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 thermoset material formed from a castable, reactive liquid, said outer layer having a thickness of less than 0.05 inches and said inner cover layer comprises a high flexural modulus material. The golf balls of the present invention are believed to provide a "progressive performance" from driver to wedge.
[ We claim:] [1.] A golf ball comprising a cover and a core, wherein said cover is disposed about the core and said cover comprises:(a) an inner cover layer of a flexural modulus of at least about 65,000 psi; and(b) an outer cover layer having a Shore D hardness of greater than 30 to 60, having a th
[ We claim:] [1.] A golf ball comprising a cover and a core, wherein said cover is disposed about the core and said cover comprises:(a) an inner cover layer of a flexural modulus of at least about 65,000 psi; and(b) an outer cover layer having a Shore D hardness of greater than 30 to 60, having a thickness of less than 0.050 inches and comprising a thermoset material that includes at least one of a castable reactive liquid material and reaction products thereof.
