Abstract

An aqueous copper plating electrolyte, comprising copper sulphate or fluoborate and sulphuric or fluoboric acid, contains an N-(tetrahydropyranyl -2) amide of a carboxylic or thiocarboxylic acid dissolved in the electrolyte as a primary brightening agent, and as a secondary brightening agent amines of the formula: <FORM:1044308/C6-C7/1> or ammonium ions of the formula: <FORM:1044308/C6-C7/2> where R1 is one of the cyclic radicals of tetrahydropyranyl, tetrahydrofuryl or thiazyl; R2 and R3 is H,alkyl,phenyl, 2-carboxyphenyl,4-hydroxyphenyl, 4-sulphophenyl,p-diphenyl,2-pyridyl,6,8-disulpho -2-naphthyl or the sulphonic acid radicals (CH2)n-SO3H,n being an integer from 0 to 4 and R4 is alkyl. N-propane-w-sulphonic acid may be substituted for H in the amide of the primary agent. Examples of the primary agent are any combination or: N-tetrahydropyranyl-2-(n-propane-w-sulphonic acid)-(thio) acetamide/propionamide/butyramide /benzamide/p-toluamide or -nicotinamide/ picolinamide/(thio) urea or N'-acetyl(thio)urea/carbethoxy (thio)urea/formyl(thio)urea/cyanothiourea/ carboxy(thio)urea/phenylsulphonyl(thio)-urea/nitro (thio)urea/allylthio-urea/phenylthiourea.
