Abstract

Et nytt elektrolytt-tilsetnlngsnlddel for et svovelsurt, tinn(II)holdig farvebad for vekselstrømfarving av anodlserte alumlnluraoverflater bestående av en synerglstisk blanding av minst en antloksydant med en av de generelle formler (I) til (IV) (I) (II) (IV) der R1 og R2 betyr hydrogen, alkyl, aryl, alkylaryl, tUkylaryleulfonsyre, alkylsulfonsyre, med l til 22 C- atorner, samt deres alkallmetallsal ter, og der R3 betyr en eller flere hydrogen- og/eller alkyl-, aryl-, alkylarylrester med l til 22 C-atomer, hvorved minst en av restene R1, F2 og R3 er forskjellig fra hydrogen, og/eller 2,7-dlsulfo-4-hydroksy-naftalin, samt minst en sprednlngsforbedrer med den generelle formel (V) der R1 til R5 betyr hydrogen-, hydroksyl-, karboksyl- og/eller sulfonsyrerester. (V) Videre beskrives en fremgangsmåte for vekselstromfarvlng av anodlserte aluninlimi- overflater under anvendelse av dette elektrolytt-tllsetnlngsralddel.A new electrolyte additive portion for a sulfuric acid, tin (II) -containing dye for alternating anodized alumina surface dye consisting of a synergistic mixture of at least one antioxidant with one of the general formulas (I) to (IV) (I) (II) (IV) ) wherein R 1 and R 2 represent hydrogen, alkyl, aryl, alkylaryl, alkylaryleulfonic acid, alkylsulfonic acid, having 1 to 22 C atoms, and their alkali metal salts, and where R3 represents one or more hydrogen and / or alkyl, aryl, alkylaryl residues with 1 to 22 C atoms, wherein at least one of the residues R1, F2 and R3 is different from hydrogen, and / or 2,7-dlsulfo-4-hydroxy-naphthalene, and at least one scattering enhancer of the general formula (V) wherein R 1 to R 5 represent hydrogen, hydroxyl, carboxylic and / or sulfonic acid residues. (V) Further, a method of alternating staining of anodized aluminine surfaces is described using this electrolyte-settling portion.
