Golf ball

Abstract

The object of the present invention is to provide a golf ball having the individualized appearance as well as the improved visibility, which the mark should inherently provide, by imparting the luster (brilliance) to the mark, without lowering the durability of the mark. The golf ball of the present invention comprises a mark on a golf ball body, wherein the mark is made from an ink composition that comprises a luster material including a bismuth-containing compound, and a pigment.

1 . A golf ball comprising a mark on a golf ball body,
 wherein the mark is made from an ink composition that comprises   a luster material including a bismuth-containing compound, and   a pigment.   
     
     
         2 . The golf ball according to  claim 1 , wherein the bismuth-containing compound is bismuth oxychloride. 
     
     
         3 . The golf ball according to  claim 1 , wherein the ink composition comprises the luster material in an amount ranging from 1 mass % to 30 mass %. 
     
     
         4 . The gold ball according to  claim 1 , wherein the ink composition further comprises an ultraviolet absorber and/or a light stabilizer. 
     
     
         5 . The golf ball according to  claim 1 , wherein the luster material comprises a core layer of the bismuth-containing compound and at least one covering layer covering the core layer. 
     
     
         6 . The golf ball according to  claim 5 , wherein the covering layer comprises a metal compound selected from the group consisting of titanium oxide, cerium oxide and cerium hydroxide. 
     
     
         7 . The golf ball according to  claim 1 , wherein the luster material has a number average particle size ranging from 1 μm to 25 μm. 
     
     
         8 . The golf ball according to  claim 1 , wherein the luster material has an average thickness ranging from 0.5 μm to 5 μm. 
     
     
         9 . The golf ball according to  claim 1 , wherein the ink composition contains the pigment in an amount ranging from 0.5 mass % to 20 mass %. 
     
     
         10 . The golf ball according to  claim 1 , wherein a content ratio of the luster material to the pigment (luster material [mass %]/pigment [mass %]) ranges from 0.5 to 50. 
     
     
         11 . The golf ball according to  claim 1 , wherein the ink composition contains an ultraviolet absorber in an amount ranging from 0.01 mass % to 10 mass %. 
     
     
         12 . The golf ball according to  claim 1 , wherein the ink composition contains a light stabilizer in an amount ranging from 0.1 mass % to 10 mass %.
