摘要

The agent for preventing the flooding of coloured pigments from polymer emulsion (dispersion) paints, polymer renders or distempers that contain cellulose ether is based on a block polymer of a di- or polyamine and added alkylene oxide units. The block polymer conforms to the formula II. The substituents in formula II are as defined in Claim 1. The agent is used for aqueous binder-containing paints or renders that contain cellulose ether and are to be coloured or are already coloured and are or would be white without the addition of coloured pigment.
