Peel apart photosensitive material utilizing a barrier layer containing an aromatic (meth)acrylate containing copolymer with a T.sub.g under 70.degree. C.

Abstract

A photosensitive material either comprises a support, a peel layer, a barrier layer and a coloring material-containing photosensitive layer or a laminate of a coloring material layer and a photosensitive layer, superposed in order, or comprises a support having a releasing surface, an intermediate layer instead of both the peel layer and the barrier layer as mentioned above, a coloring material-containing photosensitive layer or a laminate of a coloring material layer and a photosensitive layer, superposed in order. The barrier layer or the intermediate layer comprises a polymer having a glass transition temperature not higher than 70.degree. C. which is selected from the group consisting of a homopolymer of an acrylate monomer having an aromatic ring, a methacrylate monomer having an aromatic ring, an acrylamide monomer having an aromatic ring or a methacrylamide monomer having an aromatic ring, a copolymer of two or more of these monomers, and a copolymer of 50 molar % or more of one or more of these monomers and 50 molar % or less of one or two of other copolymerizable monomers.
