    • PROBLEM TO BE SOLVED: To provide a golf ball capable of achieving advantages of a hard ball without impairing the controllability.SOLUTION: The golf ball includes a single layer core and a cover layer disposed around the single layer core. The single layer core further includes an inner core region disposed around the geometric center, an outer core region and an intermediate core region at least about 2 mm apart from the outer surface. The inner core region has a first hardness (IC), the outer core region has a second hardness (OC), and the intermediate core region has a third hardness (IMC) and a fourth hardness (IMC). The relationships in the hardness are represented by: (IMC) (IC) and (IMC)>(OC). The outer surface has a hardness (OS), and the geometric center has a hardness (GC) represented by the relationship (OS)>(GC) to define a positive hardness gradient.
    • 要解决的问题:提供一种能够在不损害可控性的情况下实现硬球的优点的高尔夫球。解决方案:高尔夫球包括单层芯和围绕单层芯设置的覆盖层。 单层芯还包括设置在几何中心周围的内芯区域,外芯区域和与外表面至少约2mm的中间芯区域。 内芯区域具有第一硬度(IC),外芯区域具有第二硬度(OC),中间芯区域具有第三硬度(IMC)和第四硬度(IMC)。 硬度的关系用下式表示:(IMC)<(IC),(IMC)<(OC),(IMC)>(IC)和(IMC)>(OC)。 外表面具有硬度(OS),并且几何中心具有由关系(OS)>(GC)表示的硬度(GC),以确定正硬度梯度。

    • PROBLEM TO BE SOLVED: To provide a golf ball with unique combinations of compression, feel, and spin. SOLUTION: The golf ball includes: a unitary core having a volume, an outer surface, a geometric center, and an outermost transition part adjacent to the outer surface, the core being formed from a substantially homogenous composition; and a cover layer. The outermost transition part is disposed between the core outer surface and the geometric center, the transition part has an outer portion congruent with the core outer surface, and comprises the outermost 45% of the core volume or less. Both a hardness of the core outer surface and a hardness within the outermost transition part are less than the hardness of the geometric center to define a negative hardness gradient.
