Abstract

PURPOSE:To prevent deterioration in the color developing density, fixing sensitivity, etc. during long-term storage by forming the 2nd intermediate layer made of resin whose glass transition point is a specified temp. or above on the 1st intermediate layer made of water-soluble resin or emulsion between a basic substance generating layer and a color developing layer. CONSTITUTION:The 1st intermediate layer made of water-soluble resin such as polyvinyl alcohol or emulsion is formed on a basic substance generating layer contg. a Co (III) ammine complex, a specified polynuclear quinone oxidizing agent, a reducing agent capable of causing a photoinitiate redox reaction together with the oxidizing agent, and a chelating agent for Co (III). On the 1st layer the 2nd intermediate layer of polystyrene, polyester or the like with >=40 deg.C glass transition temp. and a color developing layer contg. leucotriarylmethane developing color by oxidation, acidic salt of strong acid and a photooxidizing agent are formed in succession to manufacture a photosensitiv and heat sensitive recording member. The 2nd intermediate layer prevents the polynuclear quinone or the chelating agent from diffusing in the color developing layer and subliming, and the shelf stability of the member is enhanced.
