Ink for ink-jet printing, printed cylindrical containers and method for producing the same
First Claim
1. A method of producing a printed cylindrical container by effecting an ink-jet printing on an ink non-absorptive surface of the cylindrical container by using an ink for ink-jet printing, and applying a finishing varnish on the ink non-absorptive surface, whereinthe ink for ink-jet printing comprises at least a water-soluble solvent, a coloring material selected from the group consisting of an inorganic pigment, an organic pigment and a dye, a surfactant, a thickener and/or a binder resin, the coloring material is contained in an amount of 5 to 20% by weight, the surfactant is contained in an amount of 0.1 to 5% by weight, the thickener is contained in an amount of not more than 10% by weight, and the binder resin is contained in an amount of not more than 30% by weight.

Abstract
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.
