Abstract

873,753. Electrodeposition of bright copper. RIEDEL, A., and BACHMANN, F., [trading as RIEDEL & CO.]. Sept. 3, 1957 [March 16, 1957; June 14, 1957], No. 27741/57. Class 41. Bright level electrolytic copper deposits are obtained from acid baths to which are added as brightening agents dithiocarbamic acid derivatives having one or more groups or heterocyclic nitrogen compounds in which one or more of the hydrogen atoms linked to carbon atoms are replaced by the radical -S-(CH2)n-X where X is -OH, -COOH, or a water-solubilizing group other than -SO3H and n is 1 to 10; and as levelling agents water-soluble condensation products of thiourea and formaldehyde where n is 1 to 12, or condensation products of thiourea with formaldehyde and a compound with not less than two -NH2 groups of formula where R is benzene, naphthalene, diphenyl, anthracene, phenanthrene, pyrene, triazine, or other heterocyclic, aliphatic or cycloaliphatic residue and n is 1 to 10. The compound having at least two -NH2 groups may be urea; guanidine; phenylenediamines; 2 : 4<1>-diaminodiphenyl; melamine; the 4 : 4<1>-diamino derivatives of azobenzene, diphenylamine or diphenylurea; 4 : 4<1> - diaminostilbene benzidene, naphthalene diamines and their disulphonic acids; o-dianisidine; parafuchsin, or congo red. Brighteners specifically mentioned are N : N - diethyl - dithiocarbamic acid - S - propyl ester-# carboxylic acid, pyrazine-3 : 6- bis-thioglycolic acid, and pyrazine-3 : 6-di- (mercapto-#-hydroxypropane). An alkyl polyglycol wetting agent, e.g. an alkylphenol polyglycol ether, may also be included in the bath.
