摘要：
A dispersion which is free of binders and which contains titanium dioxide and at least one water-soluble poly- carboxylate ether, where - the titanium dioxide has a BET surface area of 20 to 400 m2/g, the water-soluble polycarboxylate ether is a copolymer based on at least one oxyalkylene glycol compound and at least one unsaturated monocarboxylic acid derivative or dicarboxylic acid derivative, the dispersion has a content of titanium dioxide of 5 to 50% by weight, based on the total amount of the dispersion.
