    摘要： A golf ball is provided including a core (12), a cover (14) encasing the core and a coating (16) that comprises a resin applied to the outer surface of the cover. Particles (22) comprising a high density material are included in the coating such that the coating has a density at least twice that of the core's density or contributes at least 0.60% of the golf ball's total moment of inertia, and the coating has a micro surface roughness at least 1.75 times larger than the roughness of a comparative ball. A method of making a golf ball is also provided, including providing a spherical core, encasing the core with a cover, applying a resin to the outer surface of the cover, and adding a plurality of particles comprising a high density material to form a coating material that has a second density at least two times the first density.

    摘要： A thread wound golf ball having improved characteristics of moment of inertia, spin, and total flight distance, comprising a center, a thread winding layer disposed over the center forming a core, and a cover disposed over the core. The improved characteristics are achieved by shifting the weight of the golf ball from the center towards the periphery by use of heavy thread. This could be achieved by adding a high specific gravity filler material, such as tungsten, to the conventional thread compound and/or using polymer materials in the thread that are inherently heavier. By using a high specific gravity filler material, other desirable characteristics inherent in a wound ball such as resilience, controllability and feel, are not affected.

    摘要： In a multi-piece solid golf ball comprising a solid core and a cover of two inner and outer layers enclosing the solid core, the solid core has a deflection of at least 1.1 mm under an applied load of 294 N (30 kgf) and a surface and a center, the surface-center hardness difference given as a JIS-C hardness at the core surface minus a JIS-C hardness at the core center is greater than 15 units, the cover inner layer is formed of a resin composition comprising as essential components, (a) an olefin-unsaturated carboxylic acid random copolymer, an olefin-unsaturated carboxylic acid-unsaturated carboxylate random copolymer, a metal ion neutralized product of each copolymer, or a mixture of each copolymer and the neutralized product, (b) a fatty acid having a molecular weight of at least 280 or derivative thereof, and (c) a basic inorganic metal compound capable of neutralizing acid groups in components (a) and (b), the Shore D hardness of the cover inner layer, the Shore D hardness of the cover outer layer, and the hardness relationship between the cover inner layer and the cover outer layer are adjusted, and the sum of dimple trajectory volumes each obtained by multiplying the volume of a dimple by the square root of a dimple diameter is optimized.
