Temperatures from 20 ° to 95 ° C., preferably from 25 ° to 60 ° C. and residence times from 2 seconds to 10 minutes, preferably from 10 seconds to 3 minutes, are found to be the most favorable for practical use. An increase in the bath temperature favors the chemisorption of the polymer-metal complexes on the substrate. This makes it possible to reduce the dwell times considerably, particularly in the case of continuous strip treatment.
  • the immersion treatment is then expediently followed by a rinsing step with water, primarily with tap water.
  • This rinsing process can serve on the one hand to remove excess treatment solution from the carrier, on the other hand the acidic treatment solution on the carrier becomes so strong by dilution with water shifted from the neutral point that the dissolved complexes can precipitate in the pores of the substrate and are thus firmly fixed on the support.

  • the complex-like reaction products described above are formed on the substrate during the treatment.
  • This variant of the process can also be used to apply the complex-like reaction products of trivalent metal ions which are difficult to dissolve in strongly acidic media to the substrate.
