    Abstract: Mixture (I) comprises at least a highly concentrated synthetic thickener (A) (1-99 wt.%) with an active substance based on acrylic acid containing polymers in water-in-oil emulsion; and at least a low concentrated synthetic thickener (B) (1-99 wt.%) with an active substance containing a polymer (containing building blocks of e.g. at least ethylenic unsaturated carboxylic acid (a) with free acid functional groups). Mixture (I) comprises at least a highly concentrated synthetic thickener (A) (1-99 wt.%) with an active substance (35-100 wt.%) based on acrylic acid containing polymers in water-in-oil emulsion; and at least a low concentrated synthetic thickener (B) (1-99 wt.%) with an active substance (0.1-34 wt.%) containing a polymer (containing building blocks of at least a ethylenic unsaturated carboxylic acid (a) (10-80 mol.%) with free acid functional groups; at least a ethylenic unsaturated carboxylic acid (b) (20-90 mol.%), whose acid functionalities as ammonium or metal salts, where the sum of (a) and (b) results in 100 mol.%; and at least ethylenic unsaturated diagonal cross-linker (c)), where the sum of (A) and (B) results in 100 wt.% in a water-in-oil emulsion. Independent claims are also included for: (1) printing and coating pastes, coloring and equipment fleets, comprising aqueous dispersion of polymers (C) (0.1-99.9 wt.%) containing acrylate-, butadiene- and/or urethane, mixtures of synthetic thickeners (D) (0.1-99.9 wt.%), additives (E) (0-99.9 wt.%) such as antifoaming agents, emulsifying agents, natural thickeners or their mixtures, cross-linkers, improved fasteners, softeners and colorants, and additional water (F) (0-99.9 wt.%), where the sum of (C)-(F) amounts to 100 wt.%; and (2) printing paste comprising a mixture of synthetic thickeners (G) (0.1-99.9 wt.%), additives (H) (0.1-99.9 wt.%) such as antifoaming agents, emulsifying agents, film formers and coloring materials, additional water (I) (0-99.9 wt.%), where the sum of (G)-(I) results in 100 wt.%.
