Abstract
Disclosed herein is a method for producing golf balls which comprises surface-treating a golf ball with atmospheric pressure plasma prior to finish coating. The resulting golf balls have a coating film which is in good adhesion to the golf ball and highly resistant to discoloration and deterioration by heat, moisture, and light. The surface treatment is by the atmospheric pressure plasma which does not need the treating apparatus to be evacuated. The surface treatment under atmospheric pressure requires only a simple treating apparatus and can be applied to any golf balls without evaporating volatile matters contained therein.
