Abstract
A golf ball includes one or more coating layer on a golf ball surface having a plurality of dimples thereon. At least one coating layer is formed of a two-component curable urethane coating composition having a polyol component and a polyisocyanate component, which polyol component is an acrylic polyol or a polyester polyol. The coating composition contains less than 5 wt % of polyurethane particles, relative to base resin solids within the composition. The coating layer formed on the ball surface suppresses coating sag, improves the film thickness edge ratio between the film thickness at the middle portion and the film thickness at edge portions of the dimples, and has an improved scuff resistance, peel resistance and marking protective effect.
