    摘要： A golf ball comprising an inner core having an outer surface and a geometric center and being formed from a substantially homogenous composition such that the geometric center has a hardness of 56 to 80 Shore C and the outer surface has a hardness of 50 to 75 Shore C. An outer core layer is disposed about the inner core and has an outer surface having a hardness of 85 to 98 Shore C and an inner surface having a hardness of 68 to 78 Shore C and being formed from a second substantially homogenous rubber composition. A cover layer is disposed about the outer core layer. The hardness of the second outer surface is greater than the hardness of the inner surface to define a positive hardness gradient of +7 to +30 Shore C, and the hardness of the first outer surface is lower than the hardness of the geometric center to define a negative hardness gradient of −1 to −15 Shore C.

    摘要： A golf ball comprising an inner core having an outer surface and a geometric center and being formed from a substantially homogenous rubber composition, the rubber composition comprising a base rubber and a resorcinol such that the geometric center has a hardness of 50 to 60 Shore C and the outer surface has a hardness of 85 to 95 Shore C. An outer core layer is disposed about the inner core and has an outer surface having a hardness of 50 to 75 Shore C, an inner surface having a hardness of 51 to 76 Shore C, and is formed from a substantially homogenous composition. A cover layer is disposed about the outer core layer. The hardness of the inner core outer surface is greater than the hardness of the geometric center to define a positive hardness gradient of greater than 20 Shore C, and the hardness of the outer core outer surface is lower than the hardness of its inner surface to define a negative hardness gradient of −1 to −5 Shore C.

    摘要： A golf ball comprising a single layer core and a cover layer disposed about the single layer core, the single layer core being formed from a substantially homogenous formulation and comprising a geometric center and an outer surface, the single layer core further comprising an inner core region disposed about the geometric center, an outer core region adjacent the outer surface, and an intermediate core region disposed between the inner and outer core regions and extending radially from about 8 mm to about 18 mm from the geometric center. The single layer core has first, second and third hardnesses disposed within the inner core region, outer core region, intermediate core region, respectively, wherein the third hardness is greater than the first hardness and the second hardness, and a hardness of the outer surface is substantially the same as or lower than a hardness of the geometric center.
