Golf ball paint composition and golf ball

Abstract

A paint composition comprising an aqueous resin having photo-curable functional groups in a molecule, a photoinitiator, and a crosslinker is suitable for use on golf balls since the composition is fully adherent to molded parts of ionomer resins and urethane resins commonly used in golf ball covers, eliminates a need for pre-treatment of the ball surface, and forms a cured coating having a high bond strength to the ball surface. The composition which is photo-curable ensures efficient operation in the golf ball manufacturing process. In a golf ball coated with the paint composition, the coating has abrasion durability.

1 . A paint composition for golf balls, comprising an aqueous resin having photo-curable functional groups in a molecule, a photoinitiator, and a crosslinker.  
     
     
         2 . The paint composition of  claim 1  wherein the crosslinker is a carbodiimide or ethyleneimine base crosslinker.  
     
     
         3 . A golf ball having a coating of the paint composition of  claim 1  on an exterior surface thereof.
