Patent

CA 2116398

A golf ball with a visible outer layer containing a blend of about 0.01 - 0.05 parts by weight of a thiophene-type optical brightener and about 0.008 - 0.025 parts by weight of a second optical brightener selected from the group consisting of 2,2'-(1,2-ethenediyldi-4,1- phenylene)bisbenzoxazole and derivatives thereof, the parts by weight of optical brightener being based upon 100 parts by weight of the polymeric material. The blend provides for a degree of whiteness comparable to that of 0.1 parts by weight of a thiophene-type optical brightener used alone, and provides for better solubility than results from the use of higher concentrations of 2,2'-(1,2-ethenediyldi- 4,1-phenylene)bisbenzoxazole alone.
