Abstract (en)

[origin: WO2022112242A1] Disclosed is a composite pane (100) comprising an outer pane (1) having an outer surface (I) and an inner surface (II), an inner pane (2) having an outer surface (III) and an inner surface (IV), and a thermoplastic intermediate layer (3) that connects the inner surface (II) of the outer pane (1) to the outer surface (III) of the inner pane (2), wherein the composite pane (100) has at least one sun shading coating (4) between the outer pane (1) and the inner pane (2), said sun shading coating (4) comprising, from the inner pane (2) in the direction of the outer pane (1), a sequence of layers consisting of - a first dielectric module (M1), - a first silver layer (Ag1), - a second dielectric module (M2), - a second silver layer (Ag2), - a third dielectric module (M3), - a third silver layer (Ag3), - a fourth dielectric module (M4), the silver layers (Ag1, Ag2, Ag3) having, relative to one another, a geometrical layer thickness of Ag2 > Ag1 > Ag3, and the silver layers of the sun shading coating (Ag1, Ag2, Ag3) having a relative geometrical layer thickness of 1.0 < Ag1/Ag3 and 1.2 < Ag2/Ag3 <2.
