Document Type and Number:
WIPO Patent Application WO/2021/151373
Kind Code:
A1
Abstract:
The invention relates to a facade element (1) comprising a coloring transparent or semi-transparent first pane (2) and a mechanically supporting transparent second pane (3) which are firmly connected to one another by an intermediate layer (13), wherein the first pane (2) has a front surface (4) arranged on the light incidence side and an opposite back surface (5), wherein at least one surface (4, 5), selected from the front and back surfaces, has at least one structured region (8, 8'), wherein at least one optical interference layer (9, 9') is arranged on at least one surface (4, 5), selected from the front and back surfaces, for reflecting light within a predetermined wavelength range, wherein the at least one structured region (8, 8') has the following features: - perpendicular to the plane of the first pane (2), a height profile comprising peaks and valleys, wherein an average height difference between the peaks and valleys is at least 2μm, - at least 50%of the structured region is composed of segments which are inclined with respect to the plane of the first pane (2), wherein, with respect to the plane of the first pane (2), at least 20%of the segments have an angle of inclination in the range from greater than 0° to a maximum of 15° and at least 30%of the segments have an angle of inclination in the range from greaterthan 15° to a maximum of 45°, wherein - the segments are each planar and have a segment area of at least 1μm 2, wherein the segments each have an average roughness of less than 15%of a layer thickness of the at least one optical interference layer.
