Document Type and Number:
WIPO Patent Application WO/2017/033533
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a thermochromic film and a thermochromic composite which include vanadium dioxide particles having excellent thermochromic properties and durability. This thermochromic film has, on a transparent substrate, an optically functional layer that includes at least vanadium dioxide particles with thermochromic properties and a binder resin. The thermochromic film is characterized in that: the binder resin has a reactive functional group and is water-soluble; water content of the optically functional layer after being left to stand at 80°C and a humidity of 80% for 24 hours is in the range of 0.5-5.0 g/m2; and the thickness of the optically functional layer is in the range of 0.5-5.0 μm.
