    摘要： A golf ball including an inner core having a geometric center and a first outer surface, the inner core being formed from a first substantially homogenous rubber composition, and an outer core layer formed from a second substantially homogenous rubber composition, the outer core layer having a second outer surface. An inner cover layer is formed over the core and includes an ionomeric material. An outer cover layer is formed over the inner cover layer and includes a castable polyurea or a castable polyurethane. The first outer surface has a hardness of up to about 20 Shore C less than a hardness at the geometric center to define a negative hardness gradient inner core and the second outer surface has a hardness of up to 18 Shore C greater than the geometric center hardness to define a positive gradient outer core layer and a shallow positive hardness gradient core.

    摘要： Golf balls having a multi-layer core and a cover are disclosed. The multi-layer core contains a center and an outer core layer that are both soft relative to a hard intermediate core layer. The outer core layer is thin relative to the center and outer core layer. In one embodiment, the relatively hard intermediate core layer has a surface hardness of 80 to 90 Shore C which is greater than the center hardness and surface hardness of the outer core layer. In another embodiment, the cover includes an inner cover layer having a surface hardness of 60 Shore D or greater and an outer cover layer having a surface hardness of 20 to 70 Shore D.

    摘要： The present invention is directed to an improved golf ball displaying the desired spin profile and having a generally rigid, thermoset polybutadiene outer core surrounding a relatively soft, low compression inner core. In general, this golf ball has an inner core and at least one outer core layer surrounding the inner core. The inner core has a hardness less than a hardness of the outer core and a specific gravity less than or equal to the outer core specific gravity. Overall the inner core compression and outer core are formulated to provide a combined overall core compression of greater than about 50, preferably greater than about 70. A cover layer is provided to surround and to cover the outer core layer.
