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