Abstract
Water-thinnable, di- or polyesters and water-insoluble coatings which are particularly suitable as wood finishes and which are made by reaction of the di- or polyesters with water-soluble aminoplast resins are described. The ester resin intermediates are made by reacting a triol having a carbon/oxygen ratio of about 5:3 to about 7:3 with a polycarboxylic acid selected from lower molecular weight polycarboxylic acids so that the resulting ester resin is water-thinnable. The ratio of triol to polycarboxylic acid is varied to produce either the diester or the polyester.
