LAMINATED GLASS, METHOD FOR MANUFACTURING PVB LAYER, AND METHOD FOR MANUFACTURING LAMINATED GLASS

摘要

The present invention suppresses a degradation in the viewability of a HUD image. This laminated glass (1) comprises: a first glass base body (12); a second glass main body (14); a reflective layer (16) provided between the first glass main body (12) and the second glass main body (14); and a PVB layer (20) which is provided between the second glass base body (14) and the reflective layer (16) and is composed of a polyvinyl butyral resin. In the laminated glass (1), the thickness (D5) of the PVB layer (20) is 2-25 μｍ, the longitudinal radius of curvature of the laminated glass (1) is no greater than 20,000 mm, the transverse radius of curvature of the laminated glass (1) is no greater than 10,000 mm, and the bubble remaining rate of the laminated glass (1) is no greater than 2%.
