    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.

    摘要: An inkjet printing system includes an inkjet printer responsive to digital signals and containing an ink composition having: (a) water, (b) dispersed pigment particles, (c) a humectant, and (d) a polyurethane additive having at least a first soft segment having siloxane groups, the additive having a weight average molecular weight of at least 10,000 daltons and a sufficient number of acid groups to provide an acid number greater than 60. An improved combination of scratch resistance and jetability is obtained.
