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.

In a golf ball having a core composed of one or more layer, the outermost layer of the core is formed of a rubber composition containing an α,β-unsaturated metal carboxylate, and an envelope layer directly encasing the core is formed of a resin composition containing a thermoplastic resin having a structure that includes α,β-ethylenically unsaturated carboxylic acid copolymerization units. The infrared absorption spectra at surface sites on the outermost layer of the core, as measured by ATR FT-IR spectroscopy, satisfy a specific condition. The ball has an enhanced adhesion between the rubber-based core and the adjacent cover layer that is formed of an ionomer resin or other α,β-ethylenically unsaturated carboxylic acid copolymer-containing resin material.

An object of the present invention is to provide a golf ball having a decreased spin rate on driver shots. The present invention provides a golf ball comprising a spherical core and at least one cover layer covering the spherical core, wherein the spherical core is formed from a rubber composition containing (a) a base rubber, (b) two or more α,β-unsaturated carboxylic acids having 3 to 14 carbon atoms and having no substituent group at a carbon atom bonding to the carboxy group, and/or a metal salt thereof, and (c) a crosslinking initiator.

The present invention is directed to a golf ball having a cover in which the dimples have two distinct hardness regions. The cover of the present invention is formed from a castable formulation including at least one prepolymer that incorporates some degree of unsaturation in the backbone of the polymer, at least one curative, and at least one free radical initiator. The present invention also explores the methods of making such golf balls. The methods of the present invention allow for the production of a golf ball dimple with two distinct hardnesses to be formed using a single castable formulation.
