, said dye developer being immobilized in said light-sensitive material by developing the silver halide, whereafter said ballast group splits off.
