OPTICALLY ACTIVE FILM COMPOSITE

摘要

An optically active film composite including a polymeric film substrate coated with a layer of resin having a thickness of less than 6 microns and a pencil hardness of at least 2H, and which includes 30-60 % by weight of nanoparticles of ATO or ITO, and nanoparticles of a second metallic compound being an inorganic compound and absorbing light having a wavelength in the range of 700-1100 nm. The composite preferably has a VLT of at least 50 % and a %TSER of at least 35 % with a weighted UV absorption of less than 1 %.
