Abstract: New bis-imidazolinium salts are of formula (I): (where R is an (un)-satd. linear or branched 7-29, pref. 11-17C (hydroxy)-alkyl gp.; Z is an (un) satld. 2-12C alkylene gp., opt. with OH, CO, CN or Cl substit, or with -O-, -S- or -NR- in the chain, R being H or 1-4C alkyl; X is an anion, pref. Cl or Br). (I) are prepd. by heating approx. equimolar amts. of aminoethylhydroxyethylamine and 8-30 (12-18)C fatty acid(s) for 1-10 hrs. in the absence of air at 130-220 degrees C to an amide, then heating for 10-12 hrs. in the presence of a water eliminating agent under reduced pressure at 180-230 degrees C and reacting for 1-15 hrs. in the absence of air with ca. 0.5 mole (un)satd. 2-12 C alpha, omega-dichloro-or-dibromo-cpd., opt. with OH, CO, CN or Cl substit. or with -O-, -S- or -NR- in the chain, at 40-200 degrees C. 0.1-2.5% (I), w.r.t. the wt. of the fibres, is used as a retarder (to aid levelling) in the dyeing of polyacrylonitrile fibres or (mixed textiles with basic dyes. Lower concns. of (I) are required and the dye absorption phase is shorter.

Abstract: Prodn. of level dyeings on acrylic fibres with basic dyes is achieved by use of title cpds. of formula (I): (where R1, R3 and R4 are H or 1-4C alkyl; R2 is 1-4C alkyl or benzyl; and X is residue of an inorg. acid or a 1-3C alkylsulphuric acid), pref. by treating the dyed goods in a blank bath.
