| abstract | 1338549 Dyeing synthetic fibres BAYER AG 28 April 1972 [29 April 1971] 19788/72 Heading D1B [Also in Division C2] Compounds of formula I: in which R is C 5-21 alkyl, C 5-21 alkenyl or optionally substituted alicyclic, aralkyl, aryloxyalkyl, or aryl, R, is C 2-4 alkylene, each of R 2 and R 3 is C 1-4 alkyl or C 1-4 hydroxyalkyl or R 2 and R 3 , together with the adjacent nitrogen atom, form a 5- to 7-membered heterocyclic ring which optionally contains a further heteroatom, A is a radical containing at least 2 isocyclic rings which may be joined together and X is an anion, are used as dispersing agents in the dyeing of fibre materials with cationic dyestuffs. Examples 7 to 10 relate to the dyeing of polyacrylonitrile fibres. |
