The process consists in coating the inside surface of said windscreen with a liquid composition, which, after curing with ultra violet and infrared rays, forms a high strength, hard and flexible film. The coating is prepared so that, during the curing process, a polyurethane of aliphatic polycaprolactone is formed as an interpenetrating network system, with a partially cross-linked vinylacrylic copolymer, the whole being formed in the presence of a controlled quantity of a polyester urethane acrylate prepolymer.
