Abstract
1410938 Azamethin dyes CIBA-GEIGY AG 20 Dec 1972 [23 Dec 1971] 58888/72 Heading C4P Dyes of formula are prepared by slowly adding not more than 4 mole equivalents of dimethyl, diethyl or dipropyl sulphate or p-toluenesulphonic acid methyl or ethyl ester, to a dye of formula in an aqueous (preferably alkaline) medium at at 5-75‹ C. In the formula R 1 is methyl, ethyl or propyl; R 2 is H, methyl, ethyl or propyl; Y is of formula -N(B)(D) or B is H, 1-4 C alkyl, cyclohexyl, phenyl or benzyl, and may be substituted by one or more of CN, nitro, carbamoyl, OH, amino, 1-4 C alkoxy, Cl or Br; D is phenyl or a 5- or 6- membered heterocyclic ring, and may be fused to a benzene ring which phenyl group, heterocyclic ring or fused benzene ring may be substituted by one or more at Cl, Br, OH, CN, carbamoyl, 1-4 C alkyl, 1-4 C alkoxy, phenoxy, NO 2 or acetylamino; or B and D complete a 5- or 6-membered ring to which may be fused one or two benzene rings; Q and Q 1 each complete a 5- or 6-membered ring which may be substituted as D above and may be fused to one or two benzene rings; R 3 is methyl, ethyl, propyl or benzyl; n and m are each 1 or 2; A is an anion. The examples describe dyes in which Q completes a pyridinium, quinolinium, acridinium, benzothiazolium, benzoxazolium, benzimidazolium, thiazolium, oxazolium or imidazolium nucleus; and Y is -N(B)(D) in which B is H, CH 3 , C 2 H 5 , C 3 H 7 C 4 H 9 or cyclohexyl and D is pyridinyl or phenyl which may be substituted by Cl, Br, CH 3 , phenoxy, NO 2 CN, CONH 2 , OH, OCH 3 or acetylamino, or B and D together complete a 2,3-dihydroindole, carbazole or tetrahydroquinoline ring, or Y is -N=Z in which Z is a N-methyl-(quinolin)-, -(benzothiazol)-,-(thiazol)-,-(oxazol)-or-(benzoxazol)-2-ylene ring, a 1,3-dimethyl-(imidazol)-, -(benzimidazole)-or-(1,3,4-triazine)-2-ylene ring, a N-methyl-(pyridin)- or -(quinolin)-ring, or a N - methyl - isoquinolin - 1 - ylene, 3 - ethyl- 1,3,4 - thiadiazol - 2 - ylene or 4 - benzyl - 1,2,4- thiadiazol-4-ylene ring. The dyes are used to colour polyacrylonitrile and acid-modified polyester and polyamide fibres in yellow shades.
