Treatment for facilitating bonding between golf ball layers and resultant golf balls

Abstract

The present invention is directed towards a multilayer golf ball which comprises a core having a treated surface and a cover layer having a plurality of dimples, wherein the cover layer is disposed concentrically about the core and bonded to the core preferably without an adhesive. The multilayer golf balls may alternatively or additionally be formed such that at least one layer of the core has a treated surface and is bonded, preferably without an adhesive, to an adjacent layer. The golf balls may be prepared by forming a first portion of a golf ball, wherein the first portion has a surface, treating the surface of the first portion by any chemical or mechanical process that improves or facilitates adhesion of the treated surface to an adjacent surface to increase the adhesion thereof, and bonding at least a portion of a second portion concentrically about the surface of the portion.
