Anti-settling agents for pigmented aqueous lacquer and process for the manufacture of said agents

摘要

Water-dispersible (including water-soluble) salts of water- soluble amines with the anionic products formed by reacting at 200 C. to 250 C. a substantially neutral ester of a C.sub.14-20 saturated fatty alcohol with an ethylene-dicarboxylic acid which has been reacted with about 1/7 to 1/35 of its weight of a ethylenedicarboxylic compound of acidic character (for example maleic acid) are efficient agents for inhibiting the deposition of pigment in pigmented aqueous lacquers. Organic solutions of the salts are storage-stable. The salts can be incorporated into the lacquer during formulation of the lacquer or at a later point.
