Abstract:
Laminated glass is produced by laminating at least one film A, having a glass transition temperature TA and containing a polyvinyl acetal PA and optionally at least one plasticizer WA, and at least one film B, having a glass transition temperature TB and containing a polyvinyl acetal PB and at least one plasticizer WB, between two glass sheets, wherein, before the lamination process, film A has a proportion of plasticizer WA of less than 24% by weight, film B has a proportion of plasticizer WB of at least 24% by weight, and film A has a thickness of no more than 30% of the thickness of film B.
