Golf ball and process for preparing the same

A golf ball comprising

• a core, and
• a cover covering the core,
• wherein the cover is formed from a cover composition which comprises
• a polyisocyanate,
• a polyol, and
• a urethane polyol-layered silicate composite treated with a urethane polyol having a secondary or tertiary amine structure in a molecule thereof, and
• the urethane polyol-layered silicate composite is such that the urethane polyol having the secondary or the tertiary amine structure is cationized at the portion of the secondary or tertiary amine structure and bonded to the layered silicate via electrostatic interaction.

A process for producing a golf ball comprising the steps of:

• cationizing a polyol having a secondary or tertiary amine structure in a molecule thereof,
• dispersing a layered silicate into the cationized polyol to obtain a polyol-layered silicate composite,
• mixing the polyol-layered silicate composite, a polyol, and a polyisocyanate to prepare a cover composition, and
• molding a cover from the cover composition.
