    摘要： An object of the present invention is to provide a golf ball having improved ball speed or aerodynamic performance on a rainy day or the like by controlling the formulation of the paint film. The present invention provides a golf ball comprising a golf ball body and a paint film covering the golf ball body, wherein a paint film surface of the golf ball has a water contact angle A1 of 70 ° or more and a water sliding angle B1 of less than 50 °. The present invention also provides a golf ball comprising a golf ball body and a paint film covering the golf ball body, wherein when a sheet consisting of a slab formed from a composition constituting a golf ball body surface and a coating film formed by applying a paint constituting the paint film on the slab is prepared, a coating film surface of the sheet has a water contact angle A2 of 90 ° or more and a water sliding angle B2 of less than 52 °.

    摘要： A golf ball is provided including a core (12), a cover (14) encasing the core and a coating (16) that comprises a resin applied to the outer surface of the cover. Particles (22) comprising a high density material are included in the coating such that the coating has a density at least twice that of the core's density or contributes at least 0.60% of the golf ball's total moment of inertia, and the coating has a micro surface roughness at least 1.75 times larger than the roughness of a comparative ball. A method of making a golf ball is also provided, including providing a spherical core, encasing the core with a cover, applying a resin to the outer surface of the cover, and adding a plurality of particles comprising a high density material to form a coating material that has a second density at least two times the first density.
