Abstract

A plastic adhesive layer used as an insert layer in laminated glasses and the laminated glasses containing the insert layer, the adhesive layer comprising a polyfunctional polyol component and a polyfunctional isocyanate component, wherein the polyol component is present in considerable excess and the numerical ratio of the isocyanate groups to the hydroxyl groups is between 0.2 and 0.6. The adhesive layer is particularly useful in soundproofing glasses and in safety glasses such as bulletproofing glasses.
