AQUEOUS AMINO RESIN DISPERSIONS AND THERMOSETTING WATERBASEDPAINT COMPOSITIONS

摘要

An aqueous amino resin dispersion excelling in storage stability and mechanical stability which is formed by dispersing hydrophobic amino resin in aqueous medium, using a polyester resin having specific hydroxyl value, acid value and number-average molecular weight as a dispersion stabilizer, said polyester resin being prepared by reacting polyhydric alcohol, polycarboxylic acid and/or polycarboxylic anhydride and monoepoxide compound having a long chain hydrocarbon group thermosetting, water-based paint compositions comprising the aqueous amino resin dispersion and multi-layered coating film-forming methods using the water-based paint compositions are provided.
