Abstract
Provided is a solar control composition comprising an infrared absorbing phthalocyanine, naphthalocyanine or rylene compound and an ethylene acid copolymer or an ionomer of an ethylene acid copolymer. Further provided are solar control laminates comprising the solar control composition of the invention.
Claims14
A solar control laminate comprising a solar control layer and at least one additional layer, said solar control layer comprising a solar control composition, and said solar control composition comprising at least one infrared absorbing naphthalocyanine or rylene compound and an ethylene acid copolymer or an ionomer of an ethylene acid copolymer;
- wherein the at least one infrared absorbing naphthalocyanine or rylene compound is soluble in the solar control composition.
A solar control laminate comprising a solar control layer and at least one additional layer, said solar control layer comprising a solar control composition, and said solar control composition comprising an ethylene acid copolymer or an ionomer of an ethylene acid copolymer and a concentration of an infrared absorbing naphthalocyanine or rylene compound;
- wherein said infrared absorbing naphthalocyanine or rylene compound is soluble in said solar control layer;
- wherein said solar control laminate has a layer thickness, a level of transmission of solar light and a level of transmission of visible light such that when the laminate is simulated using Simulation Method A, the simulated level of transmittance of visible light, Tvis-sim, and the simulated level of transmittance of solar light, Tsol-sim, are such that for a naphthalocyanine compound 0.65<Tvis-sim<0.75 and Tsol-sim<(0.472(Tvis-sim)−0.150) and for a rylene compound 0.65<Tvis-sim<0.75 and Tsol-sim<(1.719(Tvis-sim)−0.801).
