ABSTRACT:
A bath of pH higher than 4 containing more than 1 mole/liter of Zn.sup.++ ions and at least one polyethylene glycol polymer of the general formula R.sup.1 --O(CH.sub.2 --CH.sub.2 --O).sub.n --R.sup.2, in which n.ltoreq.13 and in which the concentration of polymer in the bath is adapted to incorporate in the coat an organic compound having a content by weight greater than 0.1%, expressed as weight of carbon per unit weight of the coat. The bath is adapted to high current densities, and the coat applied on the steel sheet imparts both a leveling effect and an improvement of corrosion resistance.
