WATER BORNE CROSSLINKABLE COMPOSITIONS |
摘要 |
This invention relates to improved water-based polymeric dispersions having suitability for coatings and other applications which are based upon polymers having a plurality of acetoacetate functional groups and a crosslinkable component comprising a plurality of aromatic aldimine. The basic acetoacetate/benzaldimine containing system comprises an aqueous polymeric dispersion wherein the polymer has a plurality ofacetoacetate groups and an effective amount of a curing agent having a plurality of benzaldimine functional groups. The improvement in providing for water-stable polymeric dispersions suitable for coatings and other applications comprises an aqueous dispersion comprising a polymeric component preferably derived from a plurality of polymerizable ethylenically unsaturated monomer units having pendant araldimine or heterocyclic aldimine functionality. Acetoacetate containing monomers generally are used in forming the polymer and a preferred monomer acetoacetoxyethymethacrylate. The polymer incorporating a plurality of benzaldimine functionality generally is formed by emulsion or suspension polymerization and the adimine functionality is benzaldimine.
