Image forming process.

摘要

A color image is formed in an image forming reaction system comprising a photographic heat-developable silver halide lipht-sensrtive material by reacting a difficultly soluble metal compound, for example, calcium carbonate with a compound capable of water-mediated complexing reaction with the metsl ion of the difficultly soluble metal compound and having an organic base, for example, guanidine oxalate in the presence of water to increase the pH of the system.
