摘要： To provide a golf ball that can prevent considerable decrease in carry distance of a driver shot when it rains and also can more reliably prevent adhesion of dirt, etc. to the surface of the golf ball. The golf ball of the present invention includes a core, a cover that is provided on an outer side of the core and is provided with dimples, and an outermost layer that is formed on an outer side of the cover and made of a material having a contact angle of 90° or more, a dynamic contact angle of 85° or less and an adhesive force of 130 μN or less. The material for forming the outermost layer includes a urethane coating material with a water repellent additive.

摘要： In a golf ball having a core, a cover of at least one layer and a paint film layer formed on a surface of the cover, the paint film layer has an elastic work recovery of at least 60%, the cover layer in contact with the paint film layer has a material hardness on the Shore D scale of at least 55 and, letting M be the elastic work recovery (%) of the paint film layer and N be the material hardness (Shore D hardness) of the cover layer, M−N>0. The ball surface is scratch-resistant and has an excellent durability, and the ball has a reduced spin rate on shots with a driver or a long iron, resulting in an increased carry.

摘要： The invention provides a solid golf ball having a core and a cover. The core is formed of a rubber composition containing a base rubber, a co-crosslinking agent, a crosslinking initiator and a metal oxide. The co-crosslinking agent is methacrylic acid, and the rubber composition includes a specific waste material in the form of a powder. The core deflection and the cover material are optimized. Utilizing a waste material in a solid golf ball conserves resources and thus is beneficial to the global environment. Even during prolonged use, the golf ball maintains its basic performance attributes (feel, flight, durability) at a high level.

摘要： A multi-piece solid golf ball having a core, at least one intermediate layer encasing the core and at least one outer layer encasing the intermediate layer is characterized in that the intermediate layer is formed of a resin composition containing a specific acid-containing polymer or ionomer resin, and the outer layer is formed of primarily a polyurethane or a polyurea. The ball also has, between the intermediate layer and the outer layer, a bonding layer made of a polycarbonate and/or polyether-type aqueous polyurethane dispersion composition which includes a specific aqueous polycarbodiimide.

摘要： A golf ball paint composition includes primarily a urethane paint made of a polyol and a polyisocyanate. The polyol is an acrylic polyol, and the composition has an elastic work recovery of at least 70%. The paint composition has a high self-repairing ability and is of high quality as a golf ball paint. Golf balls coated with this composition are able to maintain a good durability, in addition to which they have an excellent abrasion resistance and an excellent ball appearance.
