Abstract

A reaction resin mixture, which is able to be hardened thermally and by means of UV radiation, contains the following constituents: PA1 a cationically polymerizable epoxide resin; PA1 a latent hardening initiator in the form of an aralkyl-thiolanium salt; and PA1 a 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.
