Fiber-reactive anthraquinone dyes: Fiber-reactive anthraquinone dyes. Jaeger, Horst (Bayer A.-G., Ger.). Ger. Offen. DE 2657146 22 Jun 1978, 15pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09B062-06. APPLICATION: DE 76-2657146 16 Dec 1976. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Reactive blue dyes are prepd. which have the general structure I, where R = H or substituted C1-4 alkyl, R1 = substituted amino, etherified hydroxyl or thiol, or substituted hydrocarbyl, R2 = H or halogen, R3 = H, C1-4 alkyl, C1-4 alkoxy, or halogen, and n = 1-4. Thus, successive reaction of cyanuric fluoride [675-14-9] with 2,5-(NaO3S)2C6H3NH2 [41184-20-7] and Na 1-amino-4-[3-[(methylamino)methyl]anilino]anthraquinone-2-sulfonate [67427-15-0] gave I [R = Me, R1 = 2,5-(HO3S)2C6H3NH, R2 = R3 = H, n = 1) [67523-27-7], which dyed and printed cotton fabric light- and washfast blue shades.
