Preparation of thin layers based on an oxide of feriii to the optical recording and / or magnetic

摘要

P the present invention relates to a process for the preparation of thin layers based on oxide fe * * i * * i * * i / p & & p & it consists in applying on a support a polymer composition of iron oxide prepared by hydrolysis of a solution of iron alkoxide. The hydrolysis by gradual release of water in a solution of the alkoxide of iron in a hydrophobic solvent, from the inverse micelles formed of water and a surfactant. / p & & p & the invention applies to the preparation of thin layers by the optical recording and / or magnetic. / p
