INTERMEDIATE FILM FOR LAMINATED GLASS AND LAMINATED GLASS Russian patent published in 2018 - IPC C03C27/12 B32B17/10 

FIELD: technological processes.

SUBSTANCE: invention relates to an interlayer film for laminated glass. Intermediate film for a laminated glass includes a plastic layer that has Young's modulus of 1 GPa or more and a first polymer layer that is laminated on a first surface of the plastic layer. Second polymer layer may be laminated on the second surface of the plastic layer opposite to the first surface of the plastic layer. In the cross section in the direction of the thickness of the film of the intermediate layer, a first lamination interface is observed between the plastic layer and the first polymer layer, wherein the proportion of the length of the plastic layer in the first lamination interface that does not come into contact with the first polymer layer, relative to 100 % of the total length of the plastic layer in the first lamination interface, is less than or equal to 75 %.

EFFECT: higher adhesion between the plastic layer and the polymer layer, as well as improved suitability of processing laminated glass.
