ABSTRACT:
Mixtures of an alkyl vinyl ether/maleic anhydride copolymer or an alkylethylene/maleic anhydride copolymer with cellulose acetate provide protective overcoats for thermally developable materials. These protective overcoats exhibit good adhesion to the emulsion layer, are physically hard, and have good optical clarity while maintaining the sensitometric properties of the materials.
