ABSTRACT:
A golf ball or similar game ball is made by providing an ionomer cover and a polyurethane top coat and uniting them with a special primer. First, a cover made of thermoplastic ionomer is provided. The cover is primed with a primer composition consisting essentially of from about 90% by weight to about 96% by weight of a water-borne dispersion of acrylic resin or polyurethane resin or both and from about 4% to about 10% by weight of a polyfunctional aziridine. The primed surface of the cover is coated with a polyurethane top coat. The polyurethane top coat is applied to the primed surface, forming an outer coating or top coat. Finally, the polyurethane top coat is cured while it remains in adherent relation to the primed surface. As a result, the golf ball polyurethane top coat is tightly adhered to the cover of the ball.
