A colored mirror includes a transparent substrate, a reflective metal layer and at least one interface layer between the substrate and the metal layer, wherein the interface layer includes at least one discontinuous metal layer, and at least one overlayer of a dielectric material deposited on the discontinuous layer. The discontinuous metal layer allows the adaptation of the color reflected by the mirror. The nominal thickness thereof and the type of material, as well as the nature and thickness of the dielectric overlayer, play a role in obtaining the color of the mirror.

Coloured mirror

A substrate is coated on one face with a thin-films stack having reflection properties in the infrared and/or in solar radiation including a single metallic functional layer, based on silver or on a metal alloy containing silver, and two antireflection coatings. The coatings each include at least one dielectric layer. The functional layer is positioned between the two antireflection coatings. At least one of the antireflection coatings includes an intermediate layer including zinc oxide ZnOwith 0.05&#x3c;x&#x3c;0.3 and having a physical thickness of between 0.5 nm and 20 nm, or between 2.5 nm and 10 nm.

Substrate provided with a stack having thermal properties and a superstoichiometric intermediate layer

A substrate is coated on one face with a thin-film multilayer including at least one metal functional film based on silver or made of silver having a thickness e of between 7 nm and 20 nm inclusive of these values, and two antireflection coatings. The antireflection coatings each include at least one antireflection film. The functional film is placed between the two antireflection coatings. The multilayer includes two discontinuous metal films each having a thickness e' of between 0.5 nm and 5 nm inclusive of these values. A lower discontinuous metal film is located between the face and the only or first metal functional film as counted starting from the face and an upper discontinuous metal film located above the only or last metal functional film as counted starting from the face.
