Definitions

  • the present invention relates to a process for dyeing paper in blue tones with certain disazo dyes.
  • Dyes which are suitable for dyeing paper in blue tones have long been known from the prior art (cf. e.g. C.I. Direct Blue, 23 850; C.I. Direct Blue, 24400).
  • anionic disazo dyes which include can be used for dyeing and printing paper in red shades.
  • FR-A-456 232 discloses certain disazo dyes which can be converted into trisazo dyes by reaction with a diazo component.
  • substituents can in turn be substituted by substituents customary in dye chemistry, for example halogen, in particular Cl, OH, C1-C4alkoxy, acyloxy, for example acetoxy, C1-C4alkyl, SO3H, COOH.
  • substituents customary in dye chemistry for example halogen, in particular Cl, OH, C1-C4alkoxy, acyloxy, for example acetoxy, C1-C4alkyl, SO3H, COOH.
  • Alkyl preferably stands for optionally substituted C1-C Alkyl alkyl, aryl, preferably for optionally substituted phenyl and aralkyl preferably for optionally substituted benzyl.
  • the dyes are prepared in a known manner by coupling diazotized azo dyes of the formula with coupling components of the formula
  • X NH2
  • the dyes are generally used in the form of their salts for dyeing, in particular the alkali salts (Li, Na, K), the ammonium salts, mono-, bis- or tris-C2-C4-alkyl-ammonium salts, in particular also the C2-C4- Alkanol-ammonium salts.
  • alkali salts Li, Na, K
  • ammonium salts mono-, bis- or tris-C2-C4-alkyl-ammonium salts, in particular also the C2-C4- Alkanol-ammonium salts.
  • the radicals R5 can be the same or different.
  • the dyes can also be used as concentrated, aqueous solutions.
  • the blue paper dyeings obtained are notable for good light and wet fastness (bleeding fastness), as well as acid, alkali and alum fastness. Attention should also be drawn to the brilliance and clarity of the color tones. Furthermore, the combination behavior with suitable dyes is very good.
  • a desiccant consisting of 60% wood pulp and 40% unbleached sulfite pulp is beaten in the Dutch and ground to a degree of grinding of 40 ° SR so that the dryness is slightly above 2.5%, and then adjusted to 2.5% dryness of the thick matter with water .
  • bleached sulfite pulp is used to produce the thick stock and this thick stock is used for dyeing, blue paper dyeings and practically dye-free waste water are obtained by the above-mentioned processes.
