Abstract
A multi-piece golf ball includes a core composed of a center, an envelope layer and at least one cover. The center is formed from a composition containing at least one resin component and a basic metal salt of a fatty acid. The resin component is selected from a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid, an ionomer resin consisting of a metal ion-neutralized product of a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid, a ternary copolymer composed of an olefin, an α,β-unsaturated carboxylic acid and an α,β-unsaturated carboxylic acid ester, and an ionomer resin consisting of a metal ion-neutralized product of a ternary copolymer composed of an olefin, an α,β-unsaturated carboxylic acid and an α,β-unsaturated carboxylic acid ester. The envelope layer is formed from a composition containing a thermoplastic resin and/or a thermoplastic elastomer as a resin component.
