Abstract

A golf ball having an indicia produced by ink jet printing is disclosed. An ink composition containing a coloring agent and a resin is dispensed on a transfer medium, using an ink jet printer, to form an indicia. The indicia is transferred from the transfer medium to the dimpled surface of a golf ball. In another form of the invention, an indicia is applied directly to a golf ball, without a transfer medium. In this method, an indicia receiving layer is applied on at least a portion of the golf ball surface, then the indicia is printed directly on the indicia receiving layer using an ink jet printer. The indicia on the golf ball has an impact resistance suitable for use in competitive play.

Claims

1. A golf ball having an indicia on its dimpled surface, the golf ball produced by the method comprising:

providing an ink composition adapted for ink jet printing the ink composition comprising aluminum trihydroxide in an amount ranging from 10 to 50 weight percent of the total weight of the ink composition and an aliphatic urethane triacrylate;

applying the ink composition in the form of the indicia on a transfer medium using an ink jet printer; and

transferring the indicia from the transfer medium to the dimpled surface of the golf ball, the indicia on the dimpled surface of the golf ball having a thickness of less than 100 microns.

2. The golf ball produced by the method according to claim 1, wherein the transfer medium comprises at least one member selected from the group consisting of silicone, fluoropolymer, polypropylene, and combinations thereof.

3. The golf ball produced by the method according to claim 1, wherein the transfer medium comprises a low surface energy material.

4. The golf ball produced by the method according to claim 1, wherein the transfer medium comprises silicone.

5. The golf ball produced by the method according to claim 1, wherein the transfer medium comprises a fluoropolymer.

6. The golf ball produced by the method according to claim 1, wherein the transfer medium comprises polypropylene.

7. The golf ball produced by the method according to claim 1, wherein the ink composition comprises a polymer resin.

8. The golf ball produced by the method according to claim 1, wherein the ink composition comprises resin components.

9. The golf ball produced by the method according to claim 1, further comprising:

forming a protective coating over the indicia on the dimpled surface of the golf ball.

10. The golf ball produced by the method according to claim 9, wherein the coating comprises a polyurethane.

11. The golf ball produced by the method according to claim 9, further comprising:

forming a primer coating layer on at least a portion of the dimpled surface of the golf ball prior to the applying step.

12. The golf ball produced by the method according to claim 11, wherein the primer coating layer includes a material which promotes at least one of absorption, adhesion and clarity of the indicia.

13. The golf ball produced by the method according to claim 12, wherein the material which promotes at least one of absorption, adhesion and clarity of the indicia includes at least one member selected from the group consisting of talc, amorphous silica, bentonite clay, and magnesium silicate.

14. The golf ball produced by the method according to claim 1, wherein the ink composition comprises a UV curable resin, further comprising:

curing the indicia after the indicia has been transferred onto the dimpled surface of the golf ball.

15. The golf ball produced by the method according to claim 1, wherein the transfer medium is a silicone-containing pad.

16. The golf ball produced by the method according to claim 1, wherein the transfer medium is a silicone-coated sheet.

17. The golf ball produced by the method according to claim 1, wherein the ink composition is an aqueous-based formulation.

18. The golf ball produced by the method according to claim 1, wherein the ink composition is a non-aqueous-based formulation.
