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.

A golf ball dimple pattern based on a square dipyramid, i.e., two square pyramids connected base-to-base, is disclosed. The dimples are arranged within four substantially identical triangular sections on each of two substantially identical hemispheres of the ball.

A golf ball including an outer surface having dimples located on the outer surface, at least one core, at least one mantle layer, at least one cover layer, and a plurality of images located on the outer surface, the images being provided with at least two contrasting colors, wherein the plurality of images each have a Major Peak Ratio of between 0.18 and 1, a Major Valley Ratio of between 0.18 and 1, a slope value of between −5 and 5, and an intercept value between 5 and 80.

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.

A method of dispersing ashes of a subject comprising cremating the subject's body to form ashes, and introducing a sample of the ashes into a spherical golf ball having a frangible outer surface and at least one inner cavity.

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 provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.

A golf ball with a cover layer composed of a blend of non- or partially neutralized copolymeric or terpolymeric ionomer(s), hydroxyl-functionalized styrenic block copolymer and silane coupling agent (SCA). The amount of SCA is preferably between 0.01 and 2.0 weight percent based on the total weight of the polymer composition. The cover layer preferably has a Shore A hardness less than 90.

A golf ball has a core, an inner cover, an outer cover, and dimples. The golf ball satisfies the following mathematical formulas.
Sa=4500+10(A−0.5B−2Cs)≥4000
0.04Sa+160−20≤D≤0.04Sa+160+20 A: a compression (Atti) of the golfball B: a hardness difference (Shore C) between a surface and a center of the core Cs: (Hi×Ti+2Ho×To)/(Ti+2To) D: a total volume (mm.sup.3) of the dimples Hi: a hardness (Shore D) of the inner cover Ho: a hardness (Shore D) of the outer cover Ti: a thickness (mm) of the inner cover To: a thickness (mm) of the outer cover

In a golf ball having a core and a cover, the cover is formed primarily of polyurethane, the ball has a diameter of at least 42.8 mm and a weight of not more than 44.9 g and, in an impact test carried out by hitting the ball with a driver at a head speed of 40 m/s, the sum t1+t2 of the time t1 required from initial contact by the driver with the ball for deformation of the ball to reach a maximum and the time t2 required from the state of maximum ball deformation for the ball and driver to separate is not more than 660 μsec. This golf ball makes it possible for golfers who have a high head speed and ordinary golfers who do not to compete without relying excessively on superiority in terms of distance.
