ABSTRACT:
The golf ball of the present invention has a white core which has a bright, white outer surface and a relatively thin, translucent cover composed of SURLYN.RTM. having a thickness of about 0.06 inches or less. The translucent SURLYN.RTM. cover contains between 6% and 12% by weight photostorage material, of the type having components such as aluminum oxide, strontium oxide, calcium oxide, europium oxide and boron oxide. A brightly colored fluorescent dye at a concentration between 0.01% and 0.04% by weight can also be added to a SURLYN.RTM. cover material to produce a golf ball of the present invention that is brightly colored. When the golf ball of the present invention has no fluorescent dye in its cover, it is substantially white in appearance, is visible in daylight and after being charged by exposure to light, emits a long lasting bright glow of light for high visibility in the dark. When the golf ball of the present invention has an added preferred bright yellow fluorescent dye, it can be seen in daylight and twilight conditions as easily as a standard yellow ball and after being charged by exposure to light also emits a long lasting bright glow of light for high visibility in the dark.
