Abstract
Abstract A method of producing a urethane painted solid polyurethane golf ball and the resulting structure. The steps in painting a solid polyurethane golf ball include soaking the golf ball in an acetone bath for approximately 20 minutes with intermittent agitation, applying a first coat of pigmented urethane paint to the golf ball approximately 5 hours after removing the golf ball from the acetone bath, applying a second coat of pigmented urethane paint to the golf ball approximately 10 hours after the first coat of paint has been applied thereto, stamping the golf ball 10 hours after the second coat of paint has been applied thereto, and clear coating the golf ball with a coat of clear urethane paint after it has been stamped. In the resulting painted golf ball structure, the paint adheres strongly to the golf ball due to the initial acetone treatment of the golf ball.
