摘要: Aqueous dispersions of polyesters or alkyd resins for coatings are prepared by co-condensation of 10 to 100 mol-%, calculated on the sum of polybasic carboxylic acids, of polybasic acids whose carboxyl groups are attached to secondary and/or tertiary carbon atoms. Said dispersions are excellently stable and yield coatings with outstanding properties.
