ABSTRACT:
The present invention is directed to a golf ball comprising a core having a diameter of at least 1.5 inches, at least one inner cover layer encasing the core, and an outer cover layer encasing the inner cover layer. The inner cover layer has a thickness of from 0.005 inches to 0.05 inches and is formed from a material selected from polyamides, polyesters, fluoropolymers, silicones, ionomers, crosslinked rubbers, and mixtures thereof. The outer cover layer has a thickness of from 0.005 inches to 0.05 inches, is softer than the inner cover layer, and is formed from a composition comprising polybutadiene, an organosulfur compound, and a co-crosslinking agent.
