    Abstract: A composition for the treatment of metal surfaces comprises 50-99.9 wt.% (meth)acrylic acid or its salts, 0.1-50 wt.% of a carboxylate containing monomer or corresponding salts, anhydrides or esters and/or 0.1-50 wt.% monomers containing phosphoric and/or phosphoric acid groups or their salts, 0-30 wt.% of other compatible monomers and water or another solvent suitable for the dispersion, suspension or emulsification of monomers. A composition (I) for the treatment of metal surfaces comprises: (a) 50-99.9 wt.% (meth)acrylic acid or its salts, 0.1-50 wt.% of a carboxylate containing monomer of formula (1) or corresponding salts, anhydrides or esters and/or 0.1-50 wt.% monomers containing phosphoric and/or phosphonic acid groups or their salts, 0-30 wt.% of other compatible monomers; (b) water or another solvent suitable for the dispersion, suspension or emulsification of (A) and optionally; (c) other surface active agents, dispersing agents, suspending agents and/or emulsifiers. [Structure 1, p46] (1) n : 0-10; R 1>, R 2>,R 3>H, 1-18C alkyl, 3-6C cycloalkyl, 2-18C alkenyl, 3-6C cycloalkenyl, 6-12C aryl optionally substituted by alkyl or aryl whereby R 1>-R 3> are optionally substituted by a carboxyl group; R 4>,R 5>H, 1-18C alkyl, 3-6C cycloalkyl, 2-18C alkenyl, 3-6C cycloalkenyl, 6-12C aryl optionally substituted by alkyl or aryl Independent claims are included for: (1) a passivating layer on a metal surface prepared by contacting the metal surface with the component (A); (2) the resulting passivated metal surface and: (3) a structure prepared by application of further coating layers onto the passivated metal surface.

    Abstract: A process for preparing copolymers which comprises copolymerizing (A) at least one ethylenically unsaturated dicarboxylic anhydride derived from at least one dicarboxylic acid having 4 to 8 carbon atoms, (B) at least one vinylaromatic compound, and (C) optionally at least one non-(A) ethylenically unsaturated comonomer containing at least one heteroatom, (D) reacting the copolymer with at least one compound of the formula I a or I b where A 1 is C 2 -C 20 alkylene, identical or different, R 1 is C 1 -C 30 alkyl, linear or branched, and n is an integer from 1 to 200, hydrolyzing the product with water or an aqueous alkaline solution, and subsequent to hydrolysis adding further free-radical initiator.

    Abstract: A solid pigment preparation contains by wt. (a) a pigment (60-95%); (b) a water-soluble anionic surfactant (5-40%) which is a polymer of an ethylenically unsaturated mono- and/or di-carboxylic acid optionally copolymerized with an acid function-free vinyl monomer, the alkoxylation product of such a (co)polymer or a salt of the (co)polymer or its alkoxylation product; and (c) a polyether-based nonionic surfactant (0-20%). An Independent claim is also included for production of the pigment preparation by wet comminuting pigment (A) in a suspension containing at least a part of (B) and optionally also component (C) and then optionally adding any remainder of (B) and/or (C) and drying the mixture.

    Abstract: The present invention relates to a substantially chromium-free process for passivating metallic surfaces of Zn, Zn alloys, Al or Al alloys by treating the surface with an acidic aqueous formulation which comprises at least one substantially noncrosslinked, water-soluble polymer or copolymer containing at least 50% by weight of (meth)acrylic acid units and comprises water or an aqueous solvent mixture comprising at least 50% by weight of water, and by further treating the surface with at least one water-soluble crosslinker comprising at least 2 crosslinking groups selected from the group consisting of azirane, oxirane, and thiirane groups. The invention further relates to passivating layers obtainable by means of the process and to a formulation suitable for this process.
