Laminate for a safety glazing

DETAILED DESCRIPTION Now, improvements have been made in plastic laminates for use in safety glazings having compound curvature and enhanced performance properties which mitigate wrinkling problems encountered in the prior art.
Accordingly, a principal object of this invention is to provide a laminate containing enhanced functional performance layer(s) or coating(s) which displays minimal or no edge wrinkling during laminating formation of a safety glazing.
Another object is to provide a plastic laminate usable in a conventional deairing/autoclave laminating operation to form a substantially wrinkle-free vehicle window having compound curvature.
Other objects will in part be obvious from the following description and claims.
These and other objects are accomplished by providing a flexible, draw-formed laminate for a safety glazing comprising a transparent, thermoplastic carrier film, preferably polyethylene terephthalate, which is shrink-stable during laminating formation of said safety glazing, bonded to at least one layer of plasticized polyvinyl butyral, such film having a greater tensile modulus than that of the layer of plasticized polyvinyl butyral.
