The present invention relates to at least one cationically polymerizable component, a first photoinitiator that emits an acid when irradiated with actinic radiation of a first wavelength λ 1 and a second photoinitiator that releases an acid when irradiated with actinic radiation of a second wavelength λ 2 as having about the cationically curable composition, in which was the second wavelength λ 2 is the first wavelength is shorter than λ 1, the second photo initiator is, after irradiating the composition with actinic radiation of the first wavelength λ 1, activate the second photoinitiator and the composition Absorption of actinic radiation of a second wavelength λ 2 in the composition sufficient to fix Also disclosed are methods for bonding, casting, molding, sealing and/or coating substrates using the cationically curable composition. |
