Abstract
An object of the present invention is to provide a golf ball resin composition containing an ionomer resin with an excellent resilience and fluidity. Another object of the present invention is to provide a golf ball using an ionomer resin for an intermediate layer, with an excellent shot feeling, durability and resilience. The present invention provides a golf ball resin composition comprising (A) an ionomer resin consisting of a metal ion-neutralized product of a ternary copolymer composed of an olefin, an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and an α,β-unsaturated carboxylic acid ester; (B) a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and/or a ternary copolymer composed of an olefin, an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and an α,β-unsaturated carboxylic acid ester, and (C) a zinc compound, wherein a content ratio ((A)/(B)) of (A) component to (B) component ranges from 50/50 to 80/20 in a mass ratio and a content of (C) component ranges from 0.1 part to 20 parts with respect to 100 parts by mass of a sum of (A) component and (B) component, and the golf ball resin compositio…
