Abstract
An object of the present invention is to provide a golf ball resin composition excellent in shot feeling and resilience. The golf ball resin composition includes (A) at least one resin component selected from the group consisting of (a-1) a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms, (a-2) an ionomer resin consisting of a metal ion-neutralized product of the binary copolymer components, (a-3) a ternary copolymer composed of the binary copolymer components and an α,β-unsaturated carboxylic acid ester, and (a-4) an ionomer resin consisting of a metal ion-neutralized product of the ternary copolymer components; and (B) a basic metal salt of a fatty acid, and having a storage modulus E′ (Pa) and a loss modulus E″ (Pa) satisfying a following expression;log(E′/E″2)≧−5.84when measured in a tensile mode using a dynamic viscoelasticity measuring apparatus.
