Abstract: The use of salts, which are soluble in the aqueous bath in which they are employed, of polymers of the N-vinyl and/or N-allyl forms of nitrogen-containing heterocyclic compounds having 5 or 6 members in the heterocyclic ring system, from 1 to 100 mol-% of these compounds being quaternized with C1- to C12-alkyl groups and/or benzyl groups, as conditioning agents for the pretreatment of nonmetallic surfaces, before they are primed (given a nucleating treatment) for a subsequent chemical metallization. The metal coatings obtained using these conditioning agents are particularly uniform and adhere well.
