Definitions

  • Alkylene is in particular a radical having 1 to 3 carbon atoms.
  • Acylamino is preferably understood to mean C 1 to C 3 alkylcarbonylamino, C 1 to C 3 alkylsulfonylamino, aminocarbonylamino or benzoylamino, optionally substituted by halogen or an ammonium group, but especially acetylamino, propionylamino or aminocarbonyl.
  • Halogen is preferably chlorine or bromine.
  • Anions An (-) are the colorless organic and inorganic anions customary for cationic dyes, for example chloride, bromide, iodide, hydroxide, hydrogen sulfate, sulfate, nitrate, dihydrogen phosphate, phosphate, carbonate, perchlorate, fluoroborate, chlorozincate, methosulfate, ethosulfate, acetate, Propionate, lactate, citrate, benzenesulfonate and toluenesulfonate.
  • cationic dyes for example chloride, bromide, iodide, hydroxide, hydrogen sulfate, sulfate, nitrate, dihydrogen phosphate, phosphate, carbonate, perchlorate, fluoroborate, chlorozincate, methosulfate, ethosulfate, acetate, Propionate, lactate, citrate, benzenesulfonate and toluen
  • the anion is generally given by the manufacturing process.
  • the dyes are preferably present as chlorides, hydrogen sulfates, sulfates, methosulfates, phosphates, acetates, lactates, citrates.
  • the anions can be exchanged for other anions in a known manner and can be present as mixtures.
  • the dyes (I) are used for dyeing paper either as dye-powder preparations or preferably in the form of concentrated dye solutions.
  • Powder preparations are made in the usual way with coupé agents such as sodium sulfate, phosphates, chloride, acetate or are marketed as spray drying brands.
  • the concentrated dye solutions can be of an aqueous or aqueous / organic type, with customary environmentally friendly and readily degradable organic additives being preferred, such as organic acids such as acetic acid, formic acid, amides such as formamide, dimethylformamide, urea, alcohols such as glycol, diglycol, diglycol ether, especially the latter Methyl or ethyl ether.
  • the concentrated dye solutions are prepared in a conventional manner, for example by dissolving the dye (as a paste or powder) in a suitable solvent or solvent mixture.
  • the dye powders or solutions are generally used after dilution with water for the continuous or discontinuous dyeing of paper.
  • the dyes are used for paper pulp dyeing or for paper surface dyeing. They are suitable for sized and unsized paper types based on bleached or unbleached pulp of different origins such as softwood or hardwood, sulfite and / or sulfate pulp.
  • the dyeing is preferably carried out at pH values from 4 to 8, in particular pH 5 to 7.
  • the dyeing temperature is generally 10 to 50, preferably about 20 ° C. (room temperature).
  • auxiliaries and fillers customary in paper dyeing and production can also be used when using the dyes according to the invention.
  • the dyes have excellent drawability when coloring paper.
  • the paper dyeings obtained with the dyes according to the invention are notable for very good fastness to water (fastness to bleeding) and fastness to acids, alkali and alum.
  • the dyes of the formula (I) are known, for example from US Pat. No. 602637, DE-PS No. 93499, DE-PS No. 95530 and DE-AS No. 1005486, and have hitherto been used for dyeing tannic cotton, half-wool and polyacrylonitrile used. It is therefore surprising that in the case of paper dyeing, even without auxiliaries, they produce almost colorless waste water with good wet fastness properties of the dyeings obtained.
  • a desiccant consisting of 60% wood pulp and 40% unbleached sulfite pulp is beaten with water in the Dutch and ground to a degree of 40 ° SR so that the dryness is a little over 2.5%, and then with water to an exact 2.5% dryness of the thick matter adjusted.
