摘要： The present invention relates to aqueous alkyd resin dispersions comprising a) a short oil alkyd resin comprising, in its fatty acid component a1), at least one polyunsaturated fatty monoacid a11) having at least two unsaturations per molecule and comprising at least 35% by weight of a monoacid a111) having conjugated unsaturations, the content by weight of said fatty monoacid a111), with respect to said alkyd resin, being at least 5%, preferably from 5% to 40% and more preferably from 5% to 35%, and b) at least one anionic phosphate surfactant. The invention also covers a preparation process and its use in decorative coatings. The coatings based on these aqueous dispersions exhibit improved performance qualities in resistance to blocking and yellowing, in development of hardness and in gloss.

摘要： The invention relates to a polyester resin which is based on at least one fatty acid, with zero oil length (0%) or an oil length of between 0 and 35%, with a weight ratio of oxidizable fatty acids (monoacids), relative to the overall fatty acids, of 0 or greater than 0 and ranging up to 1, and which is based on an acid component comprising, in addition to the fatty acid, from 30% to 85% by weight, relative to the total weight of said resin, of rosin and/or of derivatives thereof bearing at least one carboxylic acid function.
