Definitions

  • Optical brighteners are often used as mixtures of two or more different types, because such mixtures show a synergistic effect in that the degree of whiteness of the mixture is higher than the degree of whiteness of the same amount of the individual components.
  • the invention therefore relates to mixtures of optical brighteners composed of 1 to 99 parts by weight of a compound of the formula 1 wherein R1 and R2 are the same or different and are -CN, -COOCH3 or -COOC2H5, and 99 to 1 part by weight of one or more compounds of the formulas 2 to 10
  • the mixtures preferably consist of 25 to 75 parts by weight of a compound of the formula 1 and 75 to 25 parts by weight of one or more of the compounds of the formulas 2 to 9, in particular the compounds of the formulas 3, 4 and 8, the preferred mixing ratio to the compound of the formula 8 20 to 50 to 80 to 50, while the preferred mixing ratio of a compound of formula 1 with a compound of formula 10 is 5 to 15 to 95 to 85, especially about 10 to 90 parts by weight.
  • R1 and R2 are preferably the same and are especially -CN or also -COOC2H5.
  • Preferred compounds of formula 10 are: 1,4-bis (2-cyanstyryl) benzene 1- (2-cyanstyryl) -4- (4-cyanstyryl) benzene 1- (2-cyanstyryl) -4- (3-cyanstyryl) benzene and 1- (3-cyanstyryl) -4- (4-cyanstyryl) benzene.
  • the compounds of the formulas 2 to 10 can also be used individually in any mixture with one another together with a compound of the formula 1 as optical brighteners, the mixing ratio of the compounds of the formulas 2 to 10 to one another being uncritical and being able to be varied depending on experience.
  • the mixtures according to the invention are obtained either by jointly dispersing compounds of the formula 1 with one or more compounds of the formulas 2 to 10 in the stated mixing ratio or else by separate dispersing of the components and mechanical mixing.
  • the optimal mixing ratio depends on the type of connection and can be easily determined by simple tests.
  • the present invention further relates to the use of mixtures of a compound of the formula 1 with one or more compounds of the formulas 2 to 10 for the optical brightening of polyester fibers and textile material containing polyester fibers, and agents for the optical brightening of polyester fibers and Textile materials containing polyester fibers, containing mixtures of a compound of formula 1 with one or more of the compounds of formulas 2 to 10.
  • the mixtures according to the invention are particularly suitable for optically brightening textile materials made of linear or modified polyesters. They can be applied to the textile material by known methods, for example by the exhaust process at 90 to 140 ° C or by the pad thermal process at 160 to 220 ° C.
  • the mixtures according to the invention are distinguished by very good dyeing behavior. In addition to a higher degree of whiteness compared to the corresponding proportions of the individual components, the mixtures have an improved brilliance of the brightenings.
  • a polyester fabric (Terylene type 540) is at 40 ° C on a dyeing machine at a liquor ratio of 1 to 20 with an aqueous bath containing 0.1% by weight of an optical brightener from a mixture of 25 parts by weight of the compound of the formula and 75 parts by weight of the compound of the formula as well as 1 g / l of a fatty alcohol polyglycol ether (Irgasol P) treated.
  • the temperature is increased to 120 ° C. within 30 minutes and left at this level for a further 30 minutes. Then you cool down to 40 ° C within 15 minutes.
  • the fabric is rinsed in flowing deionized water for 30 seconds and dried at 80 ° C.
  • the polyester fabric treated in this way has a high lightening effect.
  • a polyester fabric (Terylene type 540) is padded at room temperature with an aqueous liquor containing 1 g / l of the brightener mixture of 50 parts by weight of the compound of the formula 1 and 50 parts by weight of the compound of the formula 4 (calculated on active substance) in dispersed form and 1 ml / l Invadin JFC 200%.
  • the squeezing effect is 65%.
  • polyester fabric treated in this way has a high lightening effect.
