Abstract:
1. A golf ball resin composition comprising, a resin component and (C) a zinc compound, wherein the resin component consists of (A) an ionomer resin consisting of 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 and (B) a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms, wherein a content ratio ((A)/(B)) of (A) component to (B) component ranges from 50/50 to 80/20 in a mass ratio and a content of (C) component ranges from 0.1 part to 20 parts with respect to 100 parts by mass of a sum of (A) component and (B) component, and the golf ball resin composition has a melt flow rate (190° C., 2.16 kg) of 15 g/10 min or more and a slab hardness ranging from 61 to 70 in Shore D hardness, wherein (A) the ionomer resin has a melt flow rate (190° C., 2.16 kg) ranging from 0.1 g/10 min to 30 g/10 min, and wherein (B) the binary copolymer has a melt flow rate (190° C., 2.16 kg) ranging from 100 g/10 min to 1000 g/10 min.
