Metal formazan dyes: Metal formazan dyes. (Sumitomo Chemical Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59058059 A2 3 Apr 1984 Showa, 11 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09B062-04. APPLICATION: JP 82-170426 28 Sep 1982. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) The title dyes of free-acid form I [R = water-solubilizing group; n, m = 0-3, n + m = 1-3; R1 = halogen; R2 = (un)substituted lower alkyl; R3 = (un)substituted Ph, naphthyl; Z = (un)substituted phenylene, naphthylene; Z1 = O, CO2; Z2 = alkylene, alkenylene, phenylene, naphthylene, heterocycle residue; M = metal (at. no. 27-29)] were prepd. and used for dyeing cotton. Thus, 2-carboxyphenylhydrazine-5-sulfonic acid [77734-51-1] was treated with benzaldehyde [100-52-7] to obtain the hydrazone [77734-52-2] which was then treated with diazotized 3-acetamido-2-hydroxyaniline-5-sulfonic acid [40306-75-0], coppered, hydrolyzed (AcNH ? NH2), condensed with cyanuric chloride [108-77-0], treated with N-ethylaniline [103-69-5], and salted to give a dye of free-acid form II [91074-70-3], bright blue on cotton.

Reactive azo dyes: Reactive azo dyes. Mennicke, Winfried; Fuerstenwerth, Hauke (Bayer A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3216787 A1 10 Nov 1983, 42 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09B062-008; C09B062-012; C09B029-33; D06P001-38. APPLICATION: DE 82-3216787 5 May 1982. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Dyes of general structure I (R = diazo component residue; X = O, S, NH, substituted NH; Z = direct bond or bridging group; R1 = H, alkyl; Q = fiber-reactive group; m = 1 or 2; ring A may be substituted) and transition metal complexes of I are prepd. I and their complexes are esp. 88475-08-5 and 88475-12-1 which are cas registry numbers of substances are two of reagents here. useful as dyes for cotton, polyamide fibers, and wool. Thus, diazotization of 2,3,5-HO(AcNH)(HO3S)C6H2NH2 [40306-75-0] and coupling with 2-acetonylbenzothiazole [36874-53-0], deacetylation, complexing with CoCl2, and reaction with 5-chloro-2,4,6-trifluoropyrimidine [697-83-6] gave II [88475-08-5], a light- and wetfast chocolate brown dye for cotton and wool. Yellow, orange, and other brown dyes were also prepd. .
