ABSTRACT:
The invention is an optically transparent organopolysiloxane resin with a large amount of a uniformly dissolved and dispersed optically-functional organic material. The compatibility of the optically functional material is achieved by modifying it by addition of alkoxysilylalkyl groups to aromatic groups of optically-functional organic compounds such phthalocyanines, porphyrins, tetraphenylbutadienes, axobenzenes, bis(4-dimethylaminodithiobenzyl)nickel and anthracenes. The compositions contain 20 to 200 parts by weight of the modified optically-functional organic compounds per 100 parts by weight of the organopolysiloxane resin. The composition may be formed into a specified shape, solvents evaporated, and cured by heat.
