Abstract
A method of forming golf balls with at least a portion formed from polyurethane and polyurea compositions employing a curative blend that includes a pigment, a curing agent, and a compatible freezing point depressing agent so that the curative blend has a lower freezing point than the curing agent by itself and the blend does not lose pigment dispersion upon solidification and subsequent thawing.
