摘要 |
A golf ball has a core (1) enclosed with a cover (2) wherein the cover (2) is embossed on its surface with dimples by compression molding in a mold and includes an innermost layer (3), an intermediate layer (4), and an outermost layer (5). The intermediate layer (4) and the outermost layer (5) are formed of a laminate film while the outermost layer (5) is made of a material which is smoothly releasable from the mold. The golf ball is readily removed from the mold at the end of molding and has a high precision of dimple geometry.
