Plural coated sheet material
专利汇可以提供Plural coated sheet material专利检索，专利查询，专利分析的服务。并且Improved adherence is obtained for sheet material having a hydrophobic film support or base, such as a hydrophobic cellulose ester or polyester, by the combination of a vinyl polymer subbing layer arranged directly on the hydrophobic support, the subbing layer being formed of a copolymer containing at least 45 percent by weight of vinylidene chloride and/or vinyl chloride monomer along with a minor amount of a hydrophilic vinyl monomer with the balance being constituted by any other vinyl monomer, and superimposed upon the vinyl subbing layer a layer containing a mixture of gelatin with a copolymer of butadiene and a vinyl monomer containing 30-70 percent by weight of butadiene, the ratio of the gelatin to the butadiene copolymer being in the range of 1:3 to 2:1 by weight. An additional layer can be applied over the gelatin/copolymer layer and constituted by such ingredients as are desirable for the particular utility of the resultant sheet material, such as light-sensitive silver halide emulsion photographic layers, electrophotographic layers containing finely divided photoconductive material such as zinc oxide or some other photosensitive semiconductive material, matte layers containing pigment, diffusion transfer layers containing development nuclei and so on. Alternatively, the ingredients appropriate to some particular ultimate utility can be incorporated into the gelatin/butadiene copolymer layer directly.，下面是Plural coated sheet material专利的具体信息内容。
