Abstract
A multi-piece solid golf ball has a solid core of multi-layer configuration including an inner layer circumscribed by an outer layer. The core inner layer is formed from a rubber composition. The core outer layer is formed thereon by injection molding a mixture of 100-50 wt % of a polyether ester type thermoplastic elastomer having a Shore D hardness of 30-50 and a Tg of up to -25.degree. C. and 0-50 wt % of an ethylene-(meth)acrylate copolymer ionomer having a flexural modulus of 200-400 MPa. The core is surrounded by a cover of an ethylene-(meth)acrylate copolymer ionomer having a flexural modulus of 200-450 MPa and a Shore D hardness of 55-68. The ball shows improved flying performance, feel on impact and durability and lends itself to mass production.
