The invention relates to an aqueous primary dispersion, substantially or completely devoid of volatile organic substances, containing dispersed and/or emulsified solid and/or liquid polymer particles and/or dispersed solid core-shell particles with a particle diameter </= 500 nm. Said dispersion is obtained by the radical micro- or mini-emulsion polymerisation of at least one olefinically unsaturated monomer, in the presence of at least one hydrophobic additive and at least one oligomeric polyester with a number average molecular weight of between 150 and 1,500 dalton, a hydroxyl value of between 100 and 1,000 mg KOH/g and an acid value < 20 mg KOH/g. The invention also relates to a method for the production of said dispersion and to the use thereof as a coating substance, adhesive and sealant or for producing a coating substance, adhesive or sealant. |
