Abstract:
An object of the present invention is to provide a golf ball that can strike a good balance in approach performance under a rough condition and a wet condition while maintaining a flight distance on driver shots. 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 golf ball body has a spherical core, an intermediate layer covering the spherical core, and a cover covering the intermediate layer, and the paint film has a multi-layered construction composed of two or more layers, wherein a 10% elastic modulus (Pi10) of an innermost layer of the paint film is greater than a 10% elastic modulus (Po10) of an outermost layer of the paint film and a 10% elastic modulus (C10) of a material constituting the cover, and a thickness (Ti) of the innermost layer of the paint film is greater than a thickness (To) of the outermost layer of the paint film, a 10% elastic modulus (M10) of a material constituting the intermediate layer is greater than the 10% elastic modulus (C10) of the material constituting the cover, and a difference (Po10−C10) between the 10% elastic modulus (Po10) of the outermost layer of the paint film and the 10% elastic modulus (C10) of the material constituting the cover is −4.0 kgf/cm2 or more and 50 kgf/cm2 or less, and a Shore D hardness (Hc) of the material constituting the cover is 40 or less.
