New reactive azo dyes, used for dyeing or printing substrate with hydroxyl groups or nitrogen atoms, especially cotton, contain alkyl- or phenyl-thio-, -sulfinyl- or -sulfonyl-triazinyl-(alkyl)-imino group(s)

摘要

New reactive dyes (I) are azo, disazo, triphenodioxazine, anthraquinone, formazan and phthalocyanine dyes with 2-(alkyl- or phenyl-thio-, -sulfinyl- or -sulfonyl)-1,3,5-triazinyl-(alkyl)imino substituent(s) and optionally other fiber-reactive group(s). New reactive dyes (I) of formula (A) are azo, disazo, triphenodioxazine, anthraquinone, formazan and phthalocyanine dyes with 2-(alkyl- or phenyl-thio-, -sulfinyl- or -sulfonyl)-1,3,5-triazinyl-(alkyl)imino substituent(s) and optionally other fiber-reactive group(s): [Image] X : S(O) pA; X' : S(O) qA m : 0 or 1; n : 1, 2 or 3; p, q : 0, 1 or 2; Chr : a (substituted) azo, disazo, triphenodioxazine, anthraquinone, formazan or phthalocyanine dye group, linked to the triazine ring by an (alkyl)imino group; m : 0; Z : a group of formula (IIA-E); m : 1; n : 1; Z may also : group of formula (IIF): a : 0 or 1; R 1 - 6hydrogen (H) or (substituted) 1-4C alkyl or phenyl; L 1C 2H 4 or C 3H 6; L 2L 1 or phenyl; Y : a group eliminated under alkaline conditions; A : (substituted) 1-6 C alkyl or phenyl. The full definitions are given in the DEFINITIONS (Full Definitions) Field. An independent claim is also included for substrates with hydroxyl groups or nitrogen atoms, dyed with dye(s) (I).
