AQUEOUS COATING COMPOSITIONS FOR FORMING ANTI-GRAIN-PUFFING COATINGS ON WOOD SUBSTRATE, AQUEOUS PAINTS AND ARTICLES

摘要

The present invention relates to aqueous coating compositions for forming an anti- grain-puffing coating, aqueous primers comprising the aqueous coating composition, and articles comprising the anti-grain-puffing coating. In particular, the aqueous coating composition comprises: (a) an aqueous dispersion of polymeric particles, wherein the polymer particles comprise polymer having an anionic hydrophilic group on its molecule chain, and the aqueous dispersion of polymeric particles has a pH of less than 7.0; and (b) an aqueous dispersion of nano-silica.
