Abstract
The present invention relates to compositions (self-thermally) curable on demand under the triggering action of UV-visible to near-infrared irradiation of moderate intensity, method of using same for accelerated photopolyaddition of cyclic ether-amine resins or ultrafast dark curing of cyclic ether-amine resins, and articles obtained by such method. The invention also relates to a resin casting, film or coated substrate, and an adhesive layeror bonding agent, comprising acyclic ether-amine resin obtained by an accelerated curing process according to the invention. The invention additionally relates to the use of a composition of the invention for increasing the delamination strength of laminated composite materials.
