摘要

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.;COPYRIGHT: (C)1996,JPO
