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 formed from a curing type paint composition including:
• a base material containing a polyrotaxane and at least one polyol selected from the group consisting of a polyether polyol, a polyester polyol, a polycaprolactone polyol, a polycarbonate polyol, and an acrylic polyol, and
• a curing agent containing a polyisocyanate;
• and
• wherein
• the polyrotaxane comprises a cyclodextrin, and a linear molecule included in the cyclodextrin cyclic structure in a manner of piercing through the cyclic structure of the cyclodextrin, the linear molecule having blocking groups located at both ends of the linear molecule to prevent disassociation of the cyclodextrin, and at least a portion of the cyclodextrin hydroxyl groups being modified with a caprolactone chain expressed by —(CO(CH2)5O)nH via a —O—C3H6—O— group, wherein n represents the degree of polymerization and is a natural number of 3 to 40, and
• a resin component of the base material contains the polyol in an amount of 5 mass % or more and 90 mass % or less.
