    • PROBLEM TO BE SOLVED: To achieve a multi-layer golf ball having single layer core that has a shallow soft-to-hard ("positive") hardness gradient, from the surface to the center.SOLUTION: The golf ball includes a single core formed from a substantially homogenous rubber composition, an inner cover disposed about the core, and an outer cover. The inner cover includes an ionomeric material and has a hardness of about 60 Shore D or greater. The outer cover layer is disposed about the inner cover layer, is formed from a castable polyurea or polyurethane, and has a material hardness of about 60 Shore D or less. The outer surface of the core has a trans content of about 12% or less and a hardness of about 71 to 88 Shore C, the geometric center of the core has a trans content of about 10% or less and a hardness of about 70 to 80 Shore C, and the core surface hardness is greater than the geometric center hardness by about 1 to 10 Shore C to define a shallow positive hardness gradient.

    • PROBLEM TO BE SOLVED: To provide a golf ball cover having an excellent mechanical strength and cut/shearing resistance and furthermore light stability. SOLUTION: A golf ball 20 including a cover material made of a polyurea composition is provided. In one version, the golf ball 20 includes a polybutadiene core 22 and a coating cover layer 24 made of the polyurea composition. In another version, the golf ball 20 includes the polybutadiene core 22, an intermediate casing layer made of an ionomer resin and an outer cover layer 24 made of the polyurea composition. The polyurea composition is the reaction product of alycyclic isocyanate and amine compound. Diisocyanate is selected from 1,3-bis(isocyanatomethyl)cyclohexane, 1,4-bis(isocyanatomethl)cyclohexane and the mixture thereof. The resulting cover material has many advantageous characteristics including improved durability, toughness and light stability. COPYRIGHT: (C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a golf ball that solves many problems associated with previous attempts at hollow core constructions by combining a hollow core construction with variations in the hardness of adjoining thermoplastic and/or thermoset core layers.SOLUTION: A golf ball includes a spherical inner core shell layer formed from a curable rubber composition, the shell layer having an outer surface, an inner surface, and an inner diameter to define a hollow center. A thermoplastic outer core layer is formed about the shell layer. An optional inner cover layer is formed about the outer core layer, the inner cover layer including an ionomeric material. An outer cover layer is formed over the core or optional inner cover layer, the outer cover layer including a polyurea or a polyurethane and having a second hardness less than that of the optional inner cover layer. The hollow center has a diameter of about 0.15 to 1.1 inches.
