Large surface application of dielectric reflection decreasing scratch resistant layer system useful for synthetic plastic camera lenses and CD players and autoradio displays involves removal (sic) of layers

摘要

Large surface application of a dielectric reflection decreasing scratch resistant layer system comprising an alternating system of thicker low refractive and thinner high refractive layers onto the surface side of a thermoplastic synthetic resin substrate. After a plasma-magnetron based substrate treatment the low refractive layer is removed (sic) with the aid of reactive magnetron sputtering at a higher sputtering rate and the high reactive layers at a lower sputtering rate. An independent claim is included for a device for application of the layers as described above.
