    摘要： The invention is directed to gassing stabilized aqueous coating compositions comprising

    A) a metallic pigment and at least one reaction product of:

    (a) 5 to 95 weight percent of a at least one phosphonic acid derivative selected form compound I and II
    wherein R 1 is H or O=P(OH) 2 ; R 2 and R 3 are independently H, OH or an aliphatic, cycloaliphatic and aromatic substituent having 1 to 25 carbon atoms and optionally up to 10 heteroatoms of at least one of oxygen and phosphorus; and R' is an aliphatic, cycloaliphatic and aromatic substituent having 1 to 25 carbon atoms and optionally up to 10 heteroatoms of at least one of oxygen and phosphorus;
    (b) 5 to 95 weight percent of a at least one compound having at least two epoxy groups and a number average molecular weight Mn of 300 to 5000 g/mol; and
    (c) 0 to 90 weight percent of a compound having one epoxy-functional group, wherein the proportions by weight of components (a), (b) and (c) total 100 weight percent.

    B) at least one metallic pigment.
