Abstract
1,165,661. Reactive dyes. FARBENFABRIKEN BAYER A.G. 28 Feb., 1968 [25 March, 1967], No. 9623/68. Heading C4P. The invention comprises reactive dyestuffs of the general formula wherein D is an organic dyestuff radical, Q is a divalent bridge member, n is 0 or 1, R is H or C 1 -C 5 alkyl or hydroxyalkyl group, R 1 is H or a substituent atom or group and R 2 is H or an optionally substituted alkyl, alkenyl, aralkyl, or aryl radical, the group -N(R)- being linked to an aromatic ring in D either directly or via a bridge grouping. The dyestuffs may contain more than one fluoropyrimidine radical. Q may be -CO-, alkylene, arylene, aralkylene or -CO-CH 2 -SO 2 - (SO 2 - being linked to the pyrimidine group). Radical D may be a mono- or dis-azo, optionally metallized, or tris-azo, phthalocyanine, anthraquinone, stilbene or nitro dyestuff radical, optionally containing sulphonic acid groups. They are prepared by known methods, for example by reacting a dyestuff or dyestuff intermediate containing an amino or an amide group having hydrogen on the nitrogen atom with a compound of the formula wherein R 1 and R 2 are as above and X is a radical which can be split off as an anion, the intermediates being converted e.g. by diazotization and/or coupling to dyestuffs which may then be acylated or sulphonated. Many examples are given and the dyestuffs dye hydroxyl group containing materials, e.g. natural or regenerated cellulose and nitrogen-containing materials, e.g. wool, silk and synthetic polyamides and polyurethanes in all shades.
