Abstract:
A method for reducing the tendency toward formation of coating non-uniformities in the coating of a multilayer photographic element comprising the steps of:(a) preparing coating compositions for a non-gelatin-containing layer and gelatin-containing layer, which layers comprise a layered mass suitable for coating on a moving web, which layered mass further comprises at least one silver-halide emulsion layer, wherein the osmotic pressure of the coating composition for the non-gelatin-containing layer is not more than 30 percent less than the osmotic pressure of the coating composition for the gelatin-containing layer, as measured at the temperature of coating; (b) forming a laminar flow of the layered mass which includes said coating compositions as distinct layers, said non-gelatin-containing layer overlying and adjacent to said gelatin-containing layer, wherein said gelatin-containing layer is the topmost gelatin-containing layer in the layered mass; and (c) receiving said layered mass as a layered coating on a moving web comprising a photographic support, at a coating application point, wherein the layered mass, including the non-gelatin-containing layer and gelatin-containing layer, is simultaneously applied to the moving web with said silver-halide emulsion layer.
