    Abstract: Yellow to organe azo dyes for natural and synthetic polyamides, e.g. wool, silk, leather, nylon 6 or 6,6; cellulose esters, e.g. -2 1/2 and triacetate and synthetic linear polyesters, have the formula: (where D is a diazo component gp.; X is 2-9 C opt. substd. carbamoyl or carboxylate; M is H, Na, K or opt. substd. NH4 and n is 0 to 3). They are prepd diazotising amines DNH2 and coupling with cpds. (where p is 0 or 1) or by sulphonating cpds. of formula: D-NH-=CX- , esp. with oleum.

    Abstract: New dyes have the formula (I): where D is the residue of a diazo component of the benzene, naphthalene, diphenyl, azobenzene, thiophene, benz(iso)thiazole, thiazole, (benz)triazole, indazole, pyrazole or anthraquinone series, X is CN or CONH2, R is H, 1-8C alkyl, alkyl substd. by OH, 1-8C alkoxy, COOH, 2-6C carbalkoxy, 1-10C acyloxy or is not >8C alkylamino or interrupted by O, phenyl (opt. substd. by Cl, CH3, C2H5, OHCH2CH2, CH3O or C2H5O), cyclohexyl, benzyl, phenylethyl or omega-N-pyrrolidonyl-alkyl with 2-3C in the alkyl gp., R1 is H, 1-8C alkyl, alkyl substd. by OH, 1-8C alkoxy, or is not 8C alkylamino, R and R1 together with the N atom represent the residue of pyrrolidine, piperidine, morpholine or (N-methyl)-piperazine, R2 is as in R, R3 is as in R1, and R2 + R3 are as in R + R1. The dyes are yellow to greenish-blue, and are suitable for dyeing or printing polyacrylonitrile, polyamides, cellulose esters and polyesters. Strong dyeings with good resistance, esp. to thermo-fixing and light are obtd.

    Abstract: 1,269,389. Azo and azomethine dyes. BADISCHE ANILIN- & SODA-FABRIK A.G. 23 July, 1969 [24 July, 1968], No. 37036/69. Heading C4P. Metal-containing azomethine and azo dyes are of formula (in which A completes an optionally substituted benzene or naphthalene ring free from SO 3 H groups; M is a metal of atomic no. 23-92). Preferably A completes a naphthalene or benzene ring optionally substituted by NO 2 , Cl, CH 3 , N(CH 3 ) 2 , SO 2 N(CH 3 ) 2 , CO 2 H or CONHC 6 H 5 , pnitrophenylazo or (p-phenylazo)phenylazo, and Me is Cu or Ni. The dyes may be prepared by condensing ortho- OHO-A-OH with 2-(8- aminoquinolyl-(2))-indandione-(1,3) to form an azomethine dye of formula and simultaneously or subsequently treating with a metallizing agent.
