| description | PURPOSE:To enhance recording sensitivity and to reduce the lowering in sensitivity and optical density, by providing a protective layer containing polyvinyl butyral, an epoxy resin and nitrocellulose on a protective layer based on an ethylene/vinyl acetate copolymer. CONSTITUTION:A first protective layer containing an ethylene-vinyl acetate copolymer is provided on a recording layer and a protective layer containing a mixture of polyvinyl butyral, an epoxy resin and nitrocellulose is provided on said first protective layer. By this method, the lowering in sensitivity is reduced and mechanical strength is enhanced and the deterioration in the recording layer or crack generation of the protective layer is eliminated because stress between the ethylene/vinyl acetate copolymer layer and the layer containing polyvinyl butyral, the epoxy resin and nitrocellulose is relieved and the layer containing polyvinyl butyral and the epoxy resin is low in air permeability and, when a recording material is bent, cracks are not generated in the protective layers. |
