<p>PROBLEM TO BE SOLVED: To provide a glass laminate which is excellent in a heat ray reflection function and has a color tone of reflected light which is close to neutral (visually colorless).SOLUTION: A glass laminate comprising a glass plate and a heat ray reflection film having a metal layer containing silver as a main component on one of the principal surfaces of the glass plate. Visible light reflectance, visible light transmittance, and solar reflectance, defined by JIS R3106 (1998), which are measured on the other principal surface of the glass plate are more than 15%, more than 30% and less than 65%, and more than 40%, respectively. Moreover, chromaticity coordinates (x, y) in an XYZ color system in a 2-degree visibility, defined by JIS Z8722 (2009), of reflected light obtained by light made incident from a C light source at an angle of incidence of 5 degrees is (0.290≤x≤0.320, 0.290≤y≤0.330).</p> |
