摘要： In a solid golf ball comprising an elastic solid core and a resin cover, the cover has a JIS-C hardness of 50-85, and provided that the ball receives a spin rate S1 (rpm) in the dry state and a spin rate S2 (rpm) in the wet state when hit with a short iron having a loft of an 8-iron or greater, the percent spin retention: (S2/S1)×100 is at least 47%. The ball's spin susceptibility when hit with the short iron is not reduced in the dry state or fine weather, nor is noticeably reduced even in the wet state or rain weather. The ball has so high performance that the ball travels a distance as intended, immediately stops on the green, is easy to control and thus, suited for professional and amateur low-handicap golfers.

摘要： In a multi-piece solid golf ball comprising a rubbery elastic solid core and a resin cover including at least an inner layer, an intermediate layer and an outer layer, the solid core undergoes a deflection of 1.6-6.0 mm under an applied load of 294 N (30 kgf), the cover inner layer has a Shore D hardness of 55-70, the cover intermediate layer has a Shore D hardness of 8-50 and a gage of 0.1-1.2 mm, and the cover outer layer has a Shore D hardness of 40-55. The ball prevents any undesired increase of spin upon driver shots without detracting from rebound, has good flight performance, and receives enough spin to facilitate control on short iron shots.
