摘要: A golf ball 2 includes a core 4, a mid layer 6 positioned outside the core 4, a reinforcing layer 8 positioned outside the mid layer 6, and a cover 10 positioned outside the reinforcing layer 8. The difference between: a JIS-C hardness H(5.0) and a JIS-C hardness Ho at the central point is 6.0 or greater. The difference between: a JIS-C hardness H(12.5) and the hardness H(5.0) is 4.0 or less. The difference between a JIS-C hardness Hs at the surface of the core 4 and the hardness H(12.5) is 10.0 or greater. The difference between the hardness Hs and the hardness Ho is 22.0 or greater. In the golf ball 2, there is no zone in which a hardness decreases from the central point toward the surface. A hardness H2 of the mid layer 6 is greater than a hardness H3 of the cover 10.

摘要: A golf ball 2 includes a core 4, amid layer 6 positioned outside the core 4, a reinforcing layer 8 positioned outside the mid layer 6, and a cover 10 positioned outside the reinforcing layer 8. The core 4 is obtained by a rubber composition being crosslinked. The rubber composition includes a base rubber, a co-crosslinking agent, a crosslinking initiator, and a carboxylate. The co-crosslinking agent is: (1) an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms; and/or (2) a metal salt of an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms. The amount of the carboxylate is equal to or greater than 1.0 parts by weight but less than 40 parts by weight per 100 parts by weight of the base rubber. A hardness of the mid layer 6 is greater than a hardness of the cover 10.

摘要: A golf ball includes a core, a cover covering the core, and a clear layer covering the cover. The cover has dimples and a land. An xy coordinate of a hue of an outermost layer in the core excluding a colorless and transparent layer is included in any one of eight zones I to VIII. An xy coordinate of a hue of the cover is included in any one of the eight zones I to VIII which is different from and is not adjacent to the zone in which the xy coordinate of the hue of the outermost layer is included. A ratio (T1/T2) of a thickness T1 of the cover immediately below a deepest portion of each dimple and a thickness T2 of the cover immediately below the land is equal to or greater than 0.50 but equal to or less than 0.80.
