Patent ID: 10561903

Abstract:
In a golf ball having a core of at least one layer and a cover of at least one layer, an outermost layer of the cover is formed of an ionomer resin composition which includes specific amounts of (a) an olefin-α,β-unsaturated carboxylic acid copolymer and/or a metal ion neutralization product thereof, or an olefin-α,β-unsaturated carboxylic acid-α,β-unsaturated carboxylic acid ester copolymer and/or a metal ion neutralization product thereof, (b) an oxazoline group-containing polymer, (c) an inorganic filler, and (d) a colorant which includes a fluorescent dye or a fluorescent pigment. This golf ball has a translucent appearance that holds down transparency of the ball surface to a suitable level and undergoes relatively little change in color when fading occurs due to sunlight exposure, and is thus both weather resistant and decorative.
