ABSTRACT:
A golf ball has a coating layer made of a thermoplastic resin and formed by hot-melt coating at the surface portion thereof. For example, a two-piece golf ball is produced by enclosing a solid core with a cover material; conducting mark stamping directly on the surface of the cover material; forming, by hot-melt coating, a transparent coating layer made of a thermoplastic resin as an outermost layer; and then conducting dimple processing. The coating has a thickness in the range of 15-700 .mu.m. The coating allows the dimples to be precisely shaped and sharp edged and can be given sufficient durability and functions to improve spin properties and travel properties.
