Abstract:
1. A golf ball comprising: a core having a diameter of less than 1.500 inches, an overall compression of greater than 60, and comprising two layers formed from the same or different highly neutralized polymer compositions; an outer cover layer formed from an ionomer composition, the ionomer composition having a flexural modulus of greater than 40,000 psi and a material hardness of greater than 60 Shore D; an intermediate layer disposed between the core and the outer cover layer, the intermediate layer having an outer surface hardness of less than 60 Shore D and being formed from a polyurea composition; wherein the outer surface hardness of the intermediate layer is less than that of both the core and the outer cover layer; and wherein a first golf ball subassembly consisting of the core, the intermediate layer, and any optional layers disposed between the core and the intermediate layer has a first compression; a second golf ball subassembly consisting of the core and the optional layers disposed between the core and the intermediate layer has a second compression; the first compression is less than the second compression; and the difference between the first compression and the second compression is at least 20 compression points.
