    摘要: The present invention is directed towards a multilayer golf ball which comprises a core, an inner cover layer and an outer cover layer, wherein the outer cover layer comprises a castable reactive liquid material having a shore D hardness less than the shore D hardness of the material forming the inner cover layer. The present invention also relates to golf balls having improved adhesion between adjacent layers, as well as method for making golf balls having such improved adhesion. In particular, the outer surface of the core, an intermediate layer(s) or both the core and the intermediate layer(s) has a textured surface profile integrally molded in the outer surface thereof so that the surface profile promotes interfacial adhesion.
