Abstract
Abstract Aqueous, solution or emulsion, and solvent based compositions comprising a crosslinked vinyl addition polymer having methacrylaldimine crosslinking groups are useful as coatings, binders and adhesives. The polymers are prepared from a crosslinkable composition comprising (A) a vinyl addition homopolymer or copolymer of methacrolein and (B) a compound having at least two amine-function groups selected from primary amine and primary amine-generating groups. A method of use is described in which crosslinking is at ambient temperatures.
