An object of the present invention is to provide a golf ball having a polyurethane cover, which is excellent in flight performance and weather discoloration resistance without lowering the productivity of the polyurethane cover. The polyurethane cover has an isocyanate group-terminated urethane prepolymer having at least one diisocyanate selected from the group consisting of 4,4'-dicyclohexylmethane diisocyanate, isophorone diisocyanate, and cyclohexane diisocyanate as an isocyanate component. It is characterized by being obtained by curing a polyurethane cover composition containing a phenylenediamine derivative represented by the following general formula (1). Embedded image (In the formula, R 1 to R 4 may be the same or different, and each is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms.) |
