Abstract

An electrically conductive surface layer is produced on moldings consisting of plastics which are soluble or swellable in organic solvents, the conductivity of the said layer being based on a system, incorporated therein, of PA1 organic electron acceptors (I) on the one hand and PA1 organic electron donors (II), iodides (III) or a mixture of (II) and (III) as electron donors, on the other hand, by a process in which the moldings are treated with organic solutions of these components. The products have a surface resistance of from 10.sup.8 to 10.sup.2 ohm and have the advantage that the remaining properties of the moldings are virtually unaffected by the agents (I) to (III).
