COATING MATERIAL FOR PROTECTING AUTOMOBILE COATING FILM AND PROTECTION OF THE SAME

PURPOSE: To obtain the subject coating material containing a specific copolymer, a specific film-forming auxiliary and a specific coloring pigment as main components, maintaining an excellent coating film appearance, and excellent in coatability, removing workability, environmental compatibility and protectability from UV light, chemical changes and physical impacts. CONSTITUTION: This coating material contains (A) 35-55 pts.wt. of a copolymer produced by copolymerizing an organic silicon-containing monomer having more than one polymerizable unsaturated groups and one or more siloxane bonds in the molecule (e.g. vinyldimethylpolysiloxane, γ- methacryloxypropyldimethylpolysiloxane) with a polymerizable monomer capable of being copolymerized with the same [e.g. (meth)acrylic acid (methyl ester)], (B) 1-5 pts.wt. of a film-forming auxiliary such as the methyl ether or n-butyl ether of a propylene glycol compound, and (C) 3-10 pts.wt. of a coloring pigment such as titanium dioxide, titanium yellow or carbon black as main components.
