Abstract
The present invention provides a resin composition for a golf ball and a golf ball which have high resilience while maintaining soft compression and also have low spin on driver shots, and therefore can achieve a long flight distance. The present invention relates to a resin composition for a golf ball, including an ionomer resin consisting of a metal ion-neutralized copolymer of (A) a Cα,β-unsaturated carboxylic acid and (B) a Cα,β-unsaturated carboxylic acid ester, the ionomer resin having a mass ratio of (A)/(B) of 10/90 to 25/75, and a degree of neutralization of 30 to 105 mol %.
