metallpigment waessrige containing metal with a reduced tendency to evolution during storage.

摘要

The tendency of metallic pigments, especially of aluminum flake pigments, to react with the aqueous medium of a water-born 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 -O-PO(OH2) with one or more epoxide group-containing compounds at least one of which also contains at least one aromatic or alicyclic group.
