Abstract
The invention provides a golf ball material which is a resin mixture composed of (a) a nonionic olefin-unsaturated carboxylic acid copolymer and/or olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester copolymer, (b) a nonionic olefin-unsaturated carboxylic acid copolymer and/or olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester copolymer, (c) an organic acid or a metal salt thereof, (d) a basic inorganic metal compound for neutralizing at least 70 mol % of acid groups in components (a) to (c), and (e) a spherical inorganic filler, which resin mixture has a Shore D hardness of from 40 to 60. The golf ball material of the invention provides an excellent rebound resilience and durability while maintaining the flow properties essential for injection molding.
