Abstract
A film suitable for use as a light-modulating unit of a suspended particle device light valve, comprising a plurality of particles dispersed in a liquid suspending medium, distributed within an optionally crosslinked matrix polymer. The suspending medium is substantially immiscible with the matrix polymer, has a boiling point greater than about 100° C., has an electrical resistivity of at least about 0.8×10ohms per square, and has an in endex of refraction at 25° C. which differs from that of the matrix polymer by no more than about 0.002.
