Ultraviolet and or/ visible light curable inks with photoinitiators for game balls, golf balls and the like

A 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 acrylate, an ester and mixtures thereof;
• (b) a polymerizable monomer;
• (c) a visible light photoinitiator having an absorbance spectrum in both the ultraviolet and visible light regions and wherein a substantial portion of the absorbance spectrum is at wavelengths greater then about 400 nm;
• (d) a co-initiator;
• (e) an adhesion promoting component having at least one adhesion promoting functional moiety, 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 curing of said ink and after coating said ink with said topcoat;
• and
• (f) an ultraviolet light photoinitiator.

A radiation curable water-insoluble logo ink for forming an inked surface on at least a portion of a topcoated surface of a ball, said ink comprising:

• (a) a prepolymer having at least two prepolymer functional moieties, said prepolymer being selected from the group consisting of a first acrylate, an ester and mixtures thereof;
• (b) a polymerizable monomer;
• (c) a visible light photoinitiator;
• and
• (d) a toughening agent, said toughening agent being sufficient to cause adhesion of said ink to said topcoat of at least about 75% of said inked surface after curing.
