ABSTRACT:
Water-soluble acidic polyesters are prepared by reacting a hydroxy polycarboxylic acid, such as citric acid, with an alkylene oxide, such as propylene oxide, an alkylene glycol, or styrene oxide and polyesterifying to an acid number of about theoretical to about 25% above theoretical. A thermosetting coating comprises the acidic polyester and a conventional aminoplast in an aqueous vehicle. When the coating is applied to a substrate, such as label stock, and is thermoset, a durable high gloss varnish is produced.
