Abstract
PURPOSE:To form the color image of the titled material by dry-processing with heat by composing a dye providing substance of a compd. having a group capable of allowing a substitution or an addition reaction with a nucleophilic reagent. CONSTITUTION:The titled material comprises at least one of a photosensitive silver halide, a reducing agent, a binder and the dye providing substance which are mounted on a supporting body, and the dye providing substance is composed of the compd. having the group capable of allowing the substitution or the addition reaction with the nucleophilic reagent. The color impurity of the titled material caused by diffusion, etc., is prevented by incorporating the dye providing substance in the titled material. Thus, the titled material with the excellent color purity and the improved image density and fogging, is obtd.
