Abstract

Curable mixtures, containing, PA0 (a) at least one bisphenol diglycidyl ether based on bisphenol A, hydrogenated bisphenol A or bisphenol F, PA0 (b) as a curing catalyst, a colorless or slightly yellow solution of a metal complex compound of the formula I EQU ]Me(H.sub.2 O).sub.x (Lm).sub.y ].sup.2+ (A.sup..crclbar.).sub.2 (I), PA0 in which PA1 Me is a divalent metal from the group comprising Zn, Cd, Sn, Pb, Ca or Mg, PA1 Lm is a saturated cyclic ether having 5 to 7 ring atoms, a linear or cyclic saturated aliphatic ether compound or a mixture of the ether and the ether compound, the ether and the ether compound having a boiling point of at least 60.degree.
