摘要： The invention provides a golf ball having a core and one or more cover layer encasing the core, wherein at least one cover layer is formed by injection-molding a single resin composition of primarily (A) a thermoplastic polyurethane and (B) a polyisocyanate compound, and at least some polyisocyanate compound in which all the isocyanate groups on the molecule remain in an unreacted state is present in the resin composition. The golf ball has a high rebound, an excellent spin performance and an excellent scuff resistance, and the cover layer-forming resin composition has excellent flow properties and an excellent cover layer manufacturability.

摘要： The invention provides a method of manufacturing golf balls having a core and least one cover layer which involves injecting a molten cover resin material around a core so as to form a cover layer. The cover resin material is a single resin composition made up of (A) a thermoplastic polyurethane, (B) a polyisocyanate compound and (C) a thermoplastic elastomer other than the thermoplastic polyurethane in a weight ratio (A):(B):(C)=100: {2-50}: {0-50}, and is injected with from 10 to 99% of the total number of isocyanate groups in component B remaining in an unreacted state within the cover resin material. The method of the invention provides a high manufacturability and a good amenability to mass production, and the manufactured gold balls thus obtained have a high rebound and excellent scuff resistance.
摘要翻译：本发明提供一种制造具有芯和至少一个覆盖层的高尔夫球的方法，其包括将熔融的覆盖树脂材料注入到芯周围以形成覆盖层。覆盖树脂材料是由（A）热塑性聚氨酯，（B）多异氰酸酯化合物和（C）热塑性聚氨酯以外的热塑性弹性体以重量比（A）:( B）:( A）表示的单树脂组合物:( C）= 100：{2-50}：{0-50}，并且在覆盖树脂材料中以未反应状态保留的组分B中的异氰酸酯基总数的10至99％注入。本发明的方法提供了高的可制造性和良好的批量生产能力，并且由此获得的制造的金球具有高的回弹性和优异的耐擦伤性。
