Abstract
1,184,165. Reactive dyes. FARBENFABRIKEN BAYER A.G. 5 April, 1968 [7 April, 1967], No. 16484/68. Heading C4P. The invention comprises reactive dyes containing at least one pyridazine containing at least one eliminatable fluorine substituent. (Eliminatable means the fluorine substituent will react with OH or amide groups of fibre material and will split off to form a covalent bond between dyestuff and fibre.) The preferred dyes have the general formula wherein D is a dye radical, e.g. of the mono-, di- or poly-azo which may be metallized, anthraquinone, phthalocyanine, stilbene or nitro series, R is H, C 1 -C 5 alkyl or hydroxyalkyl and R 1 is H or a substituent atom or group, D preferably containing at least one sulphonic acid group. They are prepared by introducing by known methods, e.g. condensation of an amine with a tetrahalopyridazine at least one fluoropyridazine radical into a dyestuff or dyestuff intermediate and when an intermediate is used, converting this, e.g. by diazotization and coupling, acylation or sulphonation, into the final dyestuff. Many dyes are prepared which give all shades on wool, silk, synthetic polyamides and polyurethanes and natural and regenerated cellulose.
