Abstract
In a golf ball having a core and a cover of at least one layer, the outermost layer of the cover is formed of a resin composition that includes (A) 100 parts by weight of a thermoplastic resin, and (B) 1 to 30 parts by weight of a compound having a fluorene skeleton, or a derivative thereof, and the resin composition has a melt flow rate of at least 3.0 g/10 min. This resin composition for golf balls has an improved injection-moldability and thus enables the ball to achieve both a reduced spin rate and a good durability (scuff resistance).
