| 1. A method for preparing a golf ball, comprising the steps of:
coating a layer of a primer composition comprising an aqueous resin having UV-curable functional groups in a molecule and
a crosslinker on the cover surface of a golf ball,
applying a UV-curable paint onto the layer, wherein the primer composition layer is not irradiated with UV radiation prior
to having the UV-curable paint applied thereon, and
irradiating the layers with UV radiation, thereby permitting both of the primer composition layer and the UV-curable paint
to cure at the same time.
