Abstract
A multi-piece golf ball is manufactured by molding a cover layer and a core layer to form a golf ball preform in a mold. The cover layer has a thermoplastic polyurethane composition which may be crosslinked by ultraviolet radiation. After molding, the golf ball preform is removed from the mold. A UV curable topcoat composition is applied to the golf ball preform. The golf ball preform is then irradiated with ultraviolet radiation under conditions sufficient to both crosslink the crosslinkable thermoplastic polyurethane and cure the UV curable topcoat composition.
