Abstract
The invention provides a liquid coating composition curable at ambient temperature comprising an acetoacetate groups-containing addition polymer having a number average molecular weight of 1000-100,000, a glass transition temperature of 250.degree.-370.degree. K., a hydroxyl number of 0-200 and a content of acetoacetate groups of 3,5-45% by weight, the acetoacetate groups being present as ester of hydroxyalkyl acrylate, hydroxyalkyl methacrylate or allyl alcohol structural units, and a polyamine having primary and/or secondary amino groups and blocked with an aldehyde or ketone. A process for coating a substrate with such composition is also provided.
