Abstract
To provide a coating material for a room temperature curable solvent-borne overcoating material having chipping resistance and not allowing occurrence of cracks, and a room temperature curable solvent-borne overcoating material using the same, the room temperature curable solvent-borne overcoating material being excellent in abrasion resistance and in performance such as weather resistance, contamination resistance and adhesion. A coating material is formed of a lipophilic polyrotaxane including a cyclic molecule, a linear molecule piercing through the cyclic molecule to include it, and blocking groups disposed at both end terminals of the linear molecule to prevent departure of the cyclic molecule. In the lipophilic polyrotaxane, at least one of the linear molecule and the cyclic molecule has a hydrophobic modification group. A room temperature curable solvent-borne overcoating material is formed to contain the coating material preferably within a range of from 60 to 100% by mass relative to a film-forming component.
