Abstract: A reaction resin mixture, which is able to be hardened thermally and by means of UV radiation, contains the following constituents:a cationically polymerizable epoxide resin;a latent hardening initiator in the form of an aralkyl-thiolanium salt; anda sensitizer of the structure ##STR1## A being --CO--, --NR-- and --CO--CO--, and D being --O--, --S--, --CO-- and --CH.sub.2).sub.x (where x= 1 or 2) or rather a single bond or two hydrogen atoms.

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

Abstract: 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:a cationically hardenable, solvent-free epoxy resin;a triarylsulphonium salt with hexafluorophosphate, -arsenate or -antimonate as anion, with a mass concentration of 0.01 to 5% (relative to epoxy resin); anda benzylthiolanium salt with hexafluorophosphate, -arsenate or -antimonate as anion, with a mass concentration of 0.01 to 5% (relative to epoxy resin);as well as possibly customary additives.These reaction resin mixtures are hardened through UV radiation and thermally.

Abstract: The invention relates to isocyanurate-containing, organosilicon compounds of the general formula ##STR1## in which Q=--(CH.sub.2).sub.3 SiR.sub.2 O(SiR.sub.2 O).sub.n SiR.sub.2 R', n is an integer from 0 to 25 and x is an integer from 0 to 10, and the following holds for the residues R and R', which can be the same or different:R=alkyl, cycloalkyl, aryl, arylalkyl or alkylaryl, andR'=an epoxy-functional residue with 4 to 10 C-atoms or a (meth)acrylate-functional residue with at least 6 C-atoms.
