FIELD: process engineering.
SUBSTANCE: this invention relates to multilayer interlayers to be used in multilayer glass panels to decrease sound transmission and to create colour zone in gradient area. Sound effect is ensured by using two or more different-composition polymer sheets integrated into single multilayer interlayer while gradient zone effect is ensured by creating colour zone in one or more gradient zones of individual layers.
EFFECT: glass panel with PVB layers, stable optical properties.
