Abstract
Method for pretreating a plastic substrate prior to metallization thereof by electroless metal deposition by applying a brush discharge thereto, the current density of which is higher than 0.5 mA/cm.sup.2, the tension of which being less than the breakdown tension of the substrate and the total charge of energy applied being no higher than 20mC/cm.sup.2 ; the treatment comprising plural short spaced exposures of said substrate to said discharge. Various masking means are employed to provide selectively treated and untreated portions on the substrate.
