Storage-stable, homogeneous mixture containing epoxide resin, curing agent and curing accelerator, and the use of the mixture for producing cured products

A homogeneous mixture of epoxide resin, curing agent for the resin, and curing accelerator, which mixture contains

• (a) an epoxide resin having on average more than one epoxide group in the molecule,
• (b) as curing agent for the epoxide resin, a cyanoacetyl compound dissolved in the resin, which compound has a melting point (m.p.) below 120.degree. C. and corresponds to the formula I ##STR42## wherein R is the radical of a mono- to tetravalent alcohol or amine having a partial molecular weight of .ltoreq.2000, which radical is formed by removal of 1 to 4 hydroxyl hydrogen atoms or amine hydrogen atoms, and n is a number from 1 to 4 inclusive, the amount of (b) being such that to 1 --CH.sub.2 --C.tbd.N group there are 3-4 epoxide groups of the component (a), and
• (c) as curing accelerator, to 100 parts by weight of epoxide resin 0.1 to 10 parts by weight of a phenylurea derivative of the formula II ##STR43## in which Z is the group ##STR44## wherein A is --CH.sub.2 -- or N, p is 0, 1 or 2, and q is 1 or 2, and R.sub.1 and R.sub.2 independently of one another are each an alkyl group having 1 to 4 carbon atoms, and wherein R.sub.3 and R.sub.4 independently of one another are each hydrogen, halogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, or a substituted or unsubstituted phenyl or phenoxy group, and R.sub.5 is hydrogen, trifluoromethyl, nitro or one of the groups ##STR45##
