Formazan reactive azo dyes, their production and their use

Formazan reactive azo dyes, their production and their use.Some chemicals with cas registry numbers like 120-98-9 are also used. Gisler, Markus (Clariant International Ltd., Switz.).Chemical with cas number 120-98-9 also plays role. PCT Int. Appl. WO 2003011979 A1 13 Feb 2003, 17 pp. DESIGNATED STATES: W: BR, CN, ID, IN, JP, KR, MX, US, ZA; RW: AT, BE, CH, CY, DE, DK, ES, FI, FR, GB, GR, IE, IT, LU, MC, NL, PT, SE, TR. (English). (World Intellectual Property Organization). CODEN: PIXXD2. CLASS: ICM: C09B062-24. APPLICATION: WO 2002-IB2986 29 Jul 2002. PRIORITY: CH 2001-1423 31 Jul 2001. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 28, 40 This invention relates to reactive formazan dyes (I; M = Cu, Ni; Q, Q' = H, sulfo; R, R' = H, C1-4-alkyl, C1-4-alkoxy, sulfo; X, Y = halogen; m, n, o, r, s, t = 1-2; u = 0, 1; v < 3), their prepn., their use for dyeing and printing of hydroxyl-contg. or nitrogenous org. substrates and substrates dyed or printed with these compds. I have good fastness properties on cotton. In an example, 3-[4-(2-sulfoethylamino)phenylazo]benzaldehyde was treated with 2-hydrazino-4-sulfobenzoic acid and CuSO4 .5H2O and the product was coupled with diazotized 2-aminophenol-4,6-disulfonic acid to give a Cu formazan product. The formazan was hydrolyzed to remove the sulfoethyl group and then condensed with 2,4,6-trifluoropyrimidine to give a green dye for cotton. ..
