Abstract:
Structure of a golf ball and a method of manufacturing same. The object of the present invention is to provide golf balls characterized by the same or similar impact feeling and click character that are offered by golf balls covered with balata compounds, while simultaneously maintaining the excellent properties of golf balls covered with ionomer resin, as has recently been proposed. In accordance with this invention, a golf ball is provided with a core (2) of wound rubber yarn on the surface of which latex (4) is impregnated. Said latex contains monoolefine and, as a solids content, 30 to 60% by weight of ionomer resin with ionic cross-linking, containing at least one selected from the group consisting of unsaturated mono- or di-carboxylic acid or esters thereof, of 3 to 8 carbon atoms. The impregnation of the latex (4) improves the bonding strength between the surface of the core (2) and the spherical inner surface of the golf ball shell.
