Abstract
A laminated glass, a method for producing a laminated glass, and a reflective film that has end parts where the generation of wrinkles is prevented in a case where the laminated glass is produced by sandwiching the reflective film between two glass plates and that has a reflection wavelength range with a small variation are provided. The reflective film has wavelength-selective reflectivity. A thermal shrinkage rate in a case where the reflective film is held at 140° C. for 30 minutes is greater than 0.5% and smaller than 2.0%. The reflective film has at least one cutout portion on a side edge of the reflective film.
Claims17
A reflective film having wavelength-selective reflectivity,
- wherein an average thermal shrinkage rate in a case where the reflective film is held at 140° C. for 30 minutes is greater than 0.5% and smaller than 2.5%,
- the reflective film has at least one cutout portion on a side edge of the reflective film when viewed from a direction perpendicular to a main surface of the reflective film,
- the cutout portion has a curved portion when viewed from the direction perpendicular to the main surface of the reflective film, and
- a minimum curvature radius of the curved portion is 100 mm or greater and 900 mm or smaller when viewed from the direction perpendicular to the main surface of the reflective film.
A laminated glass comprising:
- two glass plates;
- and
- a reflective film disposed between the two glass plates,
- wherein the reflective film has wavelength-selective reflectivity,
- the reflective film has at least one cutout portion on a side edge when viewed from a direction perpendicular to a main surface of the reflective film,
- the cutout portion has a curved portion when viewed from the direction perpendicular to the main surface of the reflective film, and
- a minimum curvature radius of the curved portion is 100 mm or greater and 900 mm or smaller when viewed from the direction perpendicular to the main surface of the reflective film.
