PURPOSE:To enhance the sensitivity and contrast of a recording member by forming the 1st layer consisting of ZnO and a binder and the 2nd layer consisting of a Co (III) complex, a photoreducing agent, a hydrogen donor and a binder on a support in order. CONSTITUTION:The 1st layer consisting of electrophotographic high purity ZnO 1pts.wt. and a binder such as gelatin, celluloses or a vinyl polymer 0.1-30 parts is formed on a support such as paper or plastics by coating and drying, and the 2nd layer consisting of a Co (III) comples such as CO(NH2)6 or CF3COO3, a photoreducing agent such as p-benzoquinone, a hydrogen donor such as polyethylene glycol and the above-mentioned binder is formed to manufacture a recording member which is color developed by heating after visible light irradiation. Thus, by forming the ZnO-contg. layer, the sensitivity of the resulting recording member is enhanced, and the shelf stability of the photosensitive material is enhanced by separating the ZnO-contg. layer and the Co complex-contg. layer. |
