Water-borne coating compositions containing metallic pigment having reduced tendency to gas generation on storage.

摘要

The tendency of metallic pigments, especially of aluminium flake pigments, to react with the aqueous medium of a water-borne paint composition with the generation of gaseous material is prevented or reduced by incorporating in the composition an agent containing in the molecule at least one P-OH group, or a salt derivative thereof, which is obtained by reacting a compound containing the grouping -0-PO(OH<Sub>2</Sub>) with one or more epoxide group-containing compounds at least one of which also contains at least one aromatic or alicyclic group.
