发明名称 Protecting layer for gelatin based AGX photographic products
摘要 The present invention is an imaged photographic element which includes a support, at least one silver halide light-sensitive emulsion layer superposed on the support; and a protective overcoat furthest from the support. The protective overcoat is superposed on the silver halide light sensitive layer. The protective overcoat includes a first polymeric particle having a glass transition temperature of greater than or equal to 25 DEG C. and a particle size of from 5 to 500 nm and a second polymeric particle having a glass transition temperature of less than 25 DEG C. and a particle size of from 5 to 500 nm at a weight ratio of the first polymeric particle to the second polymeric particle of from 3:97 to 80:20 and wax particle having a size of from 0.01 mu m to 0.5 mu m. The protective overcoat is applied from an aqueous coating.
