ABSTRACT:
A novel complexer for use in aqueous coating compositions formed from acidic resins, as well as the coating compositions, are described. The complexer is formed from a metal having a coordination value in excess of its valence and a polyalkylene polyamine along with, optionally, organic acids and cometals. The acidic resin, partially neutralized with ammonia, is added to the formed complexer to form the coating composition, a coordinate, which, upon drying, provides films which are water resistant and have excellent wet rub resistance. The coating compositions are particularly useful for inks, including gravure and flexographic inks.
