Abstract

A heat developing color photosensitive material is disclosed. The material comprises a support having thereon a photosensitive silver halide, a reducing agent and a dye providing substance capable of forming or releasing a dye having maximum absorption in the wavelength region from 400 nm to 700 nm, wherein said support further has thereon an infrared dye providing substance capable of forming or releasing a dye having maximum absorption in the wavelength region longer than 725 nm.
