ABSTRACT:
The invention provides a golf ball composed of a core, an intermediate layer which encases the core, and a cover which encases the intermediate layer. The core has a diameter of 36 to 40 mm and a deflection of 3.5 to 4.2 mm, and the intermediate layer has a Shore D hardness of 45 to 55 and a thickness of 0.6 to 1.6 mm. The cover has a Shore D hardness of 63 to 66 and a thickness of 0.6 to 1.6. The ball as a whole has a deflection of 2.6 to 3.5 mm, and the intermediate layer and cover have a combined thickness of 1.8 to 2.8 mm. The ball has a hardness design such that the Shore D hardnesses of the ball components satisfy the relationshipin-line-formulae description="In-line Formulae" end="lead"?core center≦core surface≦intermediate layer≦cover,in-line-formulae description="In-line Formulae" end="tail"?and the cover is made of a material composed primarily of a thermoplastic resin or a thermoplastic elastomer. The intermediate layer is made of a material that is a resin composition in which at least 90 mol % of the acid groups are neutralized. This combination of characteristics provides the golf ball with a sufficient spin rate-lowering effect, thus increasing the distance traveled, and also confers the ball with a good feel on impact and an excellent durability to cracking.
