Abstract: The present invention provides a coloring base coating material capable of forming a base coating film superior in design property (e.g., unevenness of a luster pigment), adhesion, and water resistance while satisfying environmental considerations such as shortening of drying time, and also provides a coated article obtained from the coloring base coating material. The present invention provides a coating method including: a step of applying a coloring base coating material to a molded article for an automobile part made of a plastic material to form an uncured first coating film, a step of applying a two-pack clear coating material to the uncured first coating film to form an uncured second coating film, and a step of baking and curing the uncured first coating film and the uncured second coating film to form a multilayer coating film, wherein the coloring base coating material is specified.

Abstract: The present invention provides a base coating composition capable of forming a base coating film superior in design property (e.g., unevenness of a luster pigment), adhesion, and water resistance while satisfying environmental considerations such as shortening of drying time, and also provides a coated article obtained from the base coating composition. The present invention provides a base coating composition comprising a pigment (A), a hydroxy group-containing acrylic resin (B), a blocked isocyanate compound (C), crosslinked polymer fine particles (D) insoluble and stably dispersed in a solution of the hydroxy group-containing acrylic resin (B), and an acrylic resin (E) having a weight average molecular weight different from that of the hydroxy group-containing acrylic resin (B), wherein the specific hydroxy group-containing acrylic resin (B) is used and a viscosity recovery rate is adjusted. The present invention also provides a coated article formed using a base coating composition.
