INTERLAYER FILM FOR THE MULTILAYER GLASS AND MULTILAYER GLASS Russian patent published in 2018 - IPC C03C27/12 B32B3/30 

FIELD: laminated products or materials.

SUBSTANCE: invention relates to the interlayer film for laminated glass. Interlayer film comprises two or more laminated onto each other polymer layers. On at least one of its surfaces interlayer film has numerous recesses and numerous convexities. Each of the recesses has profile of groove with continuous bottom. Adjacent to each other recesses run parallel to each other and form the regular line. On the having numerous recesses and numerous convexities surface, the recesses groove depth (Rzg), measured according to the JIS B-0601 (1994) standard, makes from 10 to 40 mcm. In addition, the averaged over 10 points roughness (Rz) of the polymer layer surface, having numerous recesses and numerous convexities surface, measured according to the JIS B 0601 (1994) standard, makes less than 2.7 mcm.

EFFECT: technical result is the deaeration properties improvement in the process of laminated glass manufacturing and prevention of the undesirable images occurrence.
