发明名称 MULTI-LAYER GOLF BALL
摘要 Multi-layer golf balls having a soft, low compression center; a soft, flexible outer cover layer; and a relatively hard, high compression intermediate layer disposed between the center and the outer cover layer are provided. The outer surface hardness of the intermediate layer is greater than that of both the center and the outer cover layer.

主权项 1. A golf ball consisting essentially of: a center having a diameter of less than 1.500 inches, a compression of from 5 to 40, and formed from a polybutadiene composition; an outer cover layer formed from a composition having a flexural modulus of 40,000 psi or less; an intermediate layer disposed between the center and the outer cover layer, the intermediate layer having an outer surface hardness of greater than 60 Shore D and being formed from a thermoplastic composition having a solid, single core compression of 60 or greater; wherein the outer surface hardness of the center and the outer surface hardness of the outer cover layer are less than the outer surface hardness of the intermediate layer; and wherein the solid, single core compression of the intermediate layer is at least 25 compression points higher than the compression of the center.
