Definitions

  • R 1 'and R 2 ' have the meaning given above for R 1 and R 2 .
  • R 3 'and R 4 ' together are a fused phenyl ring or in the 5- and 7-position hydrogen or chlorine, alkyl, phenyl, X oxygen or sulfur and B 'a group of the formulas means, where R 6 'is alkyl, chloroalkyl, alkoxyalkyl, hydroxyalkyl or a group of the formula - (CH 2 CH 2 O) n -R, where n is 1, 2 or 3 and R is hydrogen or alkyl, R 11 ' is phenyl , which can be substituted by one or two chlorine atoms, one or two alkyl, alkoxyalkyl groups, a phenyl, cyano, carboxylic acid, carboalkoxy, carboxamide, sulfonic acid, sulf
  • R 3 "and R 4 " are hydrogen or alkyl
  • n 1 or 0 and B " is a group of the formulas -CN or -COOalkyl and R s "means alkyl or methoxyethyl.
  • R s is a group of the formulas -CN or -COOalkyl
  • R s means alkyl or methoxyethyl.
  • alkyl and alkoxy groups as well as other, derived groups of 1 to 4 carbon atoms.
  • the compounds of formula 1 are from DE-PS 1 594 834 and the compounds of formula 2 known from DE-OS 2 709 924 and from the published Japanese patent applications Sho 51/40090 and Sho 70/4568.
  • the mixing ratio for the individual components is between 1 and 99% by weight for the compound of the formula 1 and correspondingly 99 to 1% by weight for the other compound of the formula 2.
  • These compounds of the formulas 1 and 2 can also be used individually can be used in any mixture with one another, the mixing ratio of these compounds with one another being completely uncritical and being able to be varied as desired.
  • a mixing ratio of 50 to 99% by weight for the compound of the formula 1 and 50 to 1% by weight of the compound of the formula 2 is preferred.
  • the optimal mixing ratio of all compounds depends on the structure of the respective compounds in individual cases and can easily be determined by simple preliminary tests.
  • the individual components are dispersed in a liquid medium e.g. Water brought into the commercial form.
  • the individual components can be dispersed individually and the dispersions can then be added together.
  • the individual components can also be mixed together in bulk and then dispersed together. This dispersion process takes place in the usual way in ball mills, colloid mills, bead mills or dispersion kneaders.
  • the mixtures according to the invention are particularly suitable for lightening textile material made from linear polyesters, polyamides and acetyl cellulose. However, these mixtures can also be used with good results in mixed fabrics which consist of linear polyesters and other synthetic or natural fiber materials, in particular fibers containing hydroxyl groups, in particular cotton.
  • optical brighteners are applied under the conditions customary for the use of optical brighteners, for example using the exhaust process at 90 ° C. to 130 ° C. with or without the addition of accelerators (carriers) or using the thermosol process.
  • the water-insoluble brighteners and the mixtures according to the invention can also be used in organic solvents, e.g. Perchlorethylene, fluorinated hydrocarbons can be used in solution.
  • the textile material can be treated in the exhaust process with the solvent liquor, which contains the optical brightener, or one can impregnate, splash, spray the textile material with the brightener-containing solvent liquor and then dry at temperatures of 120-220 ° C, whereby the optical brightener is completely fixed in the fiber. This gives an excellently brightened product with excellent light resistance and resistance to oxidizing and reducing agents, the degree of whiteness of the mixture being significantly higher than the degree of whiteness which can be achieved with the same amount of only one compound of formula 1 or 2.
  • Fabric sections made of polyester staple fibers are washed, dried and impregnated on a foulard with aqueous dispersions which either contain only one brightener of formula 1 or 2 for comparison or a mixture of both brighteners in a weight ratio of 8 to 2 based on the active substance.
  • the brighteners of formula 1 are taken from a commercially available dispersion (20% setting).
  • the brighteners of formula 2 are used in a 10% dispersion in polyvinyl alcohol.
  • the total amount of brightener is 1.66 g / l.
  • the material is squeezed between rollers with a foulard so that there is a moisture absorption of approx. 80%.
  • the material that has been sealed in this way is then dried at 110 ° C. and thermosolated on a tenter at the temperatures given in the table.
  • the respective degrees of whiteness according to Ganz were obtained.
