Abstract

Layered structures consisting of at least one film A containing a polyvinyl acetal PA and at most 16% by weight of plasticizer WA and at least one film B containing a polyvinyl acetal PB and at least 16% by weight plasticizer WB between two glass sheets, are produced by adhering at least one film A to at least one film B or at least one of the glass sheets by means of a liquid. The layered structure can then be pressed to form a composite glass laminate.
