Abstract
The present application relates to a coating composition and wood article manufactured therefrom, the coating composition comprising: (A) a film-forming resin composition comprising a reactive donor capable of providing two or more nucleophilic carbanions, and a reactive acceptor comprising two carbon-carbon double bonds; (B) a catalyst for catalyzing the Michael addition crosslinking reaction between the reactive donor and the reactive acceptor, wherein at least one of the reactive acceptor and the reactive donor comprises an aromatic ring structure, and wherein the polymer formed by homopolymerization of the reactive acceptor has a Tg of 100° C. or higher.
