Abstract: Improving the adhesion of a gelatin coating to a styrene homopolymer or copolymer film by solvent treating and corona discharge treating the film prior to coating with a gelatin layer in the production of a coated photobase.

Abstract: Anti-static photographic films comprise a self-supporting synthetic plastics film base, such as a polyethylene terephthalate film, having superimposed on at least one side a gelatin-containing subbing layer and a radiation-sensitive layer superimposed on the gelatin layer, in which an anti-static material is included in the gelatin-containing subbing layer or being interposed as a layer between the gelatin-containing subbing layer and the radiation-sensitive layer, said anti-static material comprising a polymer or copolymer containing repeating units of the formula: ##STR1## wherein R represents hydrogen or methyl, R.sup.1 represents methyl or ethyl, R.sup.2 and R.sup.3 each independently represent methyl or ethyl or R.sup.2 and R.sup.3 taken together represent --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 -- or --(CH.sub.2).sub.n -- where n represents 4, 5 or 6, A represents an alkylene or substituted alkylene group and X.sup.
