Abstract:
1. A golf ball comprising a core and a cover formed of a cover resin composition, wherein said core has a hardness corresponding to a compressive deflection amount of at least 3.5 mm when the load applied thereto is increased from an initial load of 10 kgf to a final load of 130 kgf, said cover resin composition has a melt flow rate of at least 3 as measured according to JIS K7210, and said cover has a gage of up to 1.7 mm, and wherein said cover resin composition comprises (a) at least one component selected from the group consisting of olefin-unsaturated carboxylic acid copolymers, olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester copolymers, and metal ion-neutralized products of these copolymers and (b) a binary copolymer consisting of polyolefin and polyamide components in admixture as a resin component.
