摘要： A three-piece solid golf ball composed of a solid core, an intermediate layer which encloses the core, and a cover layer which encloses and is softer than the intermediate layer is characterized in that the solid core undergoes a deflection of 2.8 to 3.6 mm when a load of 130 kg is applied thereto from an initial load of 10 kg and has a surface hardness and a center hardness which differ by at least 15 Shore D hardness units; the intermediate layer has a surface hardness which differs from the surface hardness of the solid core by not more than 12 Shore D hardness units; and the cover layer has a surface hardness which differs from the surface hardness of the intermediate layer by at least 7 Shore D hardness units, is made primarily of a thermoplastic polyurethane, and has a thickness in a range of 0.5 to 1.3 mm. This combination of features provides an overall outstanding golf ball endowed with excellent flight characteristics, excellent controllability and durability, and a soft feel on impact.

摘要： The invention provides a solid golf ball having a solid core and a cover layer that encases the core and has an outermost layer on an outside surface of which are formed a plurality of dimples. The solid core is formed of a rubber composition composed of 100 parts by weight of a base rubber that includes 60 to 100 parts by weight of a polybutadiene rubber having a cis-1,4 bond content of at least 60% and synthesized using a rare-earth catalyst, 0.1 to 5 parts by weight of an organosulfur compound, an unsaturated carboxylic acid or a metal salt thereof, and an inorganic filler. The solid core has a deformation, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of 2.0 to 4.0 mm, and has a specific hardness distribution. The cover layer is formed by injection molding a single resin blend composed primarily of (A) a thermoplastic polyurethane and (B) a polyisocyanate compound, which resin blend contains a polyisocyanate compound in at least some portion of which all the isocyanate groups on the molecule remain in an unreacted state, and has a thickness of 0.5 to 2.5 mm, a Shore D hardness at the surface of 50 to 70. The golf ball has a deformation, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of 2.0 to 3.8 mm. The solid golf ball is advantageous overall in competitive use.
