Golf ball
Abstract:
In a golf ball having a core, a cover and at least one intermediate layer therebetween, the cover is formed of a rubber composition which includes a diene rubber, methacrylic acid, a metal oxide and an organic peroxide. The cover has a specific Poisson's ratio, Shore D hardness and thickness. At least one intermediate layer has a specific Shore D hardness and thickness. This golf ball, even with the use of a rubber cover, compares favorably with balls having conventional resin covers, both in that it can achieve a lower spin rate on shots with a driver (W #1) and thus has an excellent flight performance and also in that it can improve controllability in the short game.
