US Classification:

430 14, 430350, 430533, 430432, 430961

Abstract:

The present invention relates to imaged photographic elements comprising an overcoat layer of a water-dispersible, hydrophobic polyester resin having the following general formula: wherein I is an ionic group; n is an integer from 1-3; P is a polyester backbone; A is an Asiatic group comprising a straight or branched chain fatty acid or triglyceride thereof having from about 6 to about 24 carbon atoms; and m is an integer from 3-8. Such a protective overcoat provides excellent stain resistance for an imaged photographic element.
