摘要：
The present invention is directed to golf balls comprising a fluid-filled center surrounded by an outer core, wherein the outer core comprises a layer formed from a relatively soft HNP composition and a layer formed from a relatively hard HNP composition. The present invention is not limited by which outer core layer is formed from the relatively soft HNP composition and which layer is formed from the relatively hard HNP composition, so long as both layers are present in the outer core of the golf ball. Relatively soft HNP compositions of the present invention have a Shore D hardness of 55 or less and comprise a highly neutralized acid copolymer. Relatively hard HNP compositions of the present invention have a Shore D hardness of 45 or greater and comprise a highly neutralized acid copolymer. The material hardness of the relatively soft HNP composition is less than the material hardness of the relatively hard HNP composition.
