ABSTRACT:
An electrographic image transfer element having a protective coating is disclosed. The protective coating is a single protective layer that contains a fluoropolymer and an acrylic polymer. Because the protective coating is resistant to surface pitting, dirt, stains, and general degradation, images formed from the element can be used effectively on billboards, banners, and other outdoor signs.
