Abstract
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 processing-solution-permeable protective overcoat that is water resistant in the final processed product. The overcoat, before formation of the image, comprises hydrophobic polymeric particles in a gelatin matrix. Subsequent treatment of the overcoat, after formation of the image, to remove the gelatin, causes coalescence of the hydrophobic particles, resulting in the formation of a water-resistant continuous protective overcoat.
