Summary: | The invention relates to a cationically curable composition with at least one cationically polymerizable component, a first photoinitiator releasing an acid when irradiated with actinic radiation of a first wavelength λ1, and a second photoinitiator releasing an acid when irradiated with actinic radiation of a second wavelength λ2, wherein the second wavelength λ2 is shorter than the first wavelength λ1, and wherein the second photoinitiator, after irradiation of the composition with actinic radiation of the first wavelength λ1, shows an absorption of actinic radiation of the second wavelength λ2 in the composition that is sufficient to activate the second photoinitiator and fix the composition. Furthermore, a method is described for the joining, casting, molding, sealing and/or coating of substrates using the cationically curable composition. |
