    Abstract: Hydrophilic coating compositions and methods to make and use the compositions are disclosed. The coatings include one or more amphiphilic cyclodextrins, with one or more hydrophilic groups in place of primary hydroxyl groups, and one or more hydrophobic groups in place of secondary hydroxyl groups. The hydrophobic surface of the cyclodextrin faces the binder particles, while the hydrophilic surface is exposed to the exterior, thus providing a hydrophilic and self-cleaning property to the coating.

    Abstract: An object of the present invention is to provide a golf ball showing increased controllability on approach shots for less than 40 yards and showing excellent shot feeling. In the inventive golf ball, the paint film is formed from a curing type paint composition including: a base material containing a polyrotaxane, and a curing agent containing a polyisocyanate, and wherein the polyrotaxane has a cyclodextrin, a linear molecule included in a cyclic structure of the cyclodextrin in a manner of piercing through the cyclic structure of the cyclodextrin, and a blocking group located at both ends of the linear molecule to prevent disassociation of the cyclodextrin, and at least a part of hydroxyl groups of the cyclodextrin is modified with a caprolactone chain via —O—C3H6—O— group.
