- A is a sulfonic acid residue, hydrogen, C1-C4-alkyl, C1-C4-alkoxy or halogen and B is hydrogen, C1-C4-alkyl, C1-C4-alkoxy or halogen, with the condition that at least one substituent A is a sulfonic acid residue is and m, n, o, p independently of one another represent a number 1 or 2.
- Particularly preferred compounds are compounds of the formulas and where A, B and n have the above meaning and M is a salt-forming cation.
- halogens are fluorine, chlorine and bromine, but especially chlorine.
- C1-C4 alkyl radicals are unbranched and branched alkyl radicals such as the methyl, ethyl, n- and iso-propyl, n-, sec- and tert-butyl radical. These C1-C4 alkyl radicals can in turn be substituted with e.g. Aryl (phenyl, naphthyl), C1-C4 alkoxy, OH, halogen, sulfo or CN groups.
- Salt-forming cations M are e.g. Alkali metal, ammonium or amine salt ions.
- Amine salt ions are preferred those of the formula H+NR1R2R3 in which R1, R2 and R3 independently of one another are hydrogen, alkyl, alkenyl, hydroxyalkyl, cyanoalkyl, halogenoalkyl or phenylalkyl or in which R1 and R2 together are the addition to a 5-7-membered saturated Represent nitrogen heterocycle, which may additionally contain a nitrogen or oxygen atom as a ring member, for example a piperidine, piperazine, pyrrolidine, imidazoline or morpholine ring, while R3 is hydrogen.
- Preferred salt-forming cations are akali metal salts, Na+ and K+ being particularly preferred.
- Preferred distyrylbiphenyl compounds of the formula (4) are those in which the cation M is an alkali metal, ammonium or amine ion, potassium and sodium being of particular importance for practical reasons.
- Preferred mixtures each consist of 5 to 30% by weight, based on the total weight, but not more than 45% by weight, of two, three or four brighteners of the formulas (2), (3), (7) and (8) ,
- the ratio of the optical brighteners to one another is between 1: 9 and 9: 1, preferably between 1: 4 and 4: 1.
