Abstract
The present invention is directed to a golf ball having at least one layer formed from a rubber composition comprising a base rubber, a free radical initiator, and a quinhydrone. The free radical initiator is generally present in the rubber composition in an amount of at least 0.05 parts by weight per 100 parts of the base rubber. The quinhydrone is generally present in the rubber composition in an amount of at least 0.05 parts by weight per 100 parts of the base rubber. The rubber composition may be present in any one or more of a core layer, a cover layer, or an intermediate layer.
