Nanocellulose-containing aqueous coating composition for automotive exterior

Abstract

An aqueous coating composition for an automotive exterior, containing resin particles (A), a crosslinking agent (B), a pigment (C), and a nanocellulose (D), wherein a content of the nanocellulose (D) is 0.5 to 2.0 parts by mass in terms of solid content with respect to 100 parts by mass of a resin solid content in the coating, a solid content concentration of the coating composition is in a range from 45 to 65 mass %, and a viscosity is in a range from 350 to 1200 mPa·s. Also, an automobile coated with the aqueous coating composition, a method of forming a coating film using the aqueous coating composition, and a method of forming a multilayer coating film comprising applying the aqueous coating composition on an object, applying an aqueous second colored coating composition thereon, then applying a clearcoat coating composition thereon, and simultaneously heat-curing the compositions.
