INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS

摘要

An interlayer for laminated glass is provided, with which transparency can be improved. When an interlayer for laminated glass according to the present invention is observed using a transmission electron microscope, a sea-island state having a sea-like dark part and a plurality of island-like light parts is observed. A thermoplastic resin is included in the dark-part area. A thermoplastic resin is included in the light-part areas. Either the arithmetic mean value of the lengths of the light parts is not more than 400 nm, or the median value of the lengths of the light parts is not more than 400 nm.
