Golf ball

A golf ball comprising a golf ball body and a paint film formed on a surface of the golf ball body,

• wherein the paint film is composed of at least one layer, and an outermost paint film layer located at the outermost layer of the golf ball contains, as a base resin, a polyurethane obtained by a reaction between (A) a polyisocyanate composition and (B) a polyol composition,
• (A) the polyisocyanate composition contains an adduct-modified product of hexamethylene diisocyanate and an isocyanurate-modified product of hexamethylene diisocyanate as a polyisocyanate component, and
• the adduct-modified product of hexamethylene diisocyanate is a product obtained by a reaction between hexamethylene diisocyanate and a polyhydric alcohol,
• an amount of the adduct-modified product of hexamethylene diisocyanate in the polyisocyanate component is 50 mass % or more,
• a total amount of the adduct-modified product of hexamethylene diisocyanate and the isocyanurate-modified product of hexamethylene diisocyanate in the polyisocyanate component ranges from 70 mass % to 100 mass %, and
• the outermost paint film layer has a dynamic friction coefficient of from 0.75 to 1.5 measured with a dynamic friction tester under the following conditions:
• <measurement conditions>
• moving speed:
• 2 mm/s
• load:
• 1.96 N
• measuring item:
• dynamic friction average value for a moving distance of from 2 mm to 10 mm.
