ABSTRACT:
A method for forming a dye image with high contrast is provided, wherein a heat-processable light-sensitive material comprising a support having thereon a non-light-sensitive layer and a light-sensitive layer containing a light-sensitive silver halide and a dye-providing material capable of releasing or forming a diffusible dye upon heat development is subjected to heat development to release or form the diffusible dye, which is transferred to a dye-receiving material having a dye-receiving layer to form a dye image on the dye-receiving layer, wherein the heat development or the transfer of the dye is carried out in the presence of a compounds represented by formula 1 or 2 and a compound represented by formula 3 or 4,
