    摘要: A golf ball of the present invention includes: a core located in the center of the golf ball; a cover surrounding the outside of the core and having plural dimples on the surface thereof; and a paint layer surrounding the outside of the cover. The paint layer is formed of a material having rubber elasticity. When the golf ball has a μ hardness and the paint layer has a JIS-C hardness, a ratio Sp of the JIS-C hardness of the paint layer with respect to the μ hardness of the golf ball is at most approximately 15. When the cover has a Shore D hardness, a ratio Sc of the Shore D hardness of the cover with respect to the μ hardness of the golf ball may be at most approximately 25.

    摘要: A golf ball of the present invention includes: a core located in the center of the golf ball; a cover surrounding the outside of the core and having plural dimples on the surface thereof; a paint layer surrounding the outside of the cover; and a top coat further surrounding the outside of the paint layer. The paint layer is formed of a material having rubber elasticity. The top coat may have a thickness of at most approximately 60 μm. A material for forming the paint layer has a first loss tangent, a material for forming the cover has a second loss tangent, and a difference Td between the first loss tangent and the second loss tangent may be at least approximately 0.05.

    摘要: A golf ball includes, as a constituent element thereof, a molded and crosslinked product obtained from a rubber composition containing (A) a base rubber which includes a polybutadiene having a cis-1,4 bond content of at least 60 wt %, (B) an unsaturated carboxylic acid and/or a metal salt thereof, (C) an organosulfur compound, (D) one or more organic peroxide selected from the group consisting of peroxyketals and/or dialkyl peroxides, and (E) one or more organic peroxide selected from the group consisting of hydroperoxides. In the golf ball, the value obtained by subtracting a center hardness of the molded and crosslinked product from a surface hardness thereof, expressed as the JIS-C hardness, is at least 20. The golf ball has a reduced spin rate on shots with a driver and therefore is able to follow a reliable trajectory that does not tend to dip or to rise in a high arc, enabling an increased distance to be achieved.
