发明名称 Water-resistant polyurethane overcoat for imaging materials
摘要 The present invention relates to imaging elements, including photographic elements and recording media, having a protective overcoat that resists fingerprints, common stains, and spills. More particularly, the present invention provides a water permeable overcoat during image formation but that is water resistant in the final processed product. The overcoat, before formation of the image, comprises polyurethane particles in a gelatin-containing matrix. Subsequent to formation of the image, the overcoat is heat fused, resulting in the formation of a water-resistant continuous protective overcoat that provides excellent scratch and spill resistance.
