INTERMEDIATE FILM FOR LAMINATED GLASS, LAMINATED GLASS AND METHOD OF INSTALLING LAMINATED GLASS Russian patent published in 2019 - IPC C03C27/12 

FIELD: glass.

SUBSTANCE: invention relates to an intermediate layer film for laminated glass. Film includes a reflection layer of infrared rays which reflects infrared radiation, a first polymer layer which is located on the first surface side of the reflection layer of infrared rays and comprises a thermoplastic resin, and second polymer layer, which is located on second surface side of reflection layer of infrared rays and contains thermoplastic resin. Transmission of infrared beams at wave length 780–2100 nm of the first polymer layer is 10 % or more higher than transmission of infrared beams at wave length 780–2100 nm of the second polymer layer.

EFFECT: technical result is improved heat-shielding properties and light transmission.
