Abstract (en)

[origin: EP0385383A2] A method which comprises the steps of: providing a heat-processible color photosensitive material that has at least a light-sensitive silver halide, a reducing agent, a binder and a dye-providing material on a support, which dye-providing material contains either a dye portion represented by the following general formula (1) or a dye portion represented by the following general formula (2) or both; performing imagewise exposure on said photosensitive material; subsequent to or simultaneously with the imagewise exposure, thermally developing said photosensitive material in close contact with an image-receiving material; transferring onto said image-receiving material all or part of the diffusible dye containing said dye portion which is formed from said dye-providing material as a function of development; during or after the transfer, chelating part or all of the diffusible dye with a metal to thereby form an image of the chelated dye in said image-receiving material: <CHEM> where X represent the atomic group necessary to form an aromatic nitrogenous heterocyclic ring; R1 is a hydrogen atom, a halogen atom or a monovalent organic group; m is an integer of 0 or 1 - 3, provided that when m is 2 or 3, R1 may be the same or different; Y is a hydroxyl group or a group <CHEM> (where R and R7 each represents a hydrogen atom or an optionally substituted alkyl group); and R<2>, R<3>, R<4> and R<5> each represents a hydrogen atom, a halogen atom, or a monovalent organic group.
