Golf ball

Abstract

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.

What is claimed is: 
     
         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   a transparent layer coated on the reflective layer;   wherein the reflective layer includes a continuous reflective surface in parallel with an outmost surface of the transparent layer.   
     
     
         2 . The golf ball of  claim 1 , wherein the core is made of rubber, plastics or a mixture of rubber and plastics. 
     
     
         3 . The golf ball of  claim 1 , wherein the resin layer is made of polyurethane. 
     
     
         4 . The golf ball of  claim 1 , wherein the reflective layer is formed at a thickness ranged from 1 to 30 μm. 
     
     
         5 . The golf ball of  claim 4 , wherein the metal thin film is made of an aluminum alloy. 
     
     
         6 . The golf ball of  claim 1  further including a colored transparent plastic film coated on the reflective layer. 
     
     
         7 . The golf ball of  claim 1 , wherein the transparent layer further includes fluorescent powder.
