Abstract: Pigment compsn. useful as pigment masterbatches contains (I) 10-90 wt. % finely divided pigment, and (II) 90-10 wt. % water-sol. polystyrene-sulphonate as dispersing agent. Compsn. does not coagulate or sediment in aqs. binders, even in high concns. and remains stable for long periods. The compsn. pref.also contains up to 50 wt. % water (II) is pref. derived from a polystyrene with an average mol. wt. of 300-50,000, contains 0.2-1 sulphonate gp. per styrene monomer unit, and is in the form of a sodium, potassium, ammonium or alkyl-ammonium salt. (I) may be an inorg., quinacridone, quinophthalone, azo, anthraquinone, phthalocyanine, indigo or oxazine pigment, or a pigment derived from perylen-3,4,9,10-tatracarboxylic acid.

Abstract: A process for dyeing textile materials, containing natural and/or synthetic fibers, in an aqueous liquor by means of dyes which are sparingly soluble or insoluble in water, in the presence of dyeing assistants, wherein the dispersant used is a water-soluble sulfonic acid which is derived from a random copolymer of olefins of 3 to 6 carbon atoms and styrene and/or substituted styrenes and/or their alkali metal salts or ammonium salts.

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.
