Flexibilized, light-initiated curing epoxy resin composition consisting of (A) 20 to 95% by weight of a mixture of cycloaliphatic and aliphatic compounds containing at least one epoxy group, (B) - 4.89 to 73 wt .-% of at least one hardened epoxy resin composition flexibilizing compound of the general formula I. wherein m = an integer from 40 to 300, n = an integer from 1 to 5, R 1 = H or C 1 -C 4 -alkyl, R 2 and R 3 , independently of one another, with alkyl = C 1 -C 15 and R 4 = a bivalent, organic alkylene radical having 4 to 10 C atoms, (C) - 0.1 to 2% by weight of a ferrocenium hexafluoroanthi months as a photoinitiator, (D) 0.01 to 5% by weight of an accelerator, (E) - and 0 to 40 wt .-% of excipients, modifiers, (meth) acrylic groups containing monomers, (meth) acrylic groups containing prepolymers and / or decomposing under radical formation compounds. |
