    Abstract: Method for applying corrosion protection layer on a metallic surface comprises treating the surface with a formulation containing at least one binding agent, a pigment and/or a filler and a corrosion protecting agent, which is at least one thioamide group containing compounds. Method for applying corrosion protection layer on a metallic surface comprises treating the surface with a formulation containing at least one binding agent, a pigment and/or a filler and a corrosion protecting agent, which is at least one thioamide group of formula -C(S)NR 1>R 2> containing compounds such as thioamide compound (D1) of formula R 4> n-R 3>-C(S)NR 1>R 2> or thioamide (D2) with at least two thioamide group. n : 1-5; R 1>, R 2>H or optionally substituted 1-20C alkyl; R 3>(n+1)-valenced 1-30C hydrocarbon; and R 4>functional group. Independent claims are included for: (1) a method for applying an integrated pretreating layer on metallic surface comprising treating the metallic surface with a crosslinkable preparation, containing a binding agent, a crosslinkable component, where the crosslinkable group is bounded with the binding agent and/or additionally a crosslinker is used, a pigment and/or filler, a corrosion protecting agent and optionally a solute, and crosslinking the applied layer, where the amount of the binding agent is 20-70 wt.%, filler contains 20-70 wt.% of at least one inorganic fine particulate fillers with an average particle size of less than 10 mu m, and the corrosion protecting agent contains 0.25-10 wt.% of thioamide group containing compounds, where the wt.% relate to the sum of all components except the solute; (2) a polymer comprising at least two terminally and/or laterally positioned thioamide group of formula -C(S)NR 1>R 2>; (3) integrated pretreating layer on a metallic surface of steel, zinc or its alloy or aluminum or its alloy obtained by the method; (4) metallic surface comprising the integrated pretreating layer; (5) a strip metal from steel containing a coating from zinc or its alloy comprising the surface; (6) a preparation, for applying corrosion protection layer on metallic surface, comprising at least one binding agent, a pigment and/or a filler and a corrosion protecting agent, which is at least one thioamide group of formula -C(S)NR 1>R 2> containing compounds such as thioamide compound (D1) of formula R 4> n-R 3>-C(S)NR 1>R 2> or thioamide (D2) with at least two thioamide group; and (7) a preparation, for applying an integrated pretreating layer on metallic surface, comprising a binding agent, a crosslinkable component, where the crosslinkable group is bounded with the binding agent and/or additionally a crosslinker is used, a pigment and/or filler, a corrosion protecting agent and optionally a solute, where the amount of the binding agent is 20-70 wt.%, filler contains 20-70 wt.% of at least one inorganic fine particulate fillers with an average particle size of less than 10 mu m, and the corrosion protecting agent contains 0.25-10 wt.% of thioamide group containing compounds, where the wt.% relate to the sum of all components except the solute.

    Abstract: The invention relates to a composition for the treatment of metal surfaces and to the deposition of metals or metal alloys on plastics surfaces, comprising a) at least one polymer as component A, composed of an amino-containing polymer (component Aa), at least one aromatic compound (component Ab), and, where appropriate, an aldehyde (component Ac); b) water or another solvent suitable for dissolving, dispersing, suspending or emulsifying the polymer, as component B; c) if desired, surface-active compounds, dispersants, suspension media and/or emulsifiers as component C. The invention further relates to a process for the treatment of a metal surface and also to a process for the deposition of metals or metal alloys on a-plastics surface in which the metal or plastics surface is contacted with a polymer (component A). The invention further relates to the use of polymers (component A) for the treatment of metal surfaces and for the deposition of metals or metal alloys on a plastics surface, and to polymers composed of specific components A'a, Ab and A'c.
