Abstract

Aqueous alkaline cyanide-free baths comprise (I) a zinc ion source and if appropriate a source of further metal ions, (II) at least one cationic polycondensation product obtainable by condensation of (i) a noncyclic amine (A1) prepared by reaction of mono(N,N-dialkylaminoalkyl)amine (A1a) with a bifunctional compound (A1b) selected from the group consisting of urea, thiourea, dialkyl carbonates, aliphatic and aromatic dicarboxylic acids and aliphatic and aromatic diisocyanates, in a molar ratio of (A1a) to (A1b) in the range from 1.2:1 to 2.1:1, or (ii) a mixture (A2) of at least one noncyclic amine (A1) and at least one cyclic amine (A3) in a molar ratio of (A1) to (A3) in the range from 10:1 to 1:10 with at least one bifunctional compound (B) selected from the group of the halomethyloxiranes and bisepoxides and, when at least one cyclic amine (A3) is condensed, the alkylene dihalides and dihaloalkyl ethers in a molar ratio of (B) to (A1) or (B) to (A2) in the range from 0.6:1 to 1.3:1.
