    Abstract: A composition for the surface treatment of metals and for the deposition of metals or metal alloys and plastics surfaces comprises a) at least one polymer as component A, comprising at least one structural unit of the formula (I) where this structural unit may be part of a polymer main chain or may be bound to a polymer main chain via an anchor group, and M is hydrogen or an ammonium or metal cation; b) water or another solvent which is suitable for dissolving, dispersing, suspending or emulsifying the polymer (component A), as component B; c) if required, surface-active compounds, dispersants, suspending media and/or emulsifiers as component C; either d) if required, a salt, an acid or a base based on transition metal cations, transition metal oxoanions, fluorometallates or lanthanoids as component D, and/or e) at least one acid selected from the group consisting of phosphoric acid, sulfuric acid, sulfonic acid, nitric acid, hydrofluoric acid and hydrochloric acid as component E, or a base and/or f) at least one metal oxide and/or metal salt as component F. Furthermore, in a process for the surface treatment of metals and in a process for the deposition of metals or metal alloys on a metal surface or plastics surface, the metal surface or plastics surface is brought into contact with a polymer (component A). Moreover, polymers (component A) are used for the surface treatment of metals and for the deposition of metals or metal alloys on a metal surface or plastics surface.

    Abstract: The invention relates to a method for treating the surfaces of aluminium or aluminium alloys by anodically oxidising the aluminium or aluminium alloys i n an electrolyte, the electrolyte containing 3 to 30 wt. % of an alkane sulfon ic acid. The invention also relates to the use of aluminium or aluminium alloy workpieces produced according to said method, in the building trade, in car or aeroplane construction and in packaging. The invention further relates to an electrolyte composition for the anodic oxidation of aluminium or aluminium alloys, wherein the electrolyte contains 3 to 30 wt. % of an alkane sulfonic acid, as well as the use of an alkane sulfonic acid in a method for the anod ic oxidation of aluminium or aluminium alloys in order to increase the speed of the anodic oxidation and to reduce the required energy consumption for the process.

    Abstract: The invention relates to a method for producing gold-coloured aluminium oxide layers, whereby the oxidised surface of the aluminium or aluminium alloy is coloured in an electrolyte containing an alkane sulfonic acid and a silver alkane sulfonate by means of an electrolytic method. The invention also relates to using of the gold-coloured aluminium or aluminium alloy workpieces produced by said method for decorative purposes. The invention further relates to an electrolyte solution for the gold coloration of the oxidised surface of aluminium or an aluminium alloy by means of an electrolytic method, and the use of an electrolyte containing a silver alkane sulfonate for the gold coloration of aluminium oxide layers in aluminium and aluminium alloys in an electrolytic method.

    Abstract: The invention relates to a method for electrolytically coating metalswith zinc or a zinc alloy. Matt surfaces are obtained by depositing zinc from an electrolyte solution containing a zinc salt selected from zinc sulphate or an alkane sulphate of zinc or mixtures thereof and optionally other metal salts, an acid selected from sulphuric acid or an alkane sulphonic acid or a mixture of both acids and at least one additive for improving surface roughness and for avoiding dendritic edge growth, selected from surface active compounds containing nitrogen which can be ionic or non-ionic, anionic surface active compounds containing nitrogen, and surface active compounds derived from multi-fuctional alcohols with at least three hydroxy groups. The invention also relates to an electrolytic composition for an electrolytically coating of metals with zinc or zinc alloys, in addition to the use of the above-mentioned additives for improving surface roughness and avoiding dentritic edge growth when metals are electrolytically coated with zinc or a zinc alloy in an electrolyte containing alkane sulphonic acid.
