摘要

Optical article (I) comprises a transparent substrate made up of organic or mineral glass, comprising main phases, which comprises an anti-reflecting multi-layer coating comprising two layers (titanium oxide (under stoichiometric condition)) absorbing in the visible region such as the relative factor of transmission (Tv) of visible light reduced to 10 (preferably 80)% compared to (I) does not comprising the layers in the visible region. An independent claim is also included for the preparation of (I).
