摘要

The present invention relates to water-dilutable (water-thinnable) coating compositions containing A. A mixture of A1. 50-95% by weight of one or more oligomeric or polymeric polyaddition or polycondensation compounds having a mean molecular weight of from 200 to 20,000 and containing, per molecule, at least two hydroxyl groups and at least two primary and/or secondary amino groups, and A2. 5-50% by weight of a crosslinking agent which is reactive towards component A1, B. A mixture of B1. 90-99.9% by weight of one or more free-radical polymerisable compounds having a mean molecular weight of from 100 to 10,000 and containing, per molecule, at least two olefinic double bonds, and B2. 0.1-10% by weight of a free-radical initiator having a decomposition temperature in the range of 50-150 DEG C, where the mixing ratio between mixture A and mixture B is from 10:1 to 1:10, and mixture A is substantially chemically inert towards mixture B. Coating compositions of this type are suitable for use in electrodeposition coating.
