Abstract
The present invention is directed to providing an aqueous dispersion of acrylic urethane composite resin (AB) particles that, when used as a constituent component of an aqueous coating composition, provides the aqueous coating composition with excellent storage stability, the aqueous coating composition being capable of forming a coating film with excellent abrasion resistance, chipping resistance, and glass adhesiveness even when the aqueous coating composition is cured at a relatively low temperature. The aqueous dispersion of acrylic urethane composite resin (AB) particles including a urethane resin portion (A) produced from constituent components including a compound (a1) having a secondary amino group and an alkoxysilyl group and an isocyanate group-containing urethane prepolymer (a2), and an acrylic resin portion (B) produced from constituent components including a compound (b) having a polymerizable unsaturated group and having no hydroxyl group or one hydroxyl group.
