Patent number: 8486515Abstract: Disclosed is a coating composition for a plastic label, which contains an oxetane compound, an epoxy compound, and a cyclic acetal and/or a poly(vinyl butyral). The coating composition excels in suitability for printing such as gravure printing or flexographic printing, cures rapidly to give excellent productivity, and after curing, gives a coating layer that excels in adhesion to a plastic base film and in toughness. A plastic label formed using the coating composition excels in surface scratch resistance and crumpling resistance, and therefore is particularly useful as a label for use in plastic containers, and metal containers such as bottle cans.Type: GrantFiled: December 19, 2006Date of Patent: July 16, 2013Assignee: Fuji Seal International, Inc.Inventors: Kazuyuki Ishida, Akira Shintani, Akira Miyazaki, Suguru Arai
