Abstract

The invention relates to aqueous dispersions for paper sizing containing sizing agent and one or more emulsifiers, the sizing agent having a molecular weight of < 2000 g/mol and being predominantly in the form of particles with a particle diameter of less than 1 prm, characterised in that 50 % of the sizing agent particles have a particle diameter (D50) of less than 600 nm and 90 % of the sizing agent particles have a particle diameter (D90) of less than 800 nm, the difference between D90 and D50 ranging from 50 nm to 500 nm. The invention also relates to a method for producing the dispersions.
