Abstract
The object of the present invention is to provide a golf ball having a paint film which is obtained from an environment-friendly aqueous paint and is excellent in the adhesion and the wear-resistance. The gist of the present invention lies in improving the adhesion between the paint film obtained from the aqueous polyurethane paint and the surface of the golf ball body by first applying the aqueous liquid of the aqueous polycarbodiimide on the surface of the golf ball body, subsequently forming the primer layer comprising the aqueous polycarbodiimide, and then applying the aqueous polyurethane paint to form the paint film, while reducing the amount of solvent used in the aqueous paint for applying on the golf ball by using the polycarbodiimide liquid and the aqueous polyurethane paint.
