Claims
- 1. A hardenable composition containing a) an organic material which can be polymerized cationically and b) a composition containing
- i) an anhydride of a polycarboxylic acid, a polyisocyanate, a cyclic carbonate, a lactone or a mixture of such compounds, and dissolved therein
- ii) at least one compound of the formula I
- [M.sup.+n (L).sub.x ].sup.n+ nX.sup.- (I)
- in which n is 2 or 3, M is a metal cation selected from the group consisting of Zn.sup.2+, Mg.sup.2+, Fe.sup.2+, Co.sup.2+, Ni.sup.2+, Cr.sup.2+, Ru.sup.2+, Mn.sup.2+, Sn.sup.2+, VO.sup.2+, Fe.sup.3+, Al.sup.3+ and Co.sup.3+, X.sup.- is an anion which is selected from the group consisting of AsF.sub.6.sup.-, SbF.sub.6.sup.-, BiF.sub.6.sup.- and derivatives derived from these anions in which a fluorine atom or atoms is replaced by hydroxyl group or hydroxyl groups, or in which up to 50% of the anions X.sup.-, based on the total amount of anions, can also be any desired anions, L is water or an organic .sigma.-donor ligand which contains, as ligand sites, one or more functional radicals selected from the group consisting of --CO--, --CO--O--, --O--CO--O-- and --O--, and which forms .sigma.-bonds with the central atom via the oxygen atom or via the oxygen atoms, and x is an integer from 0 to 6, it being possible for the ligands L to differ within the context of the definitions given.
- 2. A composition according to claim 1, in which the amount of initiator component b) is 0.05 to 0.5 part by weight, per part by weight of the material which can be polymerized cationically.
- 3. A composition according to claim 1 containing a compound having on average at least two 1,2-epoxide groups per molecule as component a).
- 4. A process for the preparation of a hardened product, which comprises hardening a hardenable composition according to claim 1 by heating.
