摘要： The present invention provides a golf ball comprising a core and a cover covering the core, wherein the cover layer comprises a 3-dimensional shaped metal oxide having at least three needle-shaped parts. Blending the 3-dimensional shaped metal oxide into the cover layer enhances the rigidity of the resultant cover for the hardness thereof. In the case that the cover layer has the slab hardness of 57D or more in shore D hardness, this property can be used to enhance the resilience without lowering the shot feeling. On the other hand, in the case that the cover layer has the slab hardness less than 57D in shore D hardness, this property can be used to enhance the resilience without lowering the spin rate.
摘要翻译：本发明提供一种高尔夫球，其包括芯和覆盖芯的盖，其中覆盖层包括具有至少三个针状部分的三维成形金属氧化物。将三维形状的金属氧化物混合到覆盖层中，由此提高了所得到的盖的硬度的刚性。在覆盖层的硬度为S D的硬度为57D以上的情况下，能够提高回弹性而不降低拍摄感。另一方面，在覆盖层的肖氏D硬度具有小于57D的板坯硬度的情况下，该性能可以用于提高回弹性而不降低旋转速率。
