Abstract: The invention concerns aqueous secondary polymer dispersions based on special acrylate building blocks, a process for their production and their use as binders for the production of blister-free coatings.

Abstract: 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.

Abstract: The invention relates to aqueous polyester-polyacrylate dispersions based on copolymers, to a process for their preparation, and to aqueous coating compositions based thereon and the use thereof as lacquers. The dispersions are prepared from a polyester component A) that comprises the reaction product of A1) one or more saturated, aliphatic and/or aromatic di-, tri- or tetra-carboxylic acids or their anhydrides, and A2)one ore more diols and/or polyols, and a polyacrylate component B) that comprises the reaction product of B1) one or more OH-group-free (meth)acrylic acid esters and/or vinyl aromatic compounds, B2) one or more hydroxy-functional vinyl monomers or hydroxy-functional (meth)acrylic acid esters, and B3) one or more acid-group-containing monomers capable of free-radical copolymerisation, herein te polyester component A) has a hydroxyl number of from 180 to 300 mg KOH/g substance and an acid number of from 0.
