Abstract: Dye composition comprises 0.1-30 wt.% non-ionic anthraquinone, quinophthalone or azo dye(s), 0.1-20 wt.% of a dispersant comprising a naphthalene sulfonic acid/formaldehyde condensate (I) with an average molecular weight of at least 11000, 0.1-90 wt.% mono- or polyhydric alcohol(s), 0-5 wt.% additives and optionally water to 100 wt.%. Independent claims are also included for: (1) printing of textile substrates by inkjet or sublimation transfer printing using the dye composition; (2) printed textile substrates produced as above.

Abstract: The invention relates to a method for producing a solution of tanning agents containing sulphone. In said method, a) a component A is produced as follows: a1) phenol is reacted with concentrated sulphuric acid or with oleum with an SO3 content of between 20 and 65 wt. %, or with a mixture of sulphuric acid and oleum with an SO3 content of between 20 and 65 wt. %, whereby the molar ratio of total sulphuric acid, calculated in the form of SO3 to phenol is between 0.7: 1 and 1.5: 1, at a temperature of between 100 and 180 DEG C to obtain a mixture containing phenolsulphonic acid, dihydroxydiphenyl sulphone and sulphuric acid, or the individual components are blended to produce a corresponding mixture; a2) said mixture is subsequently condensed at between 40 and 90 DEG C per mol of phenol units present with between 0.25 and 4 mol of urea and between 0.5 and 4 mol of an aliphatic aldehyde comprising between 1 and 6 C atoms, a3) optionally a pH value of between 4 and 5 is set by adding a base; b) a component B is produced as follows: b1) dihydroxydiphenyl sulphone is reacted with between 0.5 and 5 mol of an aliphatic aldehyde comprising between 1 and 6 C atoms and between 0.4 and 2 mol of sodium sulphite per mol of dihydroxydiphenyl sulphone, at a temperature of between 90 and 180 DEG C; b2) optionally a pH value of between 3.5 and 5.5 is set by adding an acid. c) Between 10 and 90 wt. % of component A is mixed with between 90 and 10 wt. % of component B, (the sum of A and B amounting to 100 wt. %) and if not already accomplished in steps a3) and b2), the pH value of the mixture is set at between 3.5 and 5.5.
