ABSTRACT:
An easily regeneratable printed thermoplastic resin product is provided by printing it with a specific radiation-curable ink composition and curing the printed ink with radiation to form a cured ink film thereon. The ink composition comprises a vehicle mixture containing: (A) at least one linear polyester oligomer and/or polymer substantially free of an acid group and a polymerizable double bond on the linear polyester chain wherein 1 to 10 double bonds are pendent from the linear polyester chain, and/or mixture thereof, (B) at least one single double bond-containing carboxylic acid and/or ester and/or amide wherein the acid has at least one acid group, and/or mixture thereof, (C) a double bond-containing polycarboxylic ester wherein 2 to 10 acid groups are present and at least 2 double bonds are pendent from the carboxylic ester having 2 to 10 acid groups, (D) at least one double bond-containing fluorinated carboxylic ester, and/or block copolymer comprising a fluorinated alkyl group-containing polymer segment and a (meth)acrylic polymer segment, and/or block copolymer comprising a siloxane group-containing polymer segment and a (meth)acrylic polymer segment, and/or mixture thereof, (E) a double bond-containing carboxylic ester, having at least 2 double bonds and free of an acid group, provided that it is excluded from the above-mentioned ingredient (A), and (F) at least one single double bond-containing carboxylic ester and/or amide and/or imide free of an acid group, and/or mixture thereof, wherein the acid value of the vehicle mixture is from 5 to 100. The ink is useful in displaying and decorating trade names, designs, explanatory notes, bar code, etc. on specific thermoplastic products and the cured ink film is easily detachable with an aqueous alkali solution.
