Title: THERMOCHROMIC FILM AND THERMOCHROMIC COMPOSITE
Abstract:
The present invention addresses the problem of providing a durable thermochromic film exhibiting exceptional thermochromic properities. The thermochromic film has, in the stated order, an optical functional layer containing at least vanadium dioxide exhibiting thermochromic properties, an adhesive layer, and a separator; wherein the thermochromic film is characterized in that the adhesive layer and the separator are adjacent, and the distance between the surface of the optical functional layer on the side near the adhesive layer and the interface between the adhesive layer and the separator is set to a specific value.
