PURPOSE:To enhance the preservability of a recording image and to prevent the generation of background fog under a high temp. and high humidity condition by adding a diphenylsulfone derivative and 2,2-di(4-glycidyloxyphenyl) propane to at least one of a recording layer and the intermediate layer provided between a support and the recording layer. CONSTITUTION:At least one kind of a diphenylsulfone derivative represented by formula [I] (wherein P4 is a hydrogen atom or an alkyl group, p and q are 0 or an integer of 1-5, r and s are integer of 1-5, R2 and R3 are respectively a halogen atom, an alkyl group or an alkoxy group, 1 is 0 or 1, m is 0 or an integer of 1-5 and n is 0 or an integer of 1-4) and 2,2-di(4-glycidyloxyphenyl) propane are contained in at least one of a recording layer and the intermediate layer provided between a support and the recording layer. As the diphenylsulfone derivative, for example, 4-(1,2-epoxyethyl)diphenyl sulfone or 4- glycidyldiphenylsulfone is designated. |
