GOLF BALL
An improved golf ball comprises a core with a coarse surface, a resin layer bonded to the coarse surface of the core, a reflective layer being a metal thin film with a glossy surface and coated on the resin layer by vacuum plating, and a transparent layer coated on the reflective layer. Through illumination of light, the reflective layer of the golf ball can reflect the light to glisten brighter after the golf ball is hit. The reflective layer also is less likely to be peeled off, atomized and damaged after the golf ball is hit, thus can increase the lifespan thereof.
1 . A golf ball, comprising:
a core including a coarse surface;
a resin layer bonded to the coarse surface of the core;
a reflective layer which is a metal thin film with a glossy surface and coated on the resin layer by vacuum plating; and
