摘要:
An improved resin coated substrate is prepared by coating a suitable substrate, such as aluminum with a composition comprising a salt having the structure A-N.sub.2.sup.+ X.sup.- wherein A is an aromatic or heterocyclic residue and X is an anion of an acid; and a binder composition comprising both an acrylic polymer and an acid containing acrylic copolymer.
