Publication number: 20090163614Abstract: The invention provides a coating composition comprising a thermal plastic resin selected from the group consisting of a polycycloolefin resin, polyester resin, polyacrylate resin, and a mixture thereof; and a radiation curable resin comprising a radiation polymer containing at least one mono- or multi-functional acrylic acid based monomer as a polymerization unit, an oligomer containing an ethylenically unsaturated functional group, and a photoinitiator, wherein the radiation curable resin is used in an amount of 220-1000% by weight on the basis of the weight of the thermal plastic resin. The invention improves the hardness of the coating composition, prevent the coated substrate from being scratched or impaired, and impart the substrate with high transparency without causing warping problem.Type: ApplicationFiled: December 19, 2008Publication date: June 25, 2009Inventors: Lung-Lin HSU, Sue-Hong LIU

Patent number: 7538145Abstract: The phase change, curable composition comprises curable monomer, photoinitiator that initiates polymerization of the curable monomer, and phase change agent that provides the composition with an increase in viscosity of at least four orders of magnitude, from a first temperature, the first temperature being from 50° C. to 130° C., to a second temperature, the second temperature being from 0° C. to 70° C., wherein the second temperature is at least 10° C. below the first temperature. A coating over an image may be applied by providing a composition comprising curable monomer at a first temperature; applying the composition over the image, the image being at a second temperature; and exposing the composition to radiation to initiate polymerization of the curable monomer. In this process, the composition has a viscosity at the second temperature that is at least four orders of magnitude greater than its viscosity at the first temperature.Type: GrantFiled: November 30, 2005Date of Patent: May 26, 2009Assignee: Xerox CorporationInventors: Jennifer L. Belelie, Peter G. Odell, Darly Vanbesien, Marcel P. Breton
