    摘要： A golf ball includes a solid core, an intermediate layer, and a cover having dimples formed therein. The core has a Shore D hardness at the surface of 30-48, the intermediate layer has a Shore D hardness of 53-60, and the cover has a higher Shore D hardness of 55-65. In the cover, 370 to 450 dimples of at least two types having different diameters and/or depths are distributed so as to cover at least 63% of the ball surface. The index Dst of the overall dimple surface area is at least 4. The golf ball provides significantly improved flight distance and a good feel by virtue of a good balance in hardness and optimized dimple characteristics.

    摘要： In a solid golf ball having a solid core, a cover inner layer and a cover outer layer, the inner layer is formed of a thermoplastic resin containing 60-100% by weight of an ionomer resin neutralized with a monovalent metal salt, and the outer layer is formed of a thermoplastic resin containing 60-100% by weight of an ionomer resin neutralized with a divalent metal salt. The difference in Shore D hardness between the inner and outer layers is within 5 Shore units. While maintaining superior flight performance and durability, the inventive ball presents a more pleasant feel.

    摘要： In a solid golf ball comprising a solid core, a cover inner layer and a cover outer layer, the cover inner layer is composed mainly of a thermoplastic elastomer free of an ionomer resin, and the cover outer layer contains 50-100% by weight of an ionomer resin. The difference in Shore D hardness between the inner and outer layers is within 2 Shore units. While maintaining superior flight performance and durability, the inventive ball has spin receptivity close to wound golf balls.
