Abstract
A urethane top coat prepared by combining a polyol and a blend of an aliphatic diisocyanate and an aliphatic/aromatic polyisocyanate copolymer is provided, along with a method for its use as the top coating for a golf ball. The inventive top coating demonstrates an increased rate of curing compared to other top coatings having similar abrasion resistance and color retention qualities.
