| 摘要 |
An object of the present invention is to provide a golf ball showing an increased spin rate on approach shots under a wet condition while maintaining a spin rate on approach shots under a dry condition. The present invention provides a golf ball comprising a golf ball body and a paint film formed on a surface of the golf ball body, wherein the paint film has a multi-layered construction composed of two or more layers, and a difference (Min−Mout) between a 10% elastic modulus (Min) of an innermost layer of the paint film and a 10% elastic modulus (Mout) of an outermost layer of the paint film is 25 kgf/cm2 or more. |
