Abstract
Aqueous emulsions and a process for producing aqueous emulsions useful in air drying and stoving paints with improved stability over long periods are described. Fatty acid esters carrying ether-like bound polyethyleneglycol radicals are reacted with conventional alkyd resin raw materials to provide an alkyd resin intermediate which is esterified with an acidic vinyl copolymer carrying methacrylic acid and oil fatty acid radicals. The excellent stability characteristics of the products, despite the relatively low content of polyglycol of from 3 to 8%, is believed due to the substantially unsaponifiable linkage of the stabilizing groups to the resin molecule.
