Golf ball having a polyurethane cover

   
   

A solid golf ball having a polyurethane cover and containing satisfactory formability and ball properties. The golf ball provides good shot feel, controllability, and resilience by adjusting the hardness and the thickness of the polyurethane cover, and the hardness of the entire golf bal. The formability of the polyurethane cover is improved by controlling the amount of residual isocyanate monomer contained in the isocyanate group-terminated urethane prepolymer.
