Title:
WINDOW MATERIAL AND TRANSLUCENT ROOF MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/182499
Kind Code:
A1
Abstract:
Provided are: a window material or a translucent roof material that is capable of autonomously changing the degree of cloudiness thereof according to the temperature, that does not have a complex structure, and is easy to produce; and a building, vehicle, ship, or aircraft provided with said window material and/or translucent roof material. This window material or translucent roof material is provided with at least one translucent base material layer and at least one tacky layer, wherein: the tacky layer comprises a tacky composition containing 1-100 parts by mass of temperature-sensitive microparticles with respect to 100 parts by mass of a pressure-sensitive adhesive; the refractive index of the temperature-sensitive microparticles decreases with increases in temperature; and the refractive index rate decrease, which is the amount of decrease in refractive index per 1℃, for the temperature-sensitive microparticles is greater near the melting point of the temperature-sensitive microparticles than in temperature ranges that are not near the melting point of the temperature-sensitive microparticles.
