Definitions
- the invention relates to a material comprising a transparent substrate comprising a functional coating or a functional layer capable of acting on solar radiation and/or infrared radiation.
- the invention also relates to glazing comprising these materials as well as the use of such materials for manufacturing thermal insulation and/or solar protection glazing.
- the terms “functional coating or functional layer” means “capable of acting on solar radiation and/or infrared radiation", that is to say providing the material with an antisolar and/or low-emissive property.
- This property can be provided by a coating consisting of a stack of layers, typically an alternation of n metallic functional layer(s) and n+1 dielectric coatings.
- This property can also be provided by a lamination layer, typically based on PVB comprising an absorber in the infrared range.
- This property can also be provided by one of the transparent substrates made of glass or other material.
- glazings can be intended for both buildings and vehicles, in particular with a view to reducing the air conditioning effort and/or preventing excessive overheating, so-called “solar control” glazings.
- the solar factor “FS or g” corresponds to the ratio in % between the total energy entering the room through the glazing and the incident solar energy.
- Known selective glazing comprises transparent substrates coated with a functional coating comprising a stack of several metallic functional layers, each placed between two dielectric coatings.
- a functional coating comprising a stack of several metallic functional layers, each placed between two dielectric coatings.
- These functional coatings are generally obtained by a succession of deposits made by cathode sputtering possibly assisted by a magnetic field.
- the faces of a glazing are designated starting from the outside of the building and by numbering the faces of the substrates from the outside towards the inside of the passenger compartment or the room it equips. This means that the incident sunlight passes through the faces in increasing order of their number.
- Known selective glazing is generally double glazing comprising the functional coating located on face 2, that is to say on the outermost substrate of the building, on its face facing the spacer gas layer.
- the invention specifically relates to highly selective glazing, for example comprising complex functional coatings based on metallic functional layers, generally silver-based or transparent conductive oxide-based.
- Silver-based functional coatings are generally more efficient in terms of selectivity compared to other known infrared-reflecting functional coatings such as coatings comprising layers based on conductive oxide or based on other metallic layers or layers. absorbing in the IR.
- silver-based functional coatings are qualified as complex by the number of layers constituting them, by the nature of the materials constituting these layers and by the adjustment of the thickness of these layers.
- the complexity of functional coatings makes it difficult to obtain both good thermal performance and a particular aesthetic aspect, for example excellent color neutrality and good color stability at angles.
- Document WO 2006/043026 describes solar control glazing with very low light transmission, in particular laminated comprising a solar control coating (“low E”) on one face and an absorbing layer which absorbs radiation of higher wavelength at 400 nm, on another side.
- the absorbent layers described are based on Ti or NiCrN and TiN. It is specified that the absorption in the visible and the IR is substantially constant over the entire spectrum from 400 nm to 100 pm. The light transmissions obtained are 14 and 15%, which limits the applications of these glazings to privacy glazing. Thermal performance is not optimal.
- Imaging device such as digital still cameras: “imaging device such as digital still cameras”) is very different from solar control glazing.
- Document WO 2018/197821 discloses colored glazing composed of a clear glass substrate on which is deposited a colored coating, the colorimetric characteristics of which are easily adjustable and modifiable.
- the coating comprises metallic nanoparticles in an inorganic matrix of an oxide, for example TiOx:Ag.
- the colored coatings respectively exhibit a plasmon absorption peak at 550 nm, 480 nm, 520 nm and 610 nm (Examples A to D) and 490, 440 and 420 nm (Examples E to G).
- plasmonic is meant absorption linked to plasmonic resonance effects of silver nanoparticles in a dielectric matrix.
- the object of the invention is to develop a sunscreen glazing, whose transmission is between 30 and 70%, having both improved thermal performance, in particular very high selectivity, while guaranteeing the desired aesthetic appearance, that is to say the most neutral appearance possible, in particular not green or yellow in transmission.
- the aim of the invention is therefore to obtain a range of glazing with very high selectivity while retaining the aesthetic appearance of the glazing, in particular its light transmission must be as neutral as possible.
- the solution proposed consists in adding, to a layer or to one of the elements of the glazing (substrate or interlayer of lamination), a particular absorbing element which absorbs solar radiation in the visible part of the spectrum in a specific way and which makes it possible to improve the thermal performance while not negatively impacting aesthetic requirements.
- the absorbent element is such that the glazing comprising the material according to the invention has an absorption profile with at least two absorption zones in the visible, one between 630 and 780 nm and the other between 480 and 550 nm.

- photoreceptors in the retina There are three types of photoreceptors, each of which exhibits spectral sensitivity to a region of the color spectrum: cones more sensitive to blue light (peak centered at around 420 nm), others to green light (peak centered at 530 nm ) and the third type of cones in red light (peak centered at 565 nm).
- Absorbing light between 630 and 780 nm i.e. in the zone corresponding to the predominant region of absorption of red light, has the effect of perceiving complementary colors and in particular green.
- the absorbent element can be incorporated into a layer deposited on one of the faces of the glazing; or can be incorporated into the matrix of one of the substrates or advantageously incorporated into the matrix of at least one interlayer lamination sheet.
- the absorbent element may comprise several colorants incorporated at different locations of the glazing, for example a mixture of colorants incorporated in the host matrix and a mixture of colorants incorporated in the lamination insert.
