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.

Glazing

A laser can be used to modify a glazingso as to improve its suitability for use with a signal-receiving deviceor a signal-transmitting deviceThis is done by using the laser to provide a region of reduced opacityto the signal within the glazing. Preferably, the laser is be used to reduce the opacity of a selected regionof a tinted interlayer in situ. The glazing may be for a vehicle, especially an automotive vehicle.

A laminated glazing comprising two panes of glazing material, a sheet of interlayer material extending therebetween, and an electrically conductive member formed (possibly etched) from a sheet of electrically conductive material also positioned between the panes. The electrically conductive member may function as one or more of: an antenna element, a capacitive sensor, an electromagnetic shield, part of alarm circuitry, a resistance thermometer, a busbar. Also a method of manufacturing such a glazing involving locating a pre-formed electrically conductive member and a sheet of interlayer material on a first pane of glazing material, placing a second pane of glazing material in register with the first so that the electrically conductive member and the interlayer material are between the two panes, and laminating in an autoclave.
