PURPOSE:To raise the fixing sensitivity, preservability and stability of the titled member by forming a layer contg. a Co complex, a photoreducing agent and a hydrogen donor, a layer contg. a Co complex and a binder, and a layer contg. a photooxidizing agent, a coupler and a coloring accelerator on a support in order. CONSTITUTION:A dispersion contg. a Co (III) complex, a photoreducing agent and a hydrogen donor or further contg. a binder is coated onto a support such as paper or a film and dried to form the 1st layer which is a visible light sensitive layer. A dispersion contg. a Co (III) complex and a binder is coated onto the 1st layer and dried to form the 2nd layer which is an intermediate layer, and then a dispersion contg. a photooxidizing agent, a coupler which colors by oxidation and a coloring accelerating acid or further contg. a binder, a photoreducing agent and a hydrogen donor is coated onto the 2nd layer and dried to form the 3rd layer which is an ultraviolet sensitive layer. Thus, the titled recording member is obtd. As the Co (III) complex, a substance which produces a basic substance such a NH3 by heat reduction is used. |
