The invention provides a golf ball comprising a core of at least one layer, a cover of at least one layer, and optionally an intermediate layer therebetween, characterized in that at least one layer of the core, cover and intermediate layer is formed of a golf ball-forming resin composition comprising, in admixture, (A) 100 parts by weight of a polyether ester block copolymer composed primarily of (a) high-melting crystalline polymer segments made of crystalline aromatic polyester units and (b) low-melting polymer segments made of aliphatic polyether units and (B) 0.05&#x2013;10 parts by weight of a polyisocyanate compound. Using the golf ball-forming resin composition which has flexibility and high rebound resilience and is fully wear resistant, the inventive golf ball is improved in travel distance, feel, scuff resistance and impact durability.

Golf Ball

The invention provides a golf ball comprising a core of at least one layer, a cover of at least one layer, and optionally an intermediate layer therebetween, characterized in that at least one layer of the core, cover and intermediate layer is formed of a golf ball-forming resin composition comprising (A) 50&#x2013;95% by weight of a polyether ester block copolymer composed primarily of (a) high-melting crystalline polymer segments made of crystalline aromatic polyester units and (b) low-melting polymer segments made of aliphatic polyether units and (B) 5&#x2013;50% by weight of a thermoplastic polyurethane elastomer, the total of components (A) and (B) being 100 parts by weight, in admixture with (C) 0.05&#x2013;10 parts by weight of a polyisocyanate compound. The inventive golf ball is improved in travel distance, feel, scuff resistance and impact durability.
