Hardenable epoxide resin mixtures containing a latent hardener, an amine and a thiol

A hardenable mixture, comprising

• (a) an epoxide resin,
• (b) a latent epoxide resin hardener which starts to react only at a temperature of at least 80.degree. C. (measured by DSC at a heating rate of 10.degree. C./minute),
• (c) an amine having at least two NH.sub.2 groups which is a cycloaliphatic amine or an aliphatic amine of one of the formulae I to VI ##STR7## in which R is a straight-chain or branched C.sub.2 -C.sub.10 alkylene radical, a is an integer from 1 to 10, b is an integer from 1 to 10, c,d and e independently of one another are an integer from 1 to 20, f is an integer from 1 to 5, and g is an integer from 1 to 10, and R.sub.1 is a trivalent radical of the formulae ##STR8## (d) a thiol having at least one SH group, either the amine (c) having at least two hydrogen atoms bound to one or more nitrogen atoms or the thiol (d) having at least two SH groups, and the difference between the reaction maxima for the amine/thiol and latent hardener reactions with the epoxide resin in the DSC diagram which results upon heating the hardener mixture at a heating rate of 10.degree. C./minute being at least 30.degree. C.
