ABSTRACT:
Water-soluble acid addition or quaternary ammonium salts of compounds produced by acylation of an excess of diethylene triamine by isophthalic or terephthalic acid or a functional derivative thereof, subsequently cyclizing the product to afford imidazoline groups, and reacting the product further by way of acylation with a bifunctional acylating agent which is a saturated aliphatic dicarboxylic acid or a functional derivative thereof, or a functional derivative of carbonic acid. Such salts are useful for eliminating or preventing the brightening effect on materials, e.g. such fibrous material as textiles and paper, of anionic optical brightening agents.
