Abstract
A golf ball providing resistance to abrasion and resistance to wear generally in an excellent balance is formed of a core and a cover arranged to cover the core, the cover being formed of a compound containing relative to 100 parts by mass of a polymer component thereof composed mainly of polybutadiene rubber 1-40 parts by mass of a reinforcement material formed of organic short fiber and 10-40 parts by mass of a metallic salt of α,β-ethylene unsaturated carboxylic acid. It is characterized in that the organic short fiber is suitably a ternary composite formed of a rubber component, a polyolefin component and a nylon component and the metallic salt of α,β-ethylene unsaturated carboxylic acid is suitably zinc acrylate, zinc methacrylate, magnesium acrylate or magnesium methacrylate.
