Abstract
A method of reforming an interlayer film for heat-insulating laminated glass by which an interlayer film for heat-insulating laminated glass capable of exhibiting an excellent optical property may be obtained even if heat-insulating fine particles covered with an inert substance are used, an interlayer film for heat-insulating laminated glass, and laminated glass is provided. The method comprises irradiating an interlayer film for heat-insulating laminated glass comprising a heat-insulating fine particle covered with an inert substance, a matrix resin, and a liquid plasticizer with a high energy ray comprising an electromagnetic wave having energy of 3.0 eV or more to improve transmittance of visible light having a wavelength of 380 to 780 nm, and also to reduce transmittance of a near-infrared radiation having a wavelength of 780 to 2100 nm.
