Zusammenfassung:Water-based compositions which are usable in the formulation of inks, particularly for flexographic printing, containing an acrylic copolymer and a resin, rosin or rosin derivative, in the absence of any protein component. Rosin esters may also be used. a proportion of the acidity of the resin or resin derivative can be neutralised by a base such as ethanolamine to form a soap which disperses the rosin. The copolymer preferably has a glass transition temperature of 0 DEG C or lower.
