Abstract
In one aspect, an optically responsive film in which liquid crystal is dispersed in a matrix that includes siloxane linkages. The film has a transmissivity at -20.degree. C. that is substantially the same as the transmissivity at 20.degree. C. and a V.sub.90 at -20.degree. C. that is less than twice the value at 20.degree. C. In another aspect, an optically responsive film in which liquid crystal is dispersed in a matrix that includes the polymerization product of at least one mercapto-functional siloxane. In another aspect, an optically responsive film in which liquid crystal is dispersed in a matrix that includes the polymerization product of at least one multi-functional ene and at least one multi-functional silicon hydride. In another aspect, an optically responsive film in which liquid crystal is dispersed in a matrix that includes the reaction product of at least one multi-functional vinyl silane and at least one multi-functional thiol.
