Abstract
It has now been discovered, according to the present invention, that interlayers comprising a blend of plasticized poly(vinyl butyral) and poly(cyclohexanedimethylene terephthalate-co-ethylene terephthalate) copolyester can be used to form interlayers having a pearly white appearance. Such interlayers are useful in applications in which a colored multiple layer glass interlayer is desirable.
