1. A composite pane, comprising 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 solar protection coating reflects or absorbs rays outside the visible spectrum of solar radiation,
a thermal-radiation-reflecting coating is applied directly to the interior-side surface of the inner pane,
the thermoplastic intermediate layer has, in at least one region, an opaque layer that is devoid of glass-forming oxide or glass frit, and
at least a portion of the opaque layer is provided in contact with the solar protection coating such that the solar protection coating is arranged between the interior-side surface of the outer pane and said portion of the opaque layer.
