Abstract

Organosilicon polymers, including crosslinked polymers and crosslinkable prepolymers, of cyclic polysiloxanes, organic dyes, and, optionally, polyenes. The dyes include those with delocalized Pi electron systems linking electron donor groups and electron acceptor groups, and with at least two carbon-carbon double bond-containing pendant groups attached to at least two different sites from among the indicated delocalized Pi electron systems, donor groups, and acceptor groups.
