Three-piece solid golf ball

Abstract

In a three-piece solid golf ball comprising a center core, an intermediate layer and a cover. The center core is based on rubber, the intermediate layer is formed mainly of a thermoplastic polyester elastomer to a Shore D hardness of 30-55, and the cover is formed mainly of an ionomer resin to a Shore D hardness of 45-54. The cover has a thickness in the range of 1.0-3.0 mm, the intermediate layer has a thickness of 0.5-3.0 mm and the core a thickness of 30-41 mm. The intermediate layer has a specific gravity of at least 1.05. The golf ball has spin receptivity approximate to wound golf balls while maintaining superior flight and durability characteristic of solid golf balls.
