    Abstract: A 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.

    Abstract: A golf ball includes a single core having an outer surface and a geometric center. The core is formed from a substantially homogenous rubber composition. An inner cover layer is disposed about the core, the inner cover including a high-acid ionomer and having a material hardness of about 66 to 75 Shore D. The high-acid ionomer has an acid content of about 16% or greater. An outer cover layer is disposed about the inner cover layer, the outer cover including a polyurethane and having a material hardness of about 38 Shore D to about 56 Shore D. The core surface hardness is from 0 Shore C to 15 Shore C lower than the geometric center hardness to define a hardness gradient.

    Abstract: Golf ball comprising core; casing layer; cover layer; and plurality of outer coating layers. Casing layer comprises an ionomer blend of at least one ionomer and a color concentrate resin that is included in an amount of 3-10 wt. % of the ionomer blend. Cover layer is transparent and comprises thermoplastic/thermoset urethane composition. First outer coating layer is adjacent to cover layer and comprises clear water-borne or solvent-borne primer; and second outer coating layer is adjacent to first outer coating layer and comprises gold pearl primer, white sparkle primer, or combination thereof; third outer coating layer is adjacent to second outer coating layer and comprises a clear topcoat. Alternatively, second outer coating layer comprises matte topcoat, clear glossy topcoat, or combination thereof. In all embodiments, first outer coating layer and/or second outer coating layer may be colorless.
