Abstract
In a golf ball composed of a core and a cover of one or more layer that encloses the core, at least one layer of the cover is composed of 100 parts by weight of a base resin, 1 to 7 parts by weight of titanium oxide, 0.002 to 0.4 part by weight of a blue pigment, and 0.0006 to 0.5 part by weight of a violet pigment. The weight ratio of the blue pigment to the violet pigment is from 1:99 to 99:1. A sufficient whiteness is imparted to the surface of the ball, and the ball has an excellent resistance to color fading.
