发明名称 GOLF BALL
摘要 A golf ball has a plurality of dimples, wherein: (1) the dimples have a peripheral edge with a radius of curvature R from 0.5 mm to 2.5 mm; (2) the surface coverage SR of the dimples, expressed as a percentage of the surface area of a hypothetical sphere representing the ball if it had no dimples, is from 60% to 74%; and (3) the ratio ER of a collective number of dimples RA having a radius of curvature R to diameter D ratio (R/D) of at least 20%, divided by a total number of dimples N on the surface of the ball, is from 15% to 95%. This combination of features enables damage to the paint film on the surface of the ball to be minimized, improves the durability of markings on the surface of the ball, and prevents a decline in ball performance.
