Abstract
The multilayer coating film formation method for forming a multilayer coating film on a substrate comprises the steps of: applying an undercoat paint composition (X) comprising an antioxidant (a1) to a substrate to form at least one layer of an uncured first coating film; applying a topcoat paint composition (Y) containing a carboxy-containing polymer (b1) and an epoxy-containing acrylic resin (b2) to the first coating film to form an uncured second coating film; and simultaneously heating the uncured first coating film and the uncured second coating film to cure the films.
