Composite material having a high refractive index, process for producing this composite material and optically active material comprising this composite material.

摘要

The invention relates to a composite material having a high refractive index, to a process for producing the same, and to optically active materials such as antireflection materials and reflecting materials made from this composite material. This composite material with a high refractive index is characterized in that it comprises colloids (1) of metal oxide embedded in a polyvinyl polymer (3), soluble in an alcoholic solvent.
