Abstract

Dry products in flake or granulate form suitable as a paste base may be obtained by drying a mixture, containing approximately 30 to 80% by weight of water, of from PA1 (a) 30 to 95% by weight of carboxymethylated and/or alkoxylated starch, PA1 (b) 3 to 40% by weight of a cellulose ether, and PA1 (c) 2 to 40% by weight of a water-dispersible polymer or water-soluble polymer, and PA1 (d) optionally, conventional additives, such as preservatives, wetting agents, fillers and the like, in a thin layer on a surface heated to 80.degree. to 200.degree. C. The dry products obtained do not undergo physical separation and are readily dispersible or self-dispersible in water.
