Compositions are described containing (A) an epoxy resin having on average at least two 1,2-epoxy groups per molecule or a mixture of these epoxy resins, (B) a compound of the formula I or a mixture of these compounds [R1(FeIIR2)a](+)ab ab x [X](-) (I) in which a and b independently of one another are 1 or 2, R1 is a pi -arene, R2 is a pi -arene, an indenyl anion or a cyclopentadienyl anion, X(-) is an [LQm](-) or an anion of a partially fluorinated or perfluorinated aliphatic or aromatic sulfonic acid, L is B, P, As or Sb, Q is fluorine or some of the radicals Q can also be hydroxyl groups and m corresponds to the valence of L increased by one, and (C) a flexible polyester which is terminated by, on average, at least two carboxyl groups and which is derived from an aliphatic or cycloaliphatic polyol or a mixture of such polyols and from an aliphatic, cycloaliphatic or aromatic polycarboxylic acid or a mixture of such polycarboxylic acids. The compositions can be employed as coating agents or as adhesives. |
