ABSTRACT:
Aqueous-borne coating compositions containing:
(A) an acetoacetylated polymer; and
(B) a polyacrylate having at least two (meth)acrylate end groups,
have long pot lives and may be cured by the evaporation of water in the presence of a basic catalyst. Acrylic copolymers having pendent urethane side groups which are terminated with (meth)acrylate groups are water-dispersible and may be cured with polyfunctional crosslinking agents or by free radical initiators to afford coatings having excellent properties. Incorporation of a crosslinking component containing epoxy groups improves the coating properties.
