Abstract: The invention is directed to a UV light resistant, visibly transparent, urethane golf ball topcoat composition for use with UV curable inks and to golf balls incorporating such a topcoat. The topcoat includes an optical brightener that absorbs at least some ultraviolet light at wavelengths greater than about 350 nm, and emits visible light, and a light stabilizer package. The light stabilizer package includes at least one UV light absorber and, optionally, at least one light stabilizer, such as a HALS. The UV light absorber absorbs at least some UV light at wavelengths between about 200 nm and about 370 nm, and has an absorption peak at a wavelength between about 330 nm and about 360 nm and a UV light absorbance at a wavelength of about 350 nm that is at least about 3 times greater than the UV light absorbance at a wavelength of about 370 nm.
