Abstract
In a selectively light-transmitting laminated structure composed of PA1 (1) a substrate layer (A) of a transparent sheet-like structure, PA1 (2) a heat wave-reflective layer (D) of a silver-containing metal having a thickness of 50 to 300 .ANG. formed on layer (A), PA1 (3) either a transparent thin layer (B.sub.1) having a high refractive index placed between layers (A) and (D), or a transparent thin layer (B.sub.2) having a high refractive index on layer (D), or both layers (B.sub.1) and (B.sub.2), and PA1 (4) optionally, a transparent top layer (E) on layer (D); the improvement wherein a thin layer (C) having a thickness of 3 to 100 .ANG. and deposited as a material selected from the group consisting of Ti, Zr, In, Si, C, Co and Ni is provided on layer (D) in contact therewith.
