    Abstract: A golf ball includes a core having an outer surface and a geometric center. The core is formed from a substantially homogenous rubber composition. An ionomeric inner cover layer is formed about the core and has a material hardness of about 60 Shore D or greater. The golf ball includes an outer cover layer formed from a polyurea or a polyurethane and having a material hardness of about 60 Shore D or less. The outer surface of the core has a trans content of about 12% or less and a hardness of about 71 to 88 Shore C. The geometric center of the core has a trans content of about 10% or less and a hardness of about 60 to 80 Shore C. The core has an outer surface hardness greater than a geometric center hardness by about 5 to 19 Shore C to define a positive hardness gradient.

    Abstract translation: 高尔夫球包括具有外表面和几何中心的芯。 芯由基本均匀的橡胶组合物形成。 离型聚合物内覆盖层围绕芯形成，并且具有约60肖氏D或更高的材料硬度。 高尔夫球包括由聚脲或聚氨酯形成并且材料硬度为约60肖氏D或更低的外覆盖层。 芯的外表面的反式含量为约12％或更低，硬度为约71至88肖氏C。芯的几何中心的反式含量为约10％或更低，硬度为约60至 80肖氏C.芯具有大于几何中心硬度的外表面硬度约5至19肖氏C以确定正硬度梯度。

    Abstract: Dual component cores having positive hardness and compression gradients and golf balls including these cores are disclosed. The hardness, compression, and diameter relationships in the core assemblage components help to reduce the spin rate of the ball off the driver while still providing desirable performance characteristics in and around the green.
