Abstract
Abstract Flowable colored compositions containing alkoxylated fatty acid alkanolamides as viscosity stabilizers. The compositions preferably contain up to about 20% by weight of the reaction products of ethylene oxide with monoethanolamides of higher fatty acids and are particularly suitable for the preparation of hectographic papers.
