Abstract
The invention relates to an almost opaque decorative glass panel comprising a substrate made of a vitreous material bearing a multilayer stack including at least one light-absorbing functional layer and transparent dielectric coatings such that the light-absorbing functional layer is enclosed between dielectric coatings. The light-absorbing functional layer has a geometric thickness comprised between 25 and 140 nm, and an extinction coefficient k of at least 1.8. The multilayer stack in addition comprises at least one attenuating layer placed between the substrate and the light-absorbing functional layer, having a thickness comprised between 1 and 50 nm, having a refractive index n higher than 1 and an extinction coefficient k of at least 0.5. Furthermore, a transparent dielectric coating the optical thickness of which is comprised between 30 and 160 nm, and the refractive index n of which is higher than 1.5, is placed adjacent to the attenuating layer on the side opposite the light-absorbing functional layer. The invention provides a decorative panel offering a pleasant aesthetic effect.
