Abstract

Procedure for the preparation of a galvanic acid zinc bath, which does not contain any organic complex forming agent, with a content of known gloss forming agents for the deposition of zinc coatings from bright to very bright, characterized in that products are mixed polycondensation of formaldehyde with naphthalenesulfonic acids in amounts of 0.5 to 100g/liter, preferably 2 to 15g/liter, with an aqueous solution containing a zinc salt, conductive salts and possibly known gloss-forming agents, as well as boric acid and/or aromatic carboxylic acids or salts thereof.
