PROBLEM TO BE SOLVED: To provide a weathering-resistant heat-shielding film for an outer surface of a window that has weatherability and has a stable ultraviolet absorption function.SOLUTION: The weathering-resistant heat-shielding film for an outer surface of a window has a UV-curable hard coat layer 3 including a silane-modified benzotriazole and an infrared reflective layer 2. The infrared reflective layer 2 is a layer composed of one or more layers in which a metal is sputtered and the metal is one or more kinds of metals or alloys selected from aluminum, silver, gold, nickel, cobalt and stainless steel; or alternatively titanium dioxide, tin oxide, indium oxide, zinc oxide, tungsten oxide or a metal oxide produced by doping each of the oxides with a dissimilar metal.SELECTED DRAWING: Figure 2 |
