Abstract
The invention relates to a photographic element comprising a paper base, at least one photosensitive silver halide layer, a layer of biaxially oriented polyolefin sheet between said paper base and said silver halide layer, wherein there is located between said biaxially oriented polyolefin sheet and said base paper a layer of adhesive resin comprising an ethylene polymer blended with at least one member selected from the group consisting of metallocene catalyzed polyolefin plastomer, ionomer, ethylene vinyl acetate copolymer, ethylene methyl methacrylate copolymer, ethylene ethyl acrylate copolymer, ethylene methyl acrylate copolymer, ethylene acrylic acid copolymer, ethylene ethyl acrylate maleic anhydride copolymer, or ethylene methacrylic acid copolymer.
