Patent number: 9815995Abstract: An ink for ink-jet printing used for ink-jet printing images onto the ink non-absorptive surfaces of cylindrical containers, and comprising at least a water-soluble solvent, a coloring material, a surfactant, a thickener and/or a binder resin, the coloring material being contained in an amount of 5 to 20% by weight, the surfactant in an amount of 0.1 to 5% by weight, the thickener in an amount of not more than 10% by weight, and the binder resin being contained in an amount of not more than 30% by weight. Owing to its ink-jet printability, the ink for ink-jet printing of the invention can be favorably used for printing images on the non-absorptive cylindrical containers such as seamless cans that are used for containing beverages and foods.Type: GrantFiled: January 31, 2013Date of Patent: November 14, 2017Assignees: TOYO SEIKAN GROUP HOLDINGS, LTD., TOKAN MATERIAL TECHNOLOGY CO., LTD.Inventors: Koji Yamada, Kenji Hayashi, Yukiko Saito, Hiroshi Shimomura
