Abstract
An object of the present disclosure is to provide a golf ball that has a low maximum flying height on driver shots by an average golfer. The present disclosure provides a golf ball comprising a spherical core, an intermediate layer and an outermost cover, wherein the spherical core is formed from a rubber composition containing a rubber component, a co-crosslinking agent, and a crosslinking initiator, the co-crosslinking agent contains methacrylic acid and/or a metal salt thereof, a total lower volume Vi (mm3) of the plurality of dimples is 365 mm3 or more, and an occupation ratio of the dimples is 75% or more.
Claims15
A golf ball comprising a spherical core, at least one intermediate layer positioned outside the spherical core, and an outermost cover positioned outside the intermediate layer and having a plurality of dimples formed thereon, wherein
- the spherical core is formed from a rubber composition containing a rubber component, a co-crosslinking agent, and a crosslinking initiator,
- the co-crosslinking agent contains methacrylic acid and/or a metal salt thereof,
- a total lower volume Vi (mm3) of the plurality of dimples is 365 mm3 or more, and
- an occupation ratio of the dimples defined by the following formula is 75% or more;
- Occupation ratio (%) of dimples=100×total area of all dimples/surface area of a virtual sphere that is assumed to have no dimples on golf ball surface.
