Abstract (en)
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. The protective overcoat is applied from an aqueous coating.
