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

An aqueous coating material that is substantially or completely free from volatile organic compounds comprising a mixture of:

• (A) from 50 to 95% by weight of at least one aqueous primary dispersion comprising a polymer having a diameter ≦500 nm comprising a controlled free-radical microemulsion or miniemulsion polymerization product of at least one olefinically unsaturated monomer in the presence of at least one hydrophobic additive, wherein the polymer is at least one of a dispersed solid polymer particle, an emulsified solid polymer particle, a dispersed liquid polymer particle, an emulsified liquid polymer particle, and a dispersed solid core-shell particle, and
• (B) from 5 to 50% by weight of at least one secondary aqueous polyurethane dispersion comprising at least one polyurethane and at least one light stabilizer that is at least one of a regenerable free-radical scavenger,
• all percents by weight based on the aqueous coating material.
