A reaction resin mixture, which is able to be hardened thermally and by means of UV radiation, contains the following constituents:

Reaction resin mixture comprising epoxy resin, benzylthiolanium salt and

Siliconimides, which contain cross-linkable, functional groups, having the general formula ##STR1## in which the Q residues contain the functional groups.

Siliconimides

In a process for coating or bonding electronic components and subassemblies with reaction resin mixtures that are stable in storage at room temperature as a one-component system for several months, reaction resin mixtures are used, which contain the following components:
