IMPROVED MULTI-LAYER GOLF BALL

摘要

The present invention is directed to an improved multi-layer golf ball (18) comprising a core (10), an inner layer (14) and an outer cover layer (12). T he inner cover layer (14) is comprised of a high acid ionomer or ionomer blend which may or may not include a filler such as zinc-stearate. The outer cover layer (12) is comprised of a soft, very low modulus ionomer or ionomer blend , or a non-ionomeric thermoplastic elastomer such as polyurethane, polyester o r polyestermide. The resulting multi-layered golf ball (18) of the present invention provides for enhanced distance without sacrificing playability or durability when compared to known multi-layer golf balls.
