Patent ID: 7901300

Claim:
A multi-piece solid golf ball comprising a center, an intermediate layer formed on the center and a cover covering the intermediate layer, wherein the intermediate layer consists essentially of a single material having a flexural stiffness of 700 to 1,200 MPa, selected from the group of chemicals consisting of: polyurethane-based thermoplastic elastomer, polycarbonate resin, and polyacetal resin, wherein the cover is formed from a polyurethane-based thermoplastic elastomer, wherein the center is formed from a rubber composition which comprises a peptizing agent in an amount of 0.1 to 2.0 based on 100 parts by weight of a base rubber, and the center has a deformation amount of 3.0 to 6.0 mm when applying from an initial load of 98 N to a final load of 1275 N, and wherein the golf ball has a deformation amount of 2.4 to 3.5 mm when applying from an initial load of 98 N to a final load of 1275 N.
