Abstract

In a golf ball having a core of at least one layer and a cover of at least one layer, at least one core or cover layer contains a butyl rubber ionomer. A method of manufacturing golf balls having a core of at least one layer and a cover of at least one layer includes the steps of preparing a treatment solution of butyl rubber ionomer dissolved in a solvent, applying the treatment solution to at least one layer of the golf ball, and covering the treated layer with, as an outer layer adjoining thereto, a rubber layer, a resin layer or a paint layer. With this golf ball and golf ball manufacturing method, adhesion between the layers can be improved, enabling the durability of the ball to cracking on impact to be increased.
