INVENTOR: CIPARISSO, DELIOINVENTION: METHOD FOR THE PRELIMINARY TREATMENT OFTRANSPARENT PLASTIC SUBSTRATES INTENDEDTO BE COATED IN VACUUM.ABSTRACT OF THE DISCLOSUREThe vacuum apparatus comprises a vacuum vessel, whichis connectable to a vacuum pump and a gas source and whichserves the purpose of receiving the sample holder for the sub-strate and of which the interior is permeable by high-frequencyoscillations between the electrodes of a high-frequency genera-tor. As a result of such a plasma treatment of the substrate,the surface thereof is changed to such a degree that the sub-sequent layer can be applied with an adhesive strength notreached before.
