Abstract: A process for producing a photographic light-sensitive material comprising providing a first light-sensitive photographic emulsion layer on one side of a support having a surface resistivity greater than 10.sup.14 .OMEGA. and a thickness of not more than 230.mu. and providing a light-sensitive photographic emulsion layer or a gelatin-containing back layer on the opposite side of the support wherein between the time the first emulsion layer is coated and the time the opposite surface of the support is coated, (i) the opposite surface of the support is prevented from coming into contact with anything except rolls having a diameter larger than about 50 mm, and (ii) the water/gelatin weight ratio in the photographic emulsion layer(s) coated on the first surface of the support prior to coating the second surface is not less than 1. The process is particularly applicable to production of X-ray films.

Abstract: A method of subbing plastic films, particularly for use in photography, comprising applying an aqueous subbing composition to a surface thereof, the aqueous subbing composition comprising a polymer prepared from 45 to 99.5% by weight of at least one monomer selected from the group consisting of vinylidene chloride and vinyl chloride; 0.1 to 15% by weight of at least one monomer selected from vinyl monomers having one or more alcohol groups in their side chains; and 0 to 54.4% by weight of at least one monomer selected from the group consisting of acrylates, methacrylates, acrylonitrile, methacrylonitrile, alkyl vinyl esters, and alkyl vinyl ethers.
