1. Field of the Invention
The present invention relates to a golf ball with a cover wherein hit feeling and control property of the golf ball are improved.
2. Description of the Related Art
As a cover material of a golf ball, an ionomer resin has widely been used (e.g. Japanese Patent Kokai No. 49-49727, etc.), heretofore. Particularly, in almost all of two-piece golf balls using a solid core, the ionomer resin is used as a cover material.
The reason for this is that the ionomer resin is superior in durability, cut resistance and impact resilience and is easily processed. Furthermore, the Ionomer resin is cheap in comparison with other cover materials.
However, since the ionomer resin has very high hardness and stiffness, it is inferior in hit feeling and control property (easy spinning) in comparison with balata (transpolyisoprene), which is used as a cover base of a thread wound golf ball.
As a result, attempts to improving hit feeling and control property have been made by softening the ionomer resin with various means, however, satisfactory results are not obtained at present.
