Abstract
A golf ball having a center core, one or more envelope layer encasing the center core and one or more cover layer is provided wherein at least one envelope layer is formed of a rubber composition that includes (a) a diene rubber, (b) a tetrazine compound of a specific formula or a metal salt thereof, (c) an α,β-unsaturated carboxylic acid metal salt and (d) an organic peroxide. A method for manufacturing the golf ball is also provided. The golf ball has a high rebound and durability. The manufacturing method, by eliminating the need to furnish equipment for a bonding step, lowers production costs and is industrially advantageous.
