METHOD FOR PRODUCING MULTILAYER GLASS WITH A POLARIZATION-SELECTIVE COATING Russian patent published in 2021 - IPC B32B17/10 

FIELD: material engineering.

SUBSTANCE: claimed group of inventions relates to a method for obtaining multilayer glass for a vehicle, as well as to a method for obtaining a projection device for a vehicle. According to the method for obtaining multilayer glass, a polarization-selective coating is obtained on a film substrate. The polarization-selective coating is transferred from the film substrate to the connecting film, for which the film substrate and the connecting film with the coating located between them are placed on top of each other to form a package of films. The film package is processed for 2-4 hours under a pressure from 8 bar to 15 bar (0.8-1.5 MPa) and a temperature from 80°C to 120°C in an autoclave. The film substrate is separated from the connecting film, and the coating remains on the connecting film. The connecting film is placed by area between the first plate and the second plate. The first plate and the second plate are laminated through a connecting film to form a multilayer glass.

EFFECT: group of inventions provides an increase in optical qualities in the resulting multilayer glass.
