ABSTRACT:
The present invention is a photographic element which includes a support having a front surface and a back surface, and a silver halide imaging layer superposed on the front side of the support. A backing layer is superposed on the backside of the support and is formed by the coating and subsequent drying of an aqueous coating composition having therein a mixture of film-forming colloidal particles and non-film-forming colloidal particles and a fluoropolyether comprising more than 90 mole % units selected from the group consisting of --CF.sub.2 --CF.sub.2 --O--, --CF.sub.2 --O--, --CF(CF.sub.3)--O--, and --CF.sub.2 --CF(CF.sub.3)--O--, and a functional group selected from the group consisting of COOH, --CH.sub.2 --OH, --CH.sub.2 --COOH, --CH.sub.2 --SO.sub.3 H, --CH.sub.2 --PO.sub.3 H, --(CH.sub.2 --CH.sub.2 --O)--H, and --(CH.sub.2 --CH(CH.sub.3)--O--)--H.
