Patent ID: 6962951

Claim:
A solid golf ball comprising a solid core of at least one layer and a cover of at least one layer enclosing the solid core, wherein an outermost layer of the cover is made of a golf ball material comprising a heated mixture having a melt index of at least 1.0 dg/min, consisting essentially of: (A) 100 parts by weight of a base resin comprising a mixture of (A1) an olefin-unsaturated carboxylic acid-unsaturated carboxylate random copolymer, or both of an olefin-unsaturated carboxylic acid random copolymer and an olefin-unsaturated carboxylic acid-unsaturated carboxylate random copolymer, and (A2) a metal ion-neutralized olefin-unsaturated carboxylic acid-unsaturated carboxylate random copolymer, or both of a metal ion-neutralized olefin-unsaturated carboxylic acid random copolymer and a metal ion-neutralized olefin-unsaturated carboxylic acid-unsaturated carboxylate random copolymer; (B) 5 to 20 parts by weight of a fatty acid or fatty acid derivative having a molecular weight of at least 280; and (C) 0.1 to 10 parts by weight of a basic inorganic metal compound capable of neutralizing acidic groups in components A and B, wherein the basic inorganic metal compound of component (C) is selected from the group consisting of calcium oxide, magnesium oxide, sodium hydroxide and calcium hydroxide.
