Abstract: 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).

Abstract: The invention relates to an optical article having antireflection properties, optionally antistatic properties, having a high thermal and abrasion resistance, as well as the method for producing the same. The article of the invention comprises a substrate and, starting from the substrate: a sub-layer comprising a SiO2-based layer, said SiO2-based layer having a thickness greater than or equal to 75 nm et free from Al2O3; and a multilayered antireflection coating comprising a stack consisting in at least one high refractive index layer and at least one low refractive index layer, all the low refractive index layers of which comprising a mixture of SiO2 and Al2O3, and the high refractive index layers of which are not layers that do absorb in the visible region comprising a substoichiometric titanium oxide and reducing the relative visible light transmission factor (Tv) of the optical article by at least 10% as compared to a same article without any of said visible light absorbing layers.

Abstract: The present invention relates to an optical article having anti-reflection properties and high thermal resistance, comprising a substrate having at least one main face coated with a multi-layer anti-reflection coating comprising a stack of at least one high refractive index layer and at least one low refractive index layer, wherein the ratio: R T = sum ⁢⁢ of ⁢⁢ the ⁢⁢ physical ⁢⁢ thicknesses ⁢⁢ of ⁢⁢ the low ⁢⁢ refractive ⁢⁢ index ⁢⁢ layers ⁢⁢ of ⁢⁢ the ⁢ anti ⁢ - ⁢ reflection ⁢⁢ coating sum ⁢⁢ of ⁢⁢ the ⁢⁢ physical ⁢⁢ thicknesses ⁢⁢ of ⁢⁢ the high ⁢⁢ refractive ⁢⁢ index ⁢⁢ layers ⁢⁢ of ⁢⁢ the ⁢ anti ⁢ - ⁢ reflection ⁢⁢ coating is higher than 2.1. If the anti-reflection stack comprises at least one low refractive index layer having a physical thickness ≧100 nm which is not the outermost layer of the anti-reflection coating, said relatively thick layer and the underlying layers are not taken into account in RT calculation.
