摘要
1. Dyestuffs for cyclic or straight polyfluoropolyoxyalkylenes, of general formula: Q[B - (A)s ]t (III) or [ (Q)s -B]2 A (IV where: Q = an organic group containing a chromophore group, free from free or salified sulphonic and/or carboxylic groups, and/or sulphon-amidic groups; A = a perfluorooxyalkylene chain, which is monovalent in formula (II) and divalent in formula (III); B = an organic at least divalent group; s, t = 1 or 2, respectively. 2. Compositions comprising cyclic or straight polyfluoropolyoxyalkylenes and at least a dyestuff of formula (III) or (IV) dissolved therein.
