    摘要: The invention relates to a process for antistatic treatment or pretreatment for subsequent surface-coating of materials based on polyamides, polyimides or polyamideimides, where the molded articles of the material are treated with a solution of salt mixtures comprising(a) halides of elements of main groups 1 and/or 2 of the periodic system, in particular CaCl.sub.2, MgCl.sub.2, LiCl, NaCl and/or KCl and(b)(1) salts of weak inorganic bases with strong inorganic acids, in particular AlCl.sub.3, FeCl.sub.3, TiCl.sub.4, SbCl.sub.5, CaCl.sub.2, FeCl.sub.2, CuCl.sub.2, ZnCl.sub.2 and/or MoCl.sub.5(2) and/or the chelate complexes of (b1) with Schiff bases, amines, carboxylic acids, diketones, .alpha.,.beta.-unsaturated ketones and phosphines,(c) in a non-corrosive, organic swelling agent or solvent for the materials mentioned, where appropriate with the addition of water, preferably in an alcohol, at temperatures up to the boiling point of the solvents, preferably at temperatures of from -15.degree. C. to +60.degree. C., for from 0.5 to 30 minutes, and the molded articles are washed with water or solvents and subsequently dried.Antistatic molded articles treated by the process and molded articles pretreated for subsequent surface-coating, and the use thereof, are furthermore claimed.
