Zusammenfassung:	Production of a safety pane comprising a sheet of glass and a polyurethane-based layer having energy-absorbent properties. The polyurethane-based layer having energy-absorbent properties is formed directly on the sheet of glass by reactive spraying of a reactive mixture of an isocyanate component having a viscosity under 5000 centipoises at 40 degrees C. and a polyalcohol component, with the isocyanate component containing at least one aliphatic or cycloaliphatic diisocyanate, or a prepolymer of these isocyanates, with the polyalcohol component containing at least one long difunctional polyalcohol having a molecular mass between 500 and 4000 and at least one short diol as a chain extending agent.
