Abstract: The present invention provides water-based energy curable compositions that exhibit improved printability, adhesion, opacity, and wash-up properties. The compositions comprise one or more inert water-based polyurethane resins and one or more water-based phosphate esters. Addition of the inert polyurethane resins and phosphate esters improves adhesion of the energy curable compositions to a variety of substrates.

Abstract: Provided are overprint varnish (OPV) compositions containing high viscosity essentially non-aqueous dispersions that include acrylic core/shell polymer particles in a non-aqueous solvent such as mineral oil. Also provided are methods of coating a substrate with an OPV containing the non-aqueous dispersions to improve the properties of the OPV when used to coat a substrate, such as improved rub resistance, resistance to yellowing, and desirable gloss values.

Abstract: Lithographic printing inks are described, which are characterized by the inclusion of both water, in a substantially emulsified form, and inorganic filler. Inks of the present invention show improved printing properties in offset lithography, including improved transfer, reduced piling and improved mileage. They also offer cost advantages over currently available inks and the ability to minimize or eliminate entirely mineral oil from their compositions. The inks of the present invention may be used in both web-based print processes including coldset and heatset, as well as in sheetfed printing. The inks may be dried to a durable ink film at ambient temperature, with thermal energy or with actinic or electron beam radiation, or with any combination thereof.

Abstract: Described herein are water-based inks that comprise water, a water miscible solvent having a boiling point of about 56° C. to about 98° C., and a latex. In one aspect, the water miscible solvent comprises about 10 wt % to about 30 wt % of the ink (based on the total weight of the ink). In another aspect, the latex is an alcohol-tolerant latex that exhibits limited or no particle size increase in the presence of alcohol. Further described herein are articles printed with the inks, and methods of printing with the inks.

Abstract: The present invention provides alkoxylated polymers. The alkoxylated polymers have two or more alkoxylated sites. The alkoxylated polymers can comprise any monomers and/or oligomers that contain one or more functional groups with an active hydrogen. The alkoxylated polymers are useful in any application for which polymers are generally used. For example, the alkoxylated polymers are useful as additives in ink and coating compositions.

Abstract: The present invention is directed to energy curable offset conductive inks and hybrid offset conductive ink compositions that contain an oxidative curable ink and the energy curable offset conductive ink. The conductive inks and ink compositions exhibit low levels of resistance and hence have superior conductivity.

Abstract: Provided are high viscosity essentially non-aqueous dispersions containing acrylic core/shell polymer particles in a non-aqueous solvent; sheetfed, heatset and coldset lithographic ink compositions containing the dispersions; and methods of printing with ink containing the dispersions to improve the setting and drying properties and rub resistance of sheet fed offset, heatset and coldset lithographic inks. The lithographic inks containing the dispersions set quickly enough to allow processing of printed sheets soon after printing.
