Patent ID: 8501871

Claim:
A golf ball comprising: an outer core consisting of an inner core and one or more intermediate layers covering the inner core; and a cover covering the outer core, wherein the inner core consists of a center and a surrounding layer disposed outside the center, and the inner core has a surface hardness H 4 which is equal to or less than the surface hardness H 6 of the outer core, and the cover has a hardness H 7 of 50 or less in Shore D hardness, wherein the intermediate layer is formed from a highly elastic intermediate layer composition that contains (A) a highly elastic polyamide resin having a flexural modulus in a range from 700 MPa to 5,000 MPa; (B) a metal-neutralized product of ethylene-(meth)acrylic acid copolymer in an amount ratio ((A)/(B)) of (A) the highly elastic polyamide resin to (B) the metal-neutralized product of ethylene-(meth)acrylic acid copolymer being (20 mass % to 80 mass %)/(80 mass % to 20 mass %) (the total is 100 mass %); and (C) a resin having a polar functional group in an amount of 0.1 part by mass to 20 parts by mass with respect to 100 parts by mass of the sum of (A) the highly elastic polyamide resin and (B) the metal-neutralized product of ethylene-(meth)acrylic acid copolymer.
