description Aqueous polyacrylate dispersions comprising hydrophobic co-solvents are provided. The dispersions are prepared from copolymers P) which are comprised of I) a hydroxy-functional, hydrophobic polymer containing as structural monomers Ia) (meth)acrylic acid esters having from C1- to C18-hydrocarbon radicals in the alcohol part and/or vinyl aromatic compounds and/or vinyl esters and Ib) hydroxy-functional monomers; and II) a hydroxy-functional, hydrophilic polymer containing as structural components IIa) (meth)acrylic acid esters having from C1- to C18-hydrocarbon radicals in the alcohol part and/or vinyl aromatic compounds and/or vinyl esters, IIb) hydroxy-functional monomers and IIc) acid-functional monomers, and as solvents C) one or more solvents selected from the group consisting of hydrophobic, water-immiscible hydrocarbons having an initial boiling point of from 170° C. to 250° C. and a dry point of from 200° C. to 280° C., to a process for their preparation and to their use as binders for the production of blister-free coatings.
