A method for the inhibition of electrochemical metallization on an isolated surface of a frame area, said method comprising the step of contacting the isolated surface of the frame area with an aqueous inhibition composition comprising an inhibiting agent which is at minus one according to formula I R2N-C (S) Y (I) in which R is independently from each other H or a branched or unbranched C1, C13 alkyl, alkenyl or aryl group and Y is XR1, NR2 N (H) NR3 2 where X is O or S, and R1, R2, R3 are independently from each other H, an alkali metal or a branched or unbranched C1, C13 alkyl, alkenyl or aryl group, wherein the isolation in the Isolated areas of the frame is a polymer of the group consisting of polymers of PVC, polycarbonate, polyamide, polyurethane, PTFE, ECTFE, partially halogenated, especially partially fluorinated. |
