HEAT-SHIELDING FILM, PRODUCTION METHOD THEREFOR, AND HEAT SHIELD USING SAID FILM

WIPO Patent Application WO/2016/088852

A1

The present invention provides a means with which it is possible to, in a heat-shielding film that includes a hard coat layer having heat-shielding properties, suppress appearance defects and separation of the hard coat layer during hot forming when adhering said film to a substrate such as curved glass. The present invention provides a heat-shielding film comprising: a substrate having a thickness of 10-100 μm; and a hard coat layer formed from the cured product of a hard-coat-layer coating fluid that is disposed on at least one surface of the substrate, and that includes (a) a cesium-containing composite tungsten oxide, (b) an ultraviolet-curable component including a tetrafunctional or lower multifunctional (meth)acrylate in the amount of 50 mass% or less with respect to the total mass of the ultraviolet-curable component, and (c) a photopolymerization initiator. The change in visible light transmittance of the film before and after a tape peeling test when said tape peeling test is performed following a heat treatment is 20% or less.
