Three-piece solid golf ball.

摘要

A solid core (1) comprising an center (1a) and an outer shell (1b) coated with a cover (2) to give a three-piece solid golf ball. The center (1a) has a diameter of 30.7 to 39.5 mm, a stiffness of 300 to 2,500 kgf/cm<2> and a shore D hardness of 30 to 55. The outer layer core (1b) has a thickness of 1.0 to 4.0 mm, a stiffness of 2,500 to 6,000 kgf/cm<2> and a shore D hardness of 55 to 75. The composition of both cores is a butadiene rubber. The cover (2) has a thickness of 0.6 to 2.0 mm, a stiffness of 1,000 to 2,500 kgf/cm<2> and a shore D hardness of 40 to 55. The composition of the cover is an ionomer resin or a mixture of the ionomer resin and a flexible resin.
