Abstract

The present invention relates to a method for preparing an optic material by depositing on a substrate at least two layers of inorganic polymeric material, each of these layers containing at least one metal oxide or metalloid oxide, the deposited layers being densified cross-linked by exposure to ultraviolet rays. The invention also concerns the optic material which may be prepared using this method. The optic materials which may be prepared using said method are in particular multilayer materials such as antireflective materials and reflective materials.
