Abstract
A coating material is blended preferably in an amount of 60 to 90% by mass relative to paint film forming components thereby to form a curable solvent-based topcoating material. The coating material includes an oleophilic polyrotaxane which includes a cyclic molecule, a linear molecule including the cyclic molecule with piercing through the cyclic molecule, and blocking groups which are placed at both end terminals of the linear molecule to prevent the cyclic molecule from leaving from the linear molecule, at least one of the above-mentioned liner molecule and the cyclic molecule having hydrophobic modification group.
