Title:
HEAT-INSULATING GLASS
Document Type and Number:
WIPO Patent Application WO/2016/208444
Kind Code:
A1
Abstract:
In a heat-insulating glass having a glass plate and a heat-insulating coating film provided on a first surface of the glass plate, the heat-insulating coating film is constructed from three or more layers including a conductive tin oxide-containing layer, the heat-insulating glass has suppressed yellowness and redness, and the heat-insulating glass has a maximum of one location where the sign of the first derivative obtained changes from positive to negative when measured in a state in which the heat-insulating coating film side is brought into contact with an integrating sphere detector and the glass plate side is brought into contact with white paper and in a state in which the glass plate side is brought into contact with an integrating sphere detector and the heat-insulating coating film side is brought into contact with white paper and the spectral reflectance spectrum curve is linearly differentiated in the wavelength range of 380-550 nm.
