The invention relates to aqueous dispersions comprising multistage-prepared polymers, and also to coating material compositions comprising them, preparable by multistage polymerization of olefinically unsaturated monomers, using an emulsifier and a water-soluble initiator, under conditions of starved feed polymerization, and using particular monomer mixtures in the individual stages. The invention also relates to a pigmented aqueous basecoat material comprising the aqueous dispersion of the invention, to the use of the aqueous dispersion of the invention in aqueous basecoat materials for improving adhesion, to a process for producing a multicoat paint system on a substrate, and to a multicoat paint system produced in accordance with the stated process.

Aqueous dispersions containing multistage produced polymers and coating agent compositions containing the same

The present invention relates to a nonaqueous coating material composition comprising at least one compound (A) having at least two amino groups and at least one oligomeric and/or polymeric compound (B) having at least two alkylidene-1,3-dioxolan-2-one groups. Compound (B) is obtained using at least one monomer (B1) of formula (I) where R-R, A, X, Z, and Y are as set forth in the specification and at least two different comonomers (B2) and (B3) which are each different from the monomer (B1). The present invention further provides the coatings produced from these coating material compositions, and also the use thereof.

Coating material compositions and low-temperature-curable coatings produced therefrom, and use thereof

An aqueous coating material, substantially or completely free from volatile organic compounds and preparable by mixing with one another (A) at least one aqueous primary dispersion comprising dispersed and/or emulsified, solid and/or liquid polymer particles and/or dispersed solid core/shell particles with a diameter &#x2266;500 nm, preparable by free-radical microemulsion or miniemulsion polymerization of at least one olefinically unsaturated monomer in the presence of at least one hydrophobic additive, and (B) at least one secondary aqueous polyurethane dispersion comprising at least one polyurethane and at least one light stabilizer selected from the group of the regenerable free-radical scavengers, a process for preparing it and its use.

Aqueous coating substance that is substantially or completely free of volatile organic substances, method for producing the same and the use thereof

Aqueous primary dispersion, substantially or entirely free of volatile organic compounds, and comprising dispersed and/or emulsified, solid and/or liquid polymer particles and/or dispersed solid core/shell particles with a particle diameter&#x2266;500 nm, preparable by free-radical micro- or miniemulsion polymerization of at least one olefinically unsaturated monomer in the presence of at least one hydrophobic additive and of at least one oligomeric polyester with a number-average molecular weight of from 150 to 1 500 daltons, a hydroxyl number of from 100 to 1 000 mg KOH/g, and an acid number&#x3c;20 mg KOH/g and also a process for preparing it and its use as a coating material, adhesive or sealing compound or to prepare a coating material, an adhesive or a sealing compound.

Aqueous primary dispersion, substantially or completely devoid of volatile organic substances, method for the production thereof and use of the same

Aqueous primary dispersions and coating materials comprising dispersed and/or emulsified, solid and/or liquid polymer particles and/or dispersed solid core-shell particles having a diameter&#x2266;500 nm, preparable by free-radical microemulsion or miniemulsion polymerization of at least one olefinically unsaturated monomer (A) in the presence of at least one hydrophobic crosslinking agent for the (co)polymer resulting from the monomer or monomers (A), wherein said monomer or monomers (A) is or are dispersed prior to (co)polymerization in an aqueous dispersion of said crosslinking agent or agents; processes for preparing them, and their use.
