Golf ball resin composition and golf ball

A golf ball having a constituent member formed from a golf ball resin composition, wherein the golf ball resin composition comprises (A) at least one resin component selected from the group consisting of (a-1) a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms, (a-2) 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, (a-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 (a-4) an ionomer resin consisting of 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, and (B) a compound having an anionic part within a molecule thereof, provided that the golf ball resin composition further contains (C) a basic inorganic metal compound in the case of containing only (a-1) the binary copolymer and/or (a-3) the ternary copolymer as (A) the resin component, wherein with respect to a metal ion contained in the golf ball resin composition, (A) the resin component and (B) the compound having the anionic part within the molecule thereof, following coordinate energies obtained by ab initio molecular orbital calculation method using a basis function B3LYP/6-31G(d) satisfy a following expression:

• 0.3≦(A−C)/(B−C)≦0.6.
• Coordinate energy A (kcal/mol):
• coordinate energy between the metal ion and the anionic part of (B) component,
• Coordinate energy B (kcal/mol):
• coordinate energy between the metal ion and the carboxyl ion of (A) component,
• Coordinate energy C (kcal/mol):
• coordinate energy between the metal ion and the olefin of (A) component.
