US Classification:

430311, 430 7

Abstract:

The invention relates to a process for forming a structure comprising: (a) providing a transparent support; (b) forming a color mask having a selected absorption spectral range wherein the color mask has an effectively transparent portion and a partially absorptive portion, wherein the partially absorptive portion includes at least two portions having different optical densities within the absorption spectral range; (c) coating a layer of a photopatternable material sensitive to visible light in the absorption spectral range; (d) exposing and developing the photopatternable material to form a photopattern corresponding to at least one of said two portions of the partially absorptive portion; and (e) depositing and patterning a layer of functional material such that a pattern of functional material results corresponding to the at least one of said two portions of the partially absorptive portion.

G03G 800
G03G 1322

US Classification:

430124

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 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.
