PCT No. PCT/FR92/00814 Sec. 371 Date Apr. 25, 1994 Sec. 102(e) Date Apr. 25, 1994 PCT Filed Aug. 21, 1992 PCT Pub. No. WO93/04386 PCT Pub. Date Mar. 4, 1993.A material having antireflection properties, and a method of depositing an antireflection coating on a substrate, are disclosed. In order to obtain a coating having simultaneously antireflection, hydrophobic and abrasion resistance properties, a material is used comprising: an organic or inorganic substrate (2); an adhesion promoter layer (4) of a material selected from silanes; an antireflection coating (6) formed from colloids of silica in a siloxane binder; a coupling agent layer (8) of a material selected from silazanes; and an anti-abrasion layer (10) of a fluorinated polymer. These materials have specific applications in optics.
