Conventional adhesive substratum compositions (eg subbing compositions of, for example, aqueous emulsions of a polymerized vinylidene chloride/methyl acrylate/itaconic acid terpolymer) can be used for coating dimensionally stable, hydrophobic macromolecular film bases (eg polyethylene terephthalate) after said base has been biaxially stretched by treating said subbing composition with an ion exchange resin

Photographic subbing composition having improved anchorage

A light-sensitive material comprising a polyester film, the surface of the polyester film being subjected to a treatment to render the surface hydrophilic, a subbing layer on the treated surface comprising a polymer having carboxyl groups or groups which form carboxyl groups upon hydrolysis and an addition polymerizable monomer selected from the group consisting of acrylic acid, itaconic acid, hexahydro-1,3,5-triacryl-s-triazine, N,N'-bisacryloyl piperazine, diacetone acrylamide and hexamethylene bis-ethyleneureide and a silver halide emulsion layer on the subbing layer, whereby good adhesion between the polyester film and the coating layer is obtained.
