Inhibition by oxygen of the peroxide-initiated cure of a composition based on (meth)acrylates or other compounds containing free radical-polymerizable functional groups is mitigated by inclusion of one or more polythiols in the composition. Such compositions may be formulated as multi-part systems, which are useful for the preparation of coatings and sealants.

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.
