ABSTRACT:
Compositions containing(a) a liquid epoxy resin,(b) an aliphatic or cycloaliphatic primary monoamine and/or an aliphatic or cycloaliphatic disecondary diamine,(c) a latent curing agent for the epoxy resin (a) which does not react until temperatures above 70° C. (measured by means of DSC at a heating rate of 10° C./min),(d) a photopolymerizable compound and(e) a photoinitiator,the ratio of the number of equivalents of epoxy groups to that of polymerizable groups being 1:0.01 to 1:0.7, are suitable as impregnating resins.
