Abstract
The present invention provides a coating material for a golf ball. The coating material comprises a polyol(1) containing a urethane polyol and a polyisocyanate. The urethane polyol is produced by the reaction between a diisocyanate and a polyol(2) containing as an essential ingredient a diol and a triol at the triol/diol equivalent ratio of 0.2 to 3. The urethane polyol has Mw of 4000 to less than 10000. The coating material is dryable in a short time at low temperatures and forms a coating layer having excellent resistance to scuffing and adhesion to a golf ball main body.
