Abstract
A coated plastic film 5 possessing high transmittance for visible light and high reflectance for heat radiation is disclosed which comprises a carrier film 1 of a transparent polymer and a reflection metal layer 3 embedded between two dielectric layers 2 and 4. The reflection metal layer 3 is formed from a metal selected from the group comprising silver, gold, and copper, whereas dielectric layers 2 and 4 are metal nitride layers. This coated plastic film may be coated on each side with a polyvinyl butyral film to form a plastic laminate which is itself a constituent of a laminated safety glass pane.
