Abstract:
The present invention is directed to an improved multi-layered core golf ball wherein each core layer comprises its own specific hardness gradient (positive, negative or a combination) in addition to an overall specific hardness gradient from one core layer to the next.
Abstract:
Method of making a golf ball, the golf ball comprising a core, an outer layer and at least one adhesion promoting coating disposed between each of the core and the outer layer; the core comprising a rubber composition comprising at least one zinc-containing and/or magnesium-containing component; the outer layer comprising at least one ionomer; and the adhesion promoting coating comprising a waterborne dispersion comprised of at least one ethylene acid copolymer having an acid content of at least 15% by weight wherein the copolymer is at least partially neutralized with one or more neutralizing agent; wherein at least one neutralizing agent is selected from ammonia compounds and/or amine compounds. In a specific embodiment, the at least one neutralizing agent comprises i) mono and/or divalent metal compounds and ii) ammonia compounds and/or amine compounds.
Abstract:
A golf ball includes a plurality of layers. The layers include at least one core layer, at least one intermediate or cover layer, and at least one coating layer. At least one of these layers is formed from a composition having both a plurality of non-functionalized inorganic aluminosilicate ceramic microspheres, and a plurality of functionalized inorganic aluminosilicate ceramic microspheres dispersed throughout.

Abstract:
A golf club head having a damping treatment, such as a viscoelastic polymer, is disclosed. The viscoelastic polymer may be in contact with the rear surface of a striking face of the golf club head. The viscoelastic polymer may have a tangent of delta peak temperature between −70 degrees Celsius and −20 degrees Celsius at a 1 Hz frequency. An elastic modulus (E), in megapascals (MPa), of the viscoelastic polymer has a relationship to a striking face thickness (t), in millimeters (mm), defined by Ê≤−14{circumflex over (t)}+305. The elastic modulus (E), in megapascals (MPa), of the viscoelastic polymer has a relationship to an effective stiffness (S) of the striking face, in gigapascals per meter (GPa/m), defined by Ê≤−1.16Ŝ+258.33. The viscoelastic polymer may cover a portion of the rear surface of the striking face or may substantially fill a cavity of the golf club head.
Abstract:
Golf ball comprising one or more layers and/or indicia formed from a fluorescent composition comprising: a base polymer; and a colorant; wherein the colorant is a small-molecule ionic isolation lattice formed from one or more fluorescent dye and one or more cyanostar macrocycles. The one or more fluorescent dyes may include at least one dye selected from xanthenes, oxazines, styryls, cyanines, trianguleniums, or mixtures thereof. The colorant may be a dispersion of the small-molecule ionic isolation lattice in a carrier medium or a powder. In particular embodiments, at least one of the one or more layers is a cover layer and/or a coating layer.
Abstract:
Golf balls of the invention include at least one core layer comprised or consisting of a homogenous rubber-based core composition with a plurality of functionalized inorganic aluminosilicate ceramic microspheres dispersed throughout without agglomerating to create a relatively higher cross-link density of the core layer material. In golf balls of the invention, cross-link density gradients may be created between core layers by pre-electing the presence/absence, amount, type, and degree of functionalization of the plurality of functionalized inorganic aluminosilicate ceramic microspheres in two given core layers to target important properties such as resilience/CoR and desired playing characteristics such as distance.
Abstract:
Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. In one embodiment, the outer cover layer is formed from a composition comprising a thermoplastic polyurethane and epoxy compound. Mixtures of multi-functional amines and imines, and multi-functional isocyanates, and epoxy curing agents; and solvent, can be applied to the outer cover. The resulting coating may contain polyurethanes, polyureas, and hybrids, copolymers, and blends thereof. The cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. The coating methods have many benefits and the finished balls have good physical properties.
