Abstract
The invention relates to the use of an infrared absorber for accelerating the UV curing of a mass to be cured. The infrared absorber is preferably selected from ATO, ITO, ZnO, LaB6 and a mixture of said substances. A casting resin is preferably used as the mass to be cured, in particular a resin based on an acrylic resin or an acrylate resin. The invention permits the production of laminated panes, in which the starting mass is applied between the panes and converted to form the laminate.
Claims6
A curable acrylic or acrylate resin composition comprising:
- a substantially transparent infrared absorber selected from ATO, ITO, ZnO, LaB6 and a mixture of these substances in a total amount of from 0.005% to 5% by weight of the composition for accelerating the UV curing of the composition.
A substantially transparent infrared absorbing composition to be used in a resin comprising from about 0.005% to about 5% by weight of the composition of a material selected from the group consisting of ATO, ITO, ZnO, LaB6 and mixtures thereof, said material being capable of accelerating the UV curing of the resin.
