Abstract
Abstract A selectively light-transmitting laminated structure has a substracte layer (A) of a transparent sheet-like structure, bearing an infra-red wave-reflective layer (D) having a thickness of 50 to 300 A comprising silver-metal, a transparent thin layer (B having a high refractive index between layers (A) and (D) and/or a transparent thin layer (B 2 ) having a high refractive index on layer (D), and optionally a transparent top layer (E) on layer (B 2 ) if present or layer (D); with a layer (C) having a thickness of 3 to 100 A and deposited as a material selected from Ti, Zr, In, Si, C, Co and Ni being provided on layer (D) in contact therewith on the opposite side thereof to layer (A). Such laminates can be used in windows of buildings and in greenhouses.
