Colored, transparent coating layer for golf club head and golf club head members

Abstract

A golf club head includes a metal surface and at least one colored, transparent coating layer formed thereon. The colored, transparent coating layer contains a resin material and a coloring material. The colored, transparent coating layer exposes the metal surface of the golf club head in the coloring material that enhances the appearance of the golf club head. In an embodiment, the colored, transparent coating layer includes a first colored layer and a second colored layer. The first colored layer and the second colored layer vary in colors, or the colors of the first colored layer and the second colored layer vary in depth.

       8 . The golf club head as defined in  claim 7 , wherein the bottom primer layer is made from a transparent resin or a translucent resin. 
   
   
       9 . The golf club head as defined in  claim 1 , wherein a protective layer is formed on the colored, transparent coating layer. 
   
   
       10 . The golf club head as defined in  claim 9 , wherein the protective layer is made from a transparent resin or a translucent resin. 
   
   
       11 . The golf club head as defined in  claim 1 , wherein the colored, transparent coating layer includes a first colored layer and a second colored layer. 
   
   
       12 . A golf club head member, said golf club head member selected from one of a striking plate, a crown plate, a blade portion, a skirt wall, a rear wall, a sole plate, a neck section and a hosel of a golf club head, comprising:
 a metal surface provided on the golf club head member, said metal surface having a predetermined portion; and   at least one colored, transparent coating layer formed on the predetermined portion of the metal surface, said colored, transparent coating layer containing at least one resin material and at least one coloring material;   wherein the colored, transparent coating layer exposes a metallic luster from the metal surface in color.   
   
   
       13 . The golf club head member as defined in  claim 12 , wherein the resin material of the colored, transparent coating layer is selected from the group consisting of polyurethane elastomer, epoxy, acrylic resin, polyurethane resin, nitro-lacquer resin, polyester resin, phenolic aldehyde resin and alkyd resin. 
   
   
       14 . The golf club head member as defined in  claim 12 , wherein the resin material of the colored, transparent coating layer is selected from a transparent resin or a translucent resin. 
   
   
       15 . The golf club head member as defined in  claim 12 , wherein a lacquer thinner is contained in the colored, transparent coating layer.
