PCT No. PCT/EP95/05090 Sec. 371 Date Oct. 6, 1997 Sec. 102(e) Date Oct. 6, 1997 PCT Filed Dec. 22, 1995 PCT Pub. No. WO96/20152 PCT Pub. Date Jul. 4, 1996Salts of aromatic hydroxy compounds are used as brighteners in acidic electroplating baths. Furthermore, acidic electroplating baths for the electrolytic deposition of metallic layers onto shaped articles comprise, as brighteners, at least one novel salt of an aromatic hydroxy compound. Finally, shaped articles are electroplated by a process using the novel acidic electroplating baths.
