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 |
20110281103 | BLOCK COPOLYMERS AND BLOCK COPOLYMER NANOPARTICLE COMPOSITIONS - Copolymers and methods using the copolymers control the stability, the homogeneity of mixtures and the chargeability of a nanoparticle. A block copolymer-nanoparticle composition includes first, second and third block units that each include repeating units of respective monomers. The monomer of the first block unit includes a binding group that binds to the nanoparticle. The monomer of the second block unit includes a hydrophobic moiety that provides steric stabilization of the nanoparticle and homogeneity of mixtures of the copolymer-nanoparticle composition in a non-polar medium. The monomer of the third block unit includes a chargeable group that imparts a charge to the nanoparticle. An order of the respective block units in the copolymer and the number of repeating units of the monomer in the respective block units control the stability, the homogeneity of mixtures and the charge of the nanoparticle. | 11-17-2011 |
