LINING FILM FOR MULTILAYER GLASS AND MULTILAYER GLASS Russian patent published in 2019 - IPC C03C27/12 B32B17/10 B32B27/30 

FIELD: automotive industry.

SUBSTANCE: disclosed is lining film for multilayer glass, which can be used for automobiles, railway and other transport vehicles, in glazing buildings. Interlayer film for multilayer glass has single-layer structure or structure with two or more layers. Interlayer film as a whole contains polyvinyl acetal resin, plasticizer, light stabilizer based on sterically hindered amine and phosphorus-containing oxidation inhibitor. First layer has glass transition temperature greater than or equal to 32 °C in case the laying film contains only the first layer, and in case, when the spacer film comprises a first layer and a second layer and is or not provided with a third layer, at least one layer from the second layer and the third layer has a glass transition temperature greater than or equal to 32 °C.
