Patent number: 7214725Abstract: The present invention relates generally to radiation-curable ink formulations, and particularly, but not by way of limitation, to a family of radiation-curable ink formulations specifically for lithographic printing applications. The inventive ink formulations are based on multifunctional acrylate resins formed by the reaction of acrylate monomers and oligomers with ?-keto esters (e.g., acetoacetates), ?-diketones (e.g., 2,4-pentanedione), ?-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other ?-dicarbonyl compounds that can participate in Michael addition reactions.Type: GrantFiled: April 30, 2004Date of Patent: May 8, 2007Assignee: Ashland Licensing and Intellectual Property LLCInventors: Sridevi Narayan-Sarathy, Lisa M. Hahn

Patent number: 7192992Abstract: Disclosed are environmentally friendly, substantially all solids coating compositions which are curable using ultraviolet and visible radiation. In addition, the disclosed coating compositions are suitable for coating thermally sensitive objects and/or rusted surfaces. In addition, methods are disclosed for coating surfaces, or at least a portion of the surfaces, and curing of the coated surface to obtain partially or fully cured coated surfaces are also disclosed. Furthermore, articles of manufacture incorporating fully cured coated surfaces are disclosed, including, for example gas tanks such as, barbeque propane tanks. Also disclosed are methods, processes, production lines, articles of manufacture, and factories which incorporate these environmentally friendly, substantially all solids coating compositions curable using ultraviolet and visible radiation.Type: GrantFiled: December 2, 2004Date of Patent: March 20, 2007Assignee: Ecology Coating, Inc.Inventor: Sally W. Ramsey
