Abstract
The invention provides a multi-piece solid golf ball having a core, an outermost layer cover with a surface on which are formed a plurality of dimples, and one or more intermediate layer between the core and the cover. At least one intermediate layer and the outermost layer cover are each formed primarily of an ionomer-containing thermoplastic resin. The resin of which the outermost layer cover is formed contains up to 20 wt % of a ternary copolymer ionomer and has formulated therein from 0.1 to 5.0 parts by weight of short organic fibers per 100 parts by weight of the resin. The golf ball of the invention has a fully satisfactory flight performance and a good feel on impact. Moreover, it has an excellent durability to cracking on repeated impact and also an excellent scuff resistance.
