    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。
