A golf ball according to an embodiment of the present disclosure is covered with an injection-molded crosslinked polyurethane. The golf ball may have excellent scuff resistance and light resistance of a cover as well as excellent driving distance and spin by using a cover composition containing crosslinked polyurethane obtained by adding a crosslinking agent to thermoplastic polyurethane (TPU). A polyurethane cover composition according to an embodiment can make it possible to prepare a crosslinked polyurethane cover by injection molding without the burden of facility investment cost.
