Abstract

A composite pane, includes a laminated stacking sequence composed of an outer pane having an exterior-side surface and an interior-side surface, an inner pane having an exterior-side surface and an interior-side surface, and at least one thermoplastic intermediate layer that joins the interior-side surface of the outer pane to the exterior-side surface of the inner pane, wherein a solar protection coating is applied directly to the interior-side surface of the outer pane, which coating substantially reflects or absorbs rays outside the visible spectrum of solar radiation, in particular infrared rays, a thermal-radiation-reflecting coating is applied directly to the interior-side surface of the inner pane, and the thermoplastic intermediate layer has a printed opaque layer in at least one region.
