| 摘要 |
The invention relates to graft copolymers a) which are obtainable from A) epoxy resins having an epoxide equivalent weight of at least 500, preferably at least 700, and/or phenoxy resins, B) carboxylic anhydrides containing at least one polymerizable, ethylenically unsaturated double bond per molecule, and from C) further ethylenically unsaturated monomers, at least some of which may, if desired, contain a carboxyl group, where the ratio between the weight of A) and the total weight of monomer components B) and C) is in the range from 90:10 to 10:90. The invention also relates to coating compositions based on the graft copolymers a), and to their use for coating packaging containers. |
