A method of undercoating a polyester film of a light sensitive photographic material is disclosed in which one side of the film is pretreated such that the contact angle with water is below 58.degree.. Additionally, a layer of an aqueous dispersion containing no organic solvent is applied to said side of said film, said dispersion containing a copolymer containing up to 60% by weight of glycidyl methacrylate and 25-60% by weight of ethyl acrylate.

Method of undercoating treatment of polyester films for photographic

A hydrophobic plastic support which has a layer thereon comprising a copolymer, said copolymer consisting essentially of an acrylic monomer selected from alkyl esters of acrylic acid and alkyl esters of methacrylic acid, and an ethylenically unsaturated monomer having a group of the formula

Plastic support having improved adhesivness to material to be bonded

A light-sensitive silver halide photographic material having a cellulose ester film support coated on one side with a silver halide emulsion layer and on the other side with a non-light sensitive layer that is removable during an aqueous processing step. An optional portion of the non-light sensitive layer is coated with a magnetic recording layer formed from a dispersion containing at least 60% by weight of 2-ethoxyethanol. The resulting magnetic recording layer exhibits layer adhesion during subsequent development steps.

Light-sensitive silver halide photographic materials

The present application is directed to a process for subbing a photographic hydrophobic film which involves subjecting at least one surface of the film to a hydrophylizing pretreatment step, coating the pretreated surface with an aqueous dispersion containing a polymer which has particular comonomers in a combined amount of more than 76%, then coating the coated surface with a liquid containing colloidal silica.
