Abstract:
An ultraviolet radiation curable water-insoluble production ink for forming an inked surface on at least a portion of a surface of a ball, at least said inked surface thereafter being coated with a topcoat, said ink comprising:(a) a prepolymer having at least two prepolymer functional moieties, said prepolymer being selected from the group consisting of a first acrylated prepolymer, an unsaturated ester, and mixtures thereof,(b) a monomer polymerizable with the prepolymer;(c) a photoinitiator; and(d) an adhesion promoting component, wherein said adhesion promoting component is selected from the group consisting of a carboxylic acid functional monomer, a carboxylic acid functional oligomer, and mixtures thereof, wherein said adhesion promoting functional moiety comprises at least about 2 moles of a carbonyl functionality per mole of said adhesion promoting component, and wherein said component being sufficient to maintain adhesion of at least about 75% of said inked surface to said topcoat and to said ball surface upon ultraviolet radiation curing said ink and after coating said ink with said topcoat.
