The present invention provides a composition comprisinga) at least one epoxy resin,b) at least one cyclic amine of the formula (I)in whichR1 to R4 is H or an organic radical andX═-(Y1)m-(A1)n-(Y2)o-(A2)p-(Y3)q-(A3)r-(Y4)s-,  (II)where, independently of one another,m, n, o, p, q, r and s=0 or 1,A1, A2, A3=alkylene or alkenylene radical andY1, Y2, Y3, Y4=NR5, PR5, O or S, where R5 independently=organic radical,where any two organic radicals selected from R1 to R5 and any radicals present in the alkylene and/or alkenylene radicals A1, A2, A3 may also form one or more further rings,with the proviso that at least one of the radicals selected from R1 to R5 present and any radicals present in the alkylene and/or alkenylene radicals A1, A2, A3 is substituted by at least one -NHR6 or -NH2 group, where R6=organic radical, andc) 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.
