Abstract: A golf ball includes a ‘dual core’ formed from an inner core layer and an outer core layer. The inner core has an outer surface and a center and is typically formed from a substantially-homogenous rubber composition such that the center of the core has a hardness of about 72 Shore C to about 78 Shore C and a trans content of about 5% to 9%, and the outer surface of the inner core has a trans content of about 5% to 9%. The trans content of the outer surface and the center of the inner core are preferably within 2% of each other and, more preferably are substantially the same to define a zero trans gradient along a radius of the inner core.

Abstract: Golf ball 2 has spherical main body 4, mark layer 6 and paint layer 8. The main body 4 has spherical core 10, and cover 12 provided to cover this core 10. The cover 12 does not include titanium oxide. The cover 12 includes a fluorescent colorant. The main body 4 has a chroma saturation of equal to or greater than 25. The paint layer 8 is constituted with a resin composition. This resin composition includes composite particles. The composite particle has a nucleus, and a coat layer provided to coat this nucleus. The nucleus is constituted with mica, while the coat layer is constituted with titanium oxide. The amount of the composite particles is 2 parts by weight or greater and 30 parts by weight or less per 100 parts by weight of the base resin of the paint layer 8.

Abstract: The present invention provides a multi-piece solid golf ball, which is superior in flight distance, spin performance, shot feel and putting sound. The present invention relates to a multi-piece solid golf ball comprising a core consisting of a center, an intermediate layer formed on the center and an outer layer formed on the intermediate layer, and a cover covering the core, wherein the center has a diameter of 10 to 20 mm and a central point hardness in JIS-A hardness of 30 to 85, the intermediate layer has a surface hardness in Shore D hardness of 30 to 55, the outer layer has a hardness in Shore D hardness of 65 to 85 and comprises thermoplastic resin as a main component, and the cover has a Shore D hardness of 35 to 55 and a thickness of 0.3 to 1.5 mm.

Abstract: Disclosed herein is a multi-layer golf ball having a soft outer cover. The golf ball has a core, one or more mantle or inner cover layers with a Shore D hardness of 60 or more, and an outer cover with a Shore D hardness of 53 or less. In a particularly preferred form of the invention, the inner and/or outer cover layers comprise a reaction injection molded polyurethane. The golf ball of the invention has exceptionally soft feel and high spin rates on short shots of 80 yards or less and, particularly, 40 yards or less, while maintaining good distance and average spin on full shots.

Abstract: Disclosed herein is a multi-layer golf ball having a soft outer cover. The golf ball has an inner cover layer with a Shore D hardness of 60 or more, and an outer cover with a Shore D hardness of 55 or less, and more preferably 50 or less. In a particularly preferred form of the invention, the outer cover comprises at least 75% of a soft copolymer formed from a polyolefin, an unsaturated carboxylic acid, and a monomer of the acrylate ester class. The golf ball of the invention has exceptionally soft feel and high spin rates on short shots of 80 yards or less and, particularly, 40 yards or less, while maintaining good distance and average spin on full shots.
