<p>A golf ball (24) includes first, second and third clear coats (26, 28, 30) on its cover (14). The second clear coat (28) contains an effective amount of an optical brightener. The first and third clear coats (28, 30) a trace of optical brightener. In a second embodiment of the invention, small quantities of optical brightener are included in the first and third clear coats (26, 30), in amounts less than that which causes degradation of their physical properties. In a further embodiment of the invention, an optical brightener is included in the cover (14) of the golf ball (24). In a still further embodiment of the invention, a paint layer (34) on the cover (14) is coated with first, second and third clear coats. At least two of the paint layer, the first clear coat, the second clear coat and the third clear coat contain an effective amount of an optical brightener and the remainder contain no more than a trace amount of optical brightener. <IMAGE></p> |
