ABSTRACT:
Provided is a golf ball with a transparent cover made of ionomer resin containing 0.02% or less of a pigment or a dyestuff. The surface of the cover of the golf ball is processed using a corona discharge process at a voltage of 90,000V and then together with wedge type grinding media in a revolving hexagonal drum type surface treatment machine to induce microscopic indentations and scratches on the surface of the cover. An anchor coated layer is formed on the surface of the cover using acrylic resin or urethane resin, and a top coated layer is formed on the anchor coated layer using urethane resin. The surface of the golf ball has a number of specula surfaces and thus can induce diffused reflections of light. Therefore, the golf ball appears in dual color due to the color of its core and the color of shadows of dimples. In addition, when the golf ball has circular dimples, the shadows of edges of the circular dimples are revealed as irregular round polygons and are in discord with the original positions of the dimples. Therefore, the golf ball can be easily discriminated even at a distance when landing on the ground in a golf course.
