Patent ID: 8864605

Claim:
A colored golf ball comprising a core, a cover of two or more layers encasing the core, and a coat of paint applied to a surface of an outermost layer of the cover, wherein the outermost cover layer is formed of a resin composition comprising: (a) 100 parts by weight of a thermoplastic resin, (b) 5 parts by weight or less of a fluorescent color-containing color pigment and/or dye, and (c) 0.45 part by weight or less of titanium oxide; a layer adjoining an inner side of the outermost layer is formed of a resin composition comprising: 100 parts by weight of a resin component which includes (A) an ionic resin having a weight-average molecular weight (Mw) of at least 40,000 and a weight-average molecular weight (Mw) to number-average molecular weight (Mn) ratio (Mn/Mw) of at least 3.0, and having at least 70 wt % of unsaturated carboxylic acid present therein neutralized with metal cations, and (B) a thermoplastic resin other than component A in a component A to component B weight ratio (A/B) of from 100/0 to 10/90, and (C-1) 5 parts by weight or less of a color pigment or dye, and/or (C-2) from 1 to 20 parts by weight of a color masterbatch; and the ball has a surface luminance of from 5 to 100 cd/m 2 , wherein the paint coat comprises 100 parts by weight of a base resin, from 0.05 to 1 part by weight of a fluorescent whitener and 3 parts by weight or less of a polarizing pigment, and the fluorescent whitener and polarizing pigment have a weight ratio therebetween of from 0.05 to 5.0.
