Definitions

  • Formyl-C 1 - to C 3 -alkyl radicals are, for. B. -CH 2 CHO or CH 3 -CH-CHO.
  • the mixtures according to the invention are obtained either by jointly dispersing compounds of the formulas I and II in the stated mixing ratio or else by separate dispersing of the components and mechanical mixing.
  • Preferred mixing ratios are in the range from 10 to 90% of compounds of the formula I.
  • the optimum mixing ratio depends in each case on the type of the respective compounds of the brighteners mentioned under the formulas I and II. It can easily be determined by simple preliminary tests.
  • the mixtures according to the invention are particularly suitable for the optical brightening of textile materials made of linear polyesters, polyamides and of acetyl cellulose.
  • the mixtures according to the invention can be applied to the textile material by known methods, for example by the exhaust process at 90-140 ° C with or without the addition of dyeing accelerators (carriers) or by the thermosol process at temperatures from 160-210 ° C.
  • the mixtures according to the invention are distinguished by very favorable dyeing behavior.
  • the advantage of the mixtures compared to the individual components can be seen in the fact that this gives an unexpected synergistic effect with regard to the degree of whiteness, i.e. mixtures according to the invention result in a higher degree of whiteness than would be expected if the proportions of the individual components were taken into account. The same applies to the brilliance of the brightening.
  • EP-A1-0023026 In the not previously published older EP-A1-0023026 are mixtures of 0.05-0.95 parts by weight of 1,4-distyrylbenzene-CN derivatives and 0.95-0.05 parts by weight of a further optical brightener described. In addition to numerous compounds of various types, this also includes 4,5-alkoxy-N-alkylnaphthalimides, e.g. B. 4,5-Dimethoxy-N-methyl-naphthalimide.
  • Preferred mixing ratios are in the range of about 70-90: 30-10 (I: II) when high degrees of whiteness are desired and in the range of 30-60: 70-40 (I: II) when high light fastness is important .
  • Polyester staple fiber fabric is washed as usual, dried and impregnated on a padder with an aqueous dispersion which contains 1 g / l of a mixture of the optical brighteners of the formula 1 contains 70 parts I and 30 parts II in a mixing ratio.
  • Polyester fiber fabric is treated as described in Example 1 with an aqueous dispersion containing 1 g / l of a mixture of the optical brighteners of the formula I. contains.
