<p><P>PROBLEM TO BE SOLVED: To provide a golf ball capable of suppressing the amount of backspin for a hitting by a club with a small loft angle and increasing the amount of backspin for the hitting by a club with a large loft angle. <P>SOLUTION: This golf ball is provided with a golf ball body and a coating film covering the golf ball body, and the coating film contains metal particles. When the dynamic friction coefficient of the golf ball is enlarged by allowing the coating film covering the golf ball body to contain the metal particles, this golf ball can increase the amount of backspin to the hitting by the club with the large loft angle and suppress the amount of backspin to the hitting by the club with the small loft angle. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
