摘要： The present invention provides an overcoat for a photographic element that allows for appropriate diffusion of photographic processing solutions. The overcoat comprises 10 to 50% by weight of a enzyme-degradable biopolymer and 50 to 90% by weight of hydrophobic particles (by weight of dry laydown of the entire overcoat). An enzyme is applied to the element before, during, or after conventional photoprocessing. According to one embodiment of the invention, the photographic element can be exposed and processed using normal photofinishing equipment, with no modifications, to provide an imaged element together with a protective, water-resistant layer.

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： A method of making a multi-layer micro-wire structure includes providing a substrate having a surface and forming a plurality of micro-channels in the surface. A first material composition is located in a first layer only in each micro-channel and not on the surface. A second material composition different from the first material composition is located in a second layer different from the first layer only in each micro-channel and not on the surface. The first material composition in the first layer and the second material composition in the second layer form an electrically conductive multi-layer micro-wire in each micro-channel.

摘要： The invention relates to continuous ink jet printing of an aqueous pigmented ink composition recycled from a main ink supply reservoir, employing a printer with a fluid delivery system capable of measuring the ink electrical resistivity, and providing needed quantities of either vehicle replenisher fluid or fresh ink to maintain the desired recycled ink concentration. The electrical resistivity of the pigmented ink can be modified advantageously for stable ink recycling by the addition of the organic amine salt of an acid, and the pH stability of the ink can be simultaneously improved by the additional inclusion of the neutral form of the organic amine in similar molar proportions to the amine salt. The pigmented ink jet ink compositions provide for particularly stable and invariant fluid properties during periods of extended printer operation and ink recirculation.
