ABSTRACT:
The invention provides a golf ball comprising a core and a cover of one or more layers, characterized in that at least one layer which constitutes the cover is formed primarily of a mixture of (A) a thermoplastic resin composition selected from among a thermoplastic block copolymer, polyester base elastomer, polyamide base elastomer and polyolefin, which are modified with functional groups having reactivity with isocyanate, and (B) an isocyanate compound or an isocyanate mixture having at least two isocyanate groups as functional groups in a molecule, and a method for preparing the same. The golf ball has excellent flight performance, feel on impact, and scuff resistance.
