Abstract
In a golf ball including a core and a cover of at least one layer, the cover layer is formed of a heated mixture of an ionomer resin and a metal salt such as magnesium stearate. The heated mixture exhibits such a crystal melting behavior that when measured by DSC, the difference between first and second peak temperature is up to 30° C. The ball is improved in resilience.
