The solid core has a deformation, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of 2.0 to 4.0 mm, and has a specific hardness distribution. The cover layer is formed by injection molding a single resin blend composed primarily of (A) a thermoplastic polyurethane and (B) a polyisocyanate compound, which resin blend contains a polyisocyanate compound in at least some portion of which all the isocyanate groups on the molecule remain in an unreacted state, and has a thickness of 0.5 to 2.5 mm, a Shore D hardness at the surface of 50 to 70. The golf ball has a deformation, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of 2.0 to 3.8 mm. The solid golf ball is advantageous overall in competitive use.

摘要： The invention provides a method of manufacturing golf balls having a core and at 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 golf balls thus obtained have a high rebound and excellent scuff resistance.
