Aqueous coating compositions and articles coated thereby.

摘要

Aqueous coating compositions are known which comprise as film-forming components
[I] a water soluble or water-dispersible resin (i) obtained by copolymerizing
(A) a fatty acid-modifier acrylic monomer
(B) an alpha , beta -ethylenically unsaturated carboxylic acid, and
(C) an unsaturated monomer having a Q value in the Q-e theory of at least 0.1, and
[II] a vinyl polymer emulsion as a dispersion stabilizer.
The invention provides coating compositions which have the advantages that they are inexpensive and that they provide coated films of good water-resistance even when not completely dried, wherein the fatty acid-modified monomer (A) is composed of the reaction product between an unsaturated fatty acid having at least two non-conjugated double bonds and a hydroxyl-containing ester of acrylic or methacrylic acid and the vinyl polymer emulsion (II) has been obtained by polymerizing an unsaturated vinyl monomer in the presence of a water-soluble oxidation-curable resin (ii).
