PCT No. PCT/FR94/00875 Sec. 371 Date Mar. 22, 1996 Sec. 102(e) Date Mar. 22, 1996 PCT Filed Jul. 13, 1994 PCT Pub. No. WO95/02835 PCT Pub. Date Jan. 26, 1995The invention relates to a composite material having a high refractive index, its production process, as well as optically active materials such as antireflection materials and reflecting materials manufactured from the composite material. This composition material with a high refractive index is characterized in that it comprises SiO2 or metal oxide colloids (1), coated in a polyvinyl material (3), soluble in a water-containing alcoholic solvent.
