Claim:
A preparation for applying a corrosion control coat to a metallic surface, comprising the following components: (A) 15% to 70% by weight of at least one binder system (A) curable under atmospheric conditions, (B) 0.1% to 40% by weight of at least one polymeric corrosion preventative, (C) 5% to 83.9% by weight of at least one solvent, (D) 1% to 70% by weight of at least one component (D) selected from the group consisting of finely divided fillers, pigments and dyes, the amounts each being based on the total amount of the preparation, wherein the at least one binder system is selected from the group consisting of aqueous or predominantly aqueous dispersions of polyacrylates and styrene-acrylate copolymers (A1), styrene-alkadiene polymers (A2), polyurethanes (A3), alkyd resins (A4), and combinations thereof, wherein the corrosion preventative is at least one copolymer (B) synthesized from the following monomeric structural units: (b1) 70 to 30 mol % of at least one monoethylenically unsaturated hydrocarbon (b1a) having 9 to 27 C atoms and, optionally, at least one monomer (b1b) selected from the group consisting of monoethylenically unsaturated hydrocarbons (b1b′), modified with functional groups X 1 , and vinyl ethers (b1b″), wherein functional group X 1 is selected from the from the group consisting of —Si(OR 5 ) 5 —OR 6 , —SR 6 , —NR 6 2 , —NH(C═O)R 6 , COOR 6 , —(C═O)R 6 , —COCH 2 COOR 6 , —(C═NR 6 )R 6 , —(C═N—NR 6 2 )R 6 , —(C═N—NR 6 —(C═O)—NR 6 2 )R 6 , —(C═N—OR 6 )R 6 , —O—(C═O)NR 6 , —NR 6 (C═O)NR 6 2 , —NR 6 (C═NR 6 )NR 6 , —CSNR 6 2 , —CN, —PO 2 R 6 2 , —PO 3 R 6 2 , and —OPO 3 R 6 2 , R 5 ═C 1 to C 6 alkyl; R 6 =independently at each occurrence H, C 1 to C 6 alkyl, aryl, alkali(ne earth) metal salt) or —SO 3 H; (b2) 30 to 70 mol % of at least one monoethylenically unsaturated dicarboxylic acid having 4 to 8 C atoms and/or its anhydride (b2a) and/or derivatives (b2b) thereof, the derivatives (b2b) being esters of the dicarboxylic acid with alcohols of the general formula HO—R 1 —X 2 n (I) and/or amides or imides with ammonia and/or amines of the general formula HR 2 N—R 1 —X 2 n (II), and the abbreviations having the following definition: R 1 : (n+1)-valent hydrocarbon group having 1 to 40 C atoms, in which nonadjacent C atoms may also be substituted by O and/or N, R 2 : H, C 1 to C 10 hydrocarbon group or —(R 1 —X 2 n ) n: 1, 2 or 3 X 2 : a functional group selected from the group consisting of —Si(OR 3 ) 3 , —OR 4 , —SR 4 , —COOR 4 , —(C═O)R 4 , —COCH 2 COOR 4 , —CSNH 2 , —CN, —PO 2 R 4 2 , —PO 3 R 4 2 , —OPO 3 R 4 2 , and —SO 3 H; R 3 : C 1 to C 6 alkyl; R 4 : H, C 1 to C 6 alkyl, aryl: and also (b3) 0 to 10 mol % of other ethylenically unsaturated monomers, different from (b1) and (b2) but copolymerizable with (b1) and (b2), the amounts each being based on the total amount of all the monomer units in the copolymer.
