A nonaqueous coating material composition and coatings thereof are provided. The composition contains an oligomeric and/or polymeric compound (A) having at least two hydroxyl groups, an oligomeric and/or polymeric compound (B) having at least two alkylidene-1,3-dioxolan-2-one groups of formula (I'), and a catalyst (D) where # stands for the attachment to the polymer backbone and

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.

Aqueous primary dispersions and coating agents, methods for producing them and their use
