    摘要： In a multi-piece solid golf ball comprising a solid core and a cover with a multilayer construction including an innermost layer, an intermediate layer, and an outermost layer having a plurality of dimples on the surface thereof, the innermost and outermost layers each have a Shore D hardness of at least 60, and the intermediate layer has a Shore D hardness of at most 40. The total number of dimples is 370-450, and the dimples cover at least 65% of the golf ball surface. The ball gives a good, soft feel when hit with any type of club. The performance of the ball little depends on the head speed.

    摘要： A wound golf ball is constructed by winding thread rubber on a center ball and enclosing with a cover. The center ball consists of a center core having a diameter of 27-37 mm and experiencing a distortion of 3.5-10 mm under a load of 100 kg and an enclosure layer having a Shore D hardness of 55-68 and has a diameter of 33-38 mm. The cover consists of an inner layer having a Shore D hardness of 55-68 and an outer layer having a Shore D hardness of 30-58, the inner layer being harder than the outer layer by at least 5 in Shore D hardness. The ball is improved in spin, control and flight distance at any head speed from high to low ranges so that players may favorably use it independent of their skill or head speed.

    摘要： A multi-piece golf ball includes a core 30–40 mm in diameter, an intermediate layer including an outermost layer 0.5–2.0 mm thick, and a cover 0.5–2.0 mm thick. The core is a rubber composition mainly containing polybutadiene. The outermost layer is a resin material containing an ionomer resin in an amount of 30% by weight or more. The cover material is obtained by dispersedly blending a silicone powder in a main resin containing an ionomer resin in an amount of 50% by weight or more. The hardness of the outermost layer is harder than the hardness of the core's a center portion. The hardness of the cover is harder than the hardness of the outermost layer. A difference in hardness between the cover and the center portion of the core satisfies a relation of 10≦(Durometer D hardness of cover−Durometer D hardness of center portion of core≦40.

    摘要： A multi-piece golf ball includes a core having a diameter of 30 to 40 mm, at least one intermediate layer including the outermost layer having a thickness of 0.5 to 2.0 mm, and a cover having a thickness of 0.5 to 2.0 mm. The core is made from a rubber composition mainly containing polybutadiene. The outermost layer is made from a resin material containing an ionomer resin in an amount of 30% by weight or more. The cover is made from a material obtained by dispersedly blending at least one kind of silicone powder selected from a silicone rubber powder, a silicon resin powder, and a composite powder thereof, in a main resin component containing an ionomer resin in an amount of 50% by weight or more. The hardness of said cover is smaller than the hardness of said outermost layer of said at least one intermediate layer and is larger than the hardness of a center portion of said core. The multi-piece golf ball is excellent in resilience, durability, feel of hitting, and controllability.
