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).

Abstract: An agent, based on reducing agents and complexing agents, for dissolving insoluble iron(III) compounds in aqueous textile treatment baths which are at a pH of 10 or more, which agent has the following composition: a) from 4 to 65% by weight of one or more watersoluble hydroxycarbonyl compound or of an N- or O-acetal thereof, as the reducing agent, b) from 10 to 80% by weight of one or more complexing agent which complexes Fe++ ions at a pH of 10 or more and c) water in an amount equal to 100% minus the amounts of a) and b).
