Multilayer golf ball with a thin thermoset outer layer

A method of forming a multilayer golf ball comprising a cover, a core and at least one intermediate layer interposed between said cover and core, said multilayer ball having improved interfacial adhesion between its layers, wherein the method comprises:

• (a) forming a golf ball core;
• (b) forming a textured pattern on the interior surface of a mold cavity, wherein said pattern comprises a plurality of depressions having depths of about 2 to about 15 mils and draft angles less than about 10 degrees;
• (c) placing the core in said mold cavity;
• (d) forming an intermediate layer having a first shore D hardness on said core in said mold cavity, said intermediate layer having a textured surface profile integrally molded in the outer surface thereof, wherein said surface profile is a corresponding image of said pattern and comprises a plurality of peaks having heights of about 2 to about 15 mils;
• and
• (e) casting an outer cover layer with a castable liquid reactive material or reaction products thereof having a second shore D hardness less than the first shore D hardness and a thickness of less than 0.05 inches.
