Abstract
A core is enveloped by a cover with trans 1,4-polyisoprene as the main component, including a super accelerator formed of dithiocarbamate and/or xanthate, and vulcanized at a temperature lower than the melting point of trans 1,4-polyisoprene to provide a golf ball having high impact resilience and spinning performance. Also, a core is enveloped by an inner layer cover having trans 1,4-polyisoprene as the main component, including a super accelerator formed of dithiocarbamate and/or xanthate, and the inner layer cover is surrounded by an outer layer cover with trans 1,4-polyisoprene as the main component, including a super accelerator of an amount larger than that in the inner layer cover to provide a golf ball having high impact resilience and spinning performance, and whose cover material is sufficiently anchored.
