Claim Text:
1. An organo-siloxane composition, which has a backbone containing —Si—O— units with chromophore groups attached directly to at least a part of the silicon atoms and which consists of a repeating —Si(R 1 2 )—O—Si(R 2 2 )—O— backbone, wherein each R 1 is independently selected from the group of hydrogen, hydroxy, linear or branched alkyl, alkoxy, alkenyl, alkynyl, epoxy, vinyl, allyl, tolyl, anisyl, acryl, acrylate, alkyl(alk)acrylate and aryl groups, at least one of the R 1 s in each repeating —Si(R 1 2 )—O—Si(R 2 2 )—O— group in the —Si(R 1 2 )—O—Si(R 2 2 )—O— backbone being a polycyclic aromatic chromophore group, and wherein each R 2 is independently selected from the group of hydrogen, hydroxy, alkyl, alkoxy, alkenyl, alkynyl, epoxy, vinyl, tolyl, acryl, acrylate, alkyl(alk)acrylate and aryl groups.
