Dioxazine fiber-reactive dyes

Dioxazine fiber-reactive dyes. Nishikuri, Masao; Omura, Takashi; Takeshita, Akira (Sumitomo Chemical Co., Ltd. , Japan). Ger. Offen. DE 3403087 A1 9 Aug 1984, 39 pp. (German).Some chemicals with cas registry numbers like 93206-97-4 are also used. (Germany). CODEN: GWXXBX. CLASS: IC: C09B062-04; C09B019-00; D06P001-382; D06P001-40. APPLICATION: DE 84-3403087 30 Jan 1984. PRIORITY: JP 83-17978 4 Feb 1983. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Polyfunctional reactive dioxazine dyes (I) are prepd., where R = H, halogen, lower alkyl, or CN; R1, R2, and R3 = H or (un)substituted lower alkyl; R4 = (un)substituted lower alkyl; R5 = halogen; Z = alkylene, cycloalkylene, or arylene; Z1 = (un)substituted phenylene or naphthylene; Q = SO2CH:CH2 or SO2CH2CH2R6 (R6 = alkali-removable group); l and m = 0-3; m ￡3; and l + m + n ￡4. I give fast blue dyeings with good build-up. Thus, chlorosulfonation of 8,18-dichloro-5,15-diethyl-5,15-dihydrocarbazolo[3',2':5,6][1,4]oxazino[ 2,3-b]indolo[2,3-i]phenoxazine and reaction with 2,5-(H2N)2C6H3SO3H [88-45-9], cyanuric chloride [108-77-0], and then 3-EtNHC6H4SO2CH2CH2OSO3H [83574-63-4] gave I (R = Cl, R1 = R4 = Et, R2 = R3 = H, Z = 3-sulfo-1,4-phenylene, Z1 = m-C6H4, Q = SO2CH2CH2OSO3H, l = m = 0, n = ~2) (II) with lmax 573 and 630 nm (H2O). Other I were similarly prepd. II dyed cotton brilliant blue shades with good fastness to light, perspiration, and chlorine. .

Reactive monoazo dyes

Reactive monoazo dyes. (Sumitomo Chemical Co., Ltd., Japan).In this experiment, several chemicals are used like 93090-63-2 Jpn. Kokai Tokkyo Koho JP 59122549 A2 16 Jul 1984 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09B033-10. APPLICATION: JP 82-231040 28 Dec 1982. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) The title dyes were prepd. having a general formula of free-acid form I (R = substituted phenyl residue; R1 = (un)substituted alkyl; R2 = SO2CH:CH2, SO2CH2CH2R3; R3 = alkali-removable group; Z = (un)substituted phenylene, sulfonaphthylene] and used for dyeing cotton in red shades. Thus, cyanuric chloride [108-77-0] was condensed with H acid [90-20-0] and then with N-ethyl-3-(2-sulfatoethylsulfonyl)aniline [83574-63-4], and the condensate was coupled with diazotized 2-aminobenzenesulfonic acid [88-21-1] and salted to give II [93090-64-3]. .
