Golf ball

Abstract

A golf ball includes a solid core, and a cover having one layer or two or more layers provided to directly cover the solid core or cover the solid core via an intermediate layer. At least one layer of the cover is taken as a high hardness cover layer which is made from a base resin containing an inorganic filler in an amount of 5 to 40 parts by weight on the basis of 100 parts by weight of the base resin and which has a Shore D hardness in a range of 66 to 80. With this configuration, the golf ball can exhibit a high carrying performance, a desirable very soft feeling of hitting, and an excellent durability against continuous hitting.

1 . A golf ball comprising: 
 a solid core; and    a cover having one layer or two or more layers provided to directly cover said solid core or cover said solid core via an intermediate layer;    wherein at least one layer of said cover is taken as a high hardness cover layer which is made from a base resin containing an inorganic filler in an amount of 5 to 40 parts by weight on the basis of 100 parts by weight of said base resin and which has a Shore D hardness in a range of 66 to 80.    
     
     
         2 . A golf ball according to  claim 1 , wherein said high hardness cover layer is an outermost cover layer.  
     
     
         3 . A golf ball according to  claim 1  or  2 , wherein said base resin for forming said high hardness cover layer has a Shore D hardness in a range of 65 or more.  
     
     
         4 . A golf ball according to any one of  claims 1  to  3 , wherein the Shore D hardness of said high hardness cover layer is higher than the Shore D hardness of said base resin by 1 or more.  
     
     
         5 . A golf ball according to any one of  claims 1  to  4 , wherein said inorganic filler contained in said high hardness cover layer is titanium dioxide and/or barium sulfate.  
     
     
         6 . A golf ball according to any one of  claims 1  to  5 , wherein said high hardness cover layer contains titanium dioxide as said inorganic filler in an amount of 2 parts by weight or more.  
     
     
         7 . A golf ball according to any one of  claims 1  to  6 , wherein a deformed amount of said solid core, measured by applying a load of 980 N thereto, is in a range of 4.0 to 6.5 mm.
