Water-dispersible resin composition, water-dispersible coating compositon and coating method using the coating composition. |
摘要 |
<p>Disclosed are (1) a water-dispersible resin composition prepared by a process comprising; (I) reacting a silane monomer (A) having hydrolytic functional group and/or silanol group and polymerizable unsaturated bond with a vinyl monomer (B) in an aqueous medium to obtain a three-dimensionally crosslinked particulate polymer, (II) reacting the particulate polymer with the silane monomer (A) and/or an allyl acrylate or allyl methacrylate (C), and (III) copolymerizing the resulting reaction product with a vinyl monomer component comprising a carboxyl-containing vinyl monomer (D), followed by neutralizing the carboxyl group; (2) a water-dispersible coating composition comprising a crosslinking agent and the water-dispersible resin composition prepared using a hydroxyl-containing vinyl monomer and another vinyl monomer as the vinyl monomer (B) in the step (I), and (3) a coating method characterized by using as a base coat composition a water-dispersible coating composition comprising the foregoing water-dispersible coating composition and a coloring pigment and/or metallic pigment in the two-coat method.</p> |
