The present invention provides a composition comprisingn a) at least one epoxy resin, b) at least one cyclic amine of the formula (I) nn n n n n n n n n n in whichn R 1 to R 4 is H or an organic radical and n n n n X═—(Y 1 ) m -(A 1 ) n -(Y 2 ) o -(A 2 ) p -(Y 3 ) q -(A 3 ) r -(Y 4 ) s —, (II)n where, independently of one another,n m, n, o, p, q, r and s= 0 or 1, A 1 , A 2 , A 3 =alkylene or alkenylene radical and Y 1 , Y 2 , Y 3 , Y 4 =NR 5 , PR 5 , O or S, where R 5 independently=organic radical, where any two organic radicals selected from R 1 to R 5 and any radicals present in the alkylene and/or alkenylene radicals A 1 , A 2 , A 3 may also form one or more further rings, with the proviso that at least one of the radicals selected from R 1 to R 5 present and any radicals present in the alkylene and/or alkenylene radicals A 1 , A 2 , A 3 is substituted by at least one —NHR 6 or —NH 2 group, where R 6 =organic radical, and n c) at least one salt of a very strong Brønsted acid with a counterion selected from metal ions, metal-containing ions, phosphonium ions and unsubstituted ammonium ions, and to processes for production thereof and use thereof. |
