| 20110012955 | INK-JET OVERCOAT COMPOSITION AND RELATED SYSTEMS AND METHODS - Compositions, systems, and methods for improving dry rub resistance and resistance to highlighter smear of a printed image on a substrate are provided. The overcoating composition can comprise an aqueous-based liquid vehicle and about 0.5 wt % to about 40 wt % latex polymer particles dispersed in the liquid vehicle. The latex polymer particles can include about 18 wt % to about 99.5 wt % polymerized hydrophobic monomers selected from the group of 4-methylstyrene, cyclohexyl acrylate, isobornyl methacrylate, isobornyl acrylate, and combinations thereof, about 0.1 wt % to about 20 wt % polymerized acid monomers. The overcoating composition can be formulated to be ink-jetted onto the substrate and is substantially devoid of colorant. | 01-20-2011 |
| 20110073134 | PROCESS FOR REMOVING INK FROM PRINTED SUBSTRATE - A process for removing ink from a printed media substrate. Such process includes the step of providing a media substrate including an ink printed image wherein the ink composition or the media substrate contains photolabile entities. Then the process includes the step of applying UV light on the printed substrate wherein the emitted UV light has a wavelength value which is below the threshold wavelength of the photolabile entities. | 03-31-2011 |
| 20110094413 | PHTHALOCYANINE DYE AND INK CONTAINING THE SAME - Phthalocyanine dyes represented by the general structures (I) to (IV) and inkjet ink formulation including the phthalocyanine dyes. | 04-28-2011 |

| 20110172358 | FUNCTIONALIZED LATEX POLYMER AND METHOD OF FORMING THE SAME - A method for forming a functionalized latex polymer includes polymerizing a heterogeneous dispersion of water insoluble monomers in water, thereby forming a latex polymer. An at least partially water soluble halogenated non-ionic group is reacted with the latex polymer, whereby a halogen is displaced from the non-ionic group, thereby forming an at least partially water soluble non-ionic group that attaches to the latex polymer. | 07-14-2011 |
