A polyurethane coating layer, with self-repairing properties, for panes made of glass and/or plastic materials, which are exposed to atmospheric agents. The coating layer according to the invention is formed from a reactive mixture of a trifunctional isocyanate component such as the biurets or isocyanurates of 1,6 hexamethylenediisocyanate, having a content of about 15 to 25% by weight of NCO radicals and a polyalcohol component chosen from the plurifunctional polyester polyalcohols having about a 3 to 12% by weight content of OH radicals.
