Colored golf ball and method of making same
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.
GOLF BALL
An object of the present invention is to provide a golf ball showing an increased spin rate on approach shots under a wet condition while maintaining a spin rate on approach shots under a dry condition. The present invention provides a golf ball comprising a golf ball body and a paint film formed on a surface of the golf ball body, wherein the paint film has a multi-layered construction composed of two or more layers, and a difference (M.sub.inM.sub.out) between a 10% elastic modulus (M.sub.in) of an innermost layer of the paint film and a 10% elastic modulus (M.sub.out) of an outermost layer of the paint film is 25 kgf/cm.sup.2 or more.

PLAY BALL WITH FOAM FILLING
A play ball has a rubber shell filled with resilient foam having an entire outer peripheral surface thereof intimately attached by heat fusion and adhesive to an entire interior surface of the shell. Such attachment enables the foam to provide additional resiliency by foam tension, as well as by foam compression, thereby significantly extending the effective bounce life of the ball. A seamed dog chew toy has essentially similar construction such that the increased retention force provided by the intimate attachment of the foam to the shell resists the chewing force of the dog popping a seam improving durability.

Training ball
Training balls are presented including: a solid sphere defining a first hemisphere having a first surface and a second hemisphere having a second surface; a tactile feature positioned along the first surface and substantially centered with the first hemisphere, where the tactile feature includes: a center portion having a closed geometric shape; and a continuous grooved border encompassing the center portion; a first grooved feature positioned along the second surface, where the first grooved feature includes a first body segment; a second grooved feature positioned along the second surface, where the second grooved feature includes a second body segment, where the first body segment and the second body segment are substantially parallel, and where the first grooved feature and the second grooved feature are substantially centered with and solely upon the second hemisphere along the second surface.
Wind tolerant ball
The ball is a thin-walled hollow sphere that includes an array of apertures with dimples in a pattern that are concentric to the aperture array. Dimples are provided on the exterior surface of the ball between the apertures with the pattern and dimensions of the dimples varying based on proximity to the apertures. Internal protuberances are provided on the interior surface of the hollow ball such that the interior surface also manages aerodynamic airflow through the ball. Channels are also provided around each of the apertures within the ball which may intersect proximate dimples or be spaced therefrom. The ball also includes apertures having converging and diverging sidewalls that form a venturi shape to increase inflow air into the apertures and outflow air out of the apertures. Finally, the ball also maintains a weight:diameter ratio within a fixed range.

Golf ball with soft coating and hard cover
A golf ball has a cover with a Shore D hardness of at least about 59 and a coating on the cover that has at least one of (a) a pencil hardness of 2 B or less, (b) a Sward hardness of about 40 or less, or (c) a Hit (Young's Modulus)<20 N/mm.sup.2 and h.sub.max>0.55 micrometer.
Dimple patterns for golf balls
The present invention provides a golf ball wherein each hemisphere has a dimple pattern based on a pyramid having dissimilar sides. The resulting overall dimple pattern is not based on preexisting polyhedral, and is not attainable using conventional dimple packing methods.
