COMPOSITION, USE OF A CELLULOSE ETHER AS THICKENING AGENT AND PRODUCTION OF A COATED CELLULOSE-BASED TWO-DIMENSIONAL PRODUCT

摘要

The present invention relates to an aqueous composition for coating, such as sizing or application of a layer of a coating slip, of cellulose-based two-dimensional products. The composition has improved properties at increased temperatures and at high shear rates. These properties are achieved by using as tickening agent a cellulose ether which is substituted with hydroxyalkyl groups, such as hydroxyethyl and hydroxypropyl, and alkyl groups having 1-3 carbon atoms, and which has a cloud point in the range from 35 .degree.C to 80 .degree.C.
