The present invention is an imaging base which includes a polyester film support and an adhesion promoting layer directly adhered to a surface of the support. The adhesion promoting layer is formed by the coating and subsequent drying of a coating composition comprising a gelatin-grafted-polyurethane. The gelatin-grafted polyurethane is covalently bound to the polyurethane through a grafting agent wherein the ratio of gelatin to polyurethane is from 1:10 to 2:1. In one embodiment of the invention the imaging support is coated with at least one silver halide emulsion layer to form a photographic element.

Improved aluminum substrates suitable for use in the production of lithographic printing plates. A surfactant surface treatment for such aluminum substrates improves the quality of radiation sensitive coatings subsequently applied to the substrate. The surfactant may be in a layer comprising a mixture of a hydrophilizing composition and a surfactant on the aluminum alloy surface; or a hydrophilizing layer comprising a hydrophilizing composition may be on the aluminum alloy surface and a surfactant layer comprising a surfactant on the hydrophilizing layer.
