摘要： A golf ball having a cover thickness of 3.0 to 5.0 mm is produced by a process which includes providing a core; covering the core with a cover composition to form a first cover layer having a thickness of 30 to 70% of a total cover thickness; and further covering the first cover layer with the same cover composition to form a second cover layer having a thickness sufficient to form the total cover thickness.

摘要： A golf ball has plural dimples on its surface. Each dimple has a dimple deepest portion not corresponding to a center of the dimple as viewed in radial direction toward a center of the golf ball. A cross acute angle, between, a straight line which goes through the dimple deepest portion and the center of the dimple, and a great circle zone which goes through poles and the center of the dimple, is arranged to be -85.degree. to 85.degree.. The dimple deepest portion is positioned nearer to a seam than the center of the dimple and the depth of the dimple diminishes gradually and monotonically from the deepest portion to a radially outer portion.

摘要： A solid golf ball comprising a core and a cover wherein the core has a diameter of not more than 36.7 mm and a hardness (JIS-C hardness) in a range from 65.5 to 72 from a center to an outer surface thereof. The core is formed from a vulcanized molded material of a rubber composition comprising a base rubber, a metal salt of an unsaturated carboxylic acid, an organic peroxide, an organosulfur compound and/or metal-containing organosulfur compound and a filler. A difference between the hardness (JIS-C hardness) at the center of the core and that at any part from the center to the outer surface of the core is not greater than 5. The cover has a specific gravity of less than 1.2, a thickness of 3 to 5 mm and a hardness (Shore-D scale hardness) of 60 to 70.
