    摘要： A multi-piece solid golf ball comprises a solid core and a cover of at least two layers enclosing the core and having a number of dimples in cover outer layer surface. The solid core is formed of a rubber base and has a specific gravity of at least 1.00. The cover is formed of a thermoplastic resin and the cover outer layer has a greater specific gravity than the core or a cover inner layer. The golf ball has an inertia moment (M) within the range given by the following expression: M.sub.DL .ltoreq.M.ltoreq.M.sub.UL wherein M.sub.UL =0.08D+84.8 and M.sub.DL =0.08D+77.8 wherein D is a Shore D hardness of the cover, the dimples occupy at least 60% of the ball surface, and V.sub.0 is in the range of 0.4 to 0.65. The ball is improved in flight distance, controllability, roll and straight travel upon putting.

    摘要： A two-piece solid golf ball comprises a solid core and a cover enclosing the core and having a number of dimples in its surface. The solid core is formed of a rubber base and has a specific gravity of at least 1.00. The cover has a greater specific gravity than the core. The golf ball has an inertia moment (M) within the range given by the following expression: M.sub.DL .ltoreq.M.ltoreq.M.sub.UL wherein M.sub.UL =0.08D+84.8 and M.sub.DL =0.08D+77.8 wherein D is a Shore D hardness of the cover, the dimples occupy at least 60% of the ball surface, and V.sub.0 is in the range of 0.4 to 0.65. V.sub.0 is the ratio of the volume of the dimple space below a plane circumscribed by the dimple edge to the volume of a cylinder whose bottom is the plane and whose height is the maximum depth of the dimple measured from the bottom. The ball is improved in flight distance, controllability, roll and straight travel upon putting.

    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.
