Abstract
A heat developable color photographic material is disclosed. The color photographic material is comprised of a support having thereon a light-sensitive mixed crystal silver haloiodide having a silver iodide content of 4 to 40 mole %, a binder and a dye-providing substance capable of providing a mobile dye, when the silver haloiodide is reduced to silver by heating, in chemical relation to the reaction. The color photographic material is capable of producing an image by quick development in a substantially water free state. Even when the color photographic material is used in combination with an organic silver salt it is capable of providing excellent color sensitivity.
