Abstract
A laminated glazing comprises two plies of glass having an interlayer structure laminated therebetween. The interlayer structure comprises a first sheet of an interlayer material framing a suspended particle device film incorporated therein. The interlayer material is chosen to minimize the migration of the components of the interlayer material into the suspended particle device film. Preferably, the interlayer material does not contain plasticizers, or contains a plasticizer which does not diffuse into the suspended particle device film structure.
