Abstract
The present invention is directed to a golf ball having a dual, or multilayer core component that is relatively soft and a hard cover that results in the golf ball exhibiting a reduced spin rate. The dual, or multilayer core component includes a center component and a core layer, each of which is independently formed from a thermoset material, a thermoplastic material, or a blend thereof. The dual core component is relatively soft, having a Riehle compression of at least 75. The cover is preferably formed from a high acid ionomer or a certain type of alpha-olefin such that the cover has a Shore D hardness of at least 65. The cover may be a single layer cover or a multilayer cover. The golf ball of the present invention may have an enlarged diameter which serves to further reduce spin rate. The resulting golf ball exhibits properties of reduced spin without sacrificing durability, playability and resilience.
