Golf ball resin composition and golf ball using the same

Abstract

An object of the present invention is to provide a golf ball traveling a great flight distance on driver shots. The present invention provides a golf ball wherein at least one constituting member therefore is formed from a golf ball resin composition containing: (A) a polyamide resin and (B) at least one member selected from the group consisting of (b-1) a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms, (b-2) a metal ion-neutralized product of a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms, (b-3) 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 (b-4) 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, wherein the content of (A) component with respect to 100 mass % of a total of (A) component and (B) component is 15 mass % to 80 mass %, a slab hardness of the golf ball resin composition is 65 or more and 80 or less in Shore D hardness, and a value (X/A) obtained by dividing a flexural modulus X (MPa) by the content of (A) component (A: 15 mass % to 80 mass %) is 12.5 or more.
