1. A method of manufacturing a coating or film comprised of a transparent highly elastic, 3-dimensionally cross-linked plastic material, which coating or film may be employed as an external anti-lacerative or self-healing layer of a laminated pane, wherein said coating or film is comprised of at least one surface active agent disposed within its cross-linked structure, wherein the coating or film is formed in advance in known fashion and is treated by placing it in contact with a formulation comprised of said at least one surface active agent, under conditions and for a duration sufficient to permit diffusion of molecules of the surface active agent(s) into at least a part of the interior of the coating or film. 2. The method of claim 1 wherein the formulation is in the liquid state. 3. The method of claim 2 wherein the treatment of the coating or film is carried out by steeping said coating or film in a liquid formulation. 4. The method of claim 1 wherein the treatment is carried out at a temperature between 20° and 120° C. 5. The method of claim 4 said temperature is between 80° and 100° C. 6. The method of claim 1 wherein an elevated pressure on the order of 5 to 15 bar is exerted during the course of the treatment. 7. The method of claim 1 wherein the coating or film is treated when it has already been combined with a support to form a laminated pane. 8. The method of claim 7 wherein the coating or film is preliminarily combined with the support, and is then treated in an autoclave, which treatment serves simultaneously to bring about permanent combination of the laminated pane. 9. The method of claim 8 wherein the treatment is carried out in an autoclave with a liquid under pressure, wherewith the compression liquid is the liquid formulation comprised of the surface active agent(s).
