Abstract: The compositions of the present invention are preferably polyurethane-free, aqueous primer coatings for print substrates comprising a dispersion of an at least partially neutralized copolymer of ethylene and (meth)acrylic acid and a dispersion of an at least partially neutralized copolymer that is obtained by emulsion copolymerization of at least methyl (meth)acrylate and one or more alkenyl phosphate esters and further optionally one or more comonomers chosen from (meth)acrylic acid and diacetone (meth)acrylamide

Abstract: Disclosed is a method for the production of thermoplastic polymer dispersions, using a reaction vessel with a first volume and a secondary volume, wherein a first stirrer is located and operative in said first volume and a secondary stirrer is located and operative in said secondary volume, wherein the first volume is at least 20 times larger than the secondary volume, wherein the stirrers in both volumes are able to handle viscosities above of or equal to 1000 mpas, including the steps of a.) loading the first volume of the vessel with an initial amount of polymer and optionally water and optionally alkaline; b.) heating the vessel externally to a target process temperature in the range of 80-300° C.; c.) operating the first stirrer in the first volume for at least half an hour at a speed of in the range of 10-100 rpm; d.) addition of water and optionally alkaline to the first volume; e.
