Abstract: An optical brightener mixt., contg. 75-100 wt.% dicyano-substd. bis-styryl (DCBS) isomers of formulae (I)-(V) contains, per 100 pts.wt. (I)-(V), 25-50 pts. wt. (I); 30-60 pts.wt. (II); and 0.5-10 pts. wt. (III), as well as 1-30 pts. wt. (IV) and/or (V). Pref. the compsn. contains 85-100 wt.% (I)-(V), with an aq. compsn. contg. 3-25 wt.% (I)-(V) and 5-60 wt.% auxiliaries. The pref. (I)-(V) compsn. comprises 30-45 wt.% (I), 40-50 wt.% (II) and 0.5-5 wt.% (III), as well as 1-15 wt.% (IV) and/or (V).
