Abstract

A process for forming a shaped laminate for use in a safety glazing such as a vehicle window or the like which comprises lightly bonding at least one flexible, transparent, thermoplastic carrier layer having one or more adherent functional performance layers or coatings on its surface to at least one layer of ptasticized polyvinyl butyral to form a premolding composite, stretching the composite to impart compound curvature thereto and form a shaped, shrinkable laminate, subjecting the shaped laminate to elevated temperature while constraining its edges to relieve stresses in the carrier layer, and cooling the shaped laminate while maintaining its edges constrained.
