PURPOSE: To provide the titled coating compsn. contg. aqueous dispersion of a cationic or amphoteric vinyl copolymer and a pigment but no emulsifier, etc., which is easy to handle and has excellent dispersion stability.
CONSTITUTION: An aqueous dispersion of vinyl copolymer is prepd. by copolymerizing 2W35pts.wt. α,β-ethylenically unsatd. monomer having a tertiary amino group (e.g. dimethylaminoethyl methacrylate) with 98W65pts.wt. another α,β- ethylenically unsatd. monomer (e.g., methyl acrylate) in a water-soluble solvent (e.g. propanol or butyl cellosolve) in which 1W20wt% polyalkylene glycol having an MW of 600W2,000 (e.g. polyethylene glycol) has been dissolved, and water is added to it for dispersion. The water-based coating compsn. is prepd. by mixing about 90W10pts.wt. (on a solid base resultant resin dispersion with 10W90pts.wt. pigment.
