1,174,193. Dyeing synthetic materials. CIBA Ltd. 3 May, 1967 [11 May, 1966; 8 March, 1967], No. 20459/67. Heading D1B. Synthetic fibre material is dyed or printed with azo dyes free from sulphonic and carboxylic acid groups and which is of formula in which R 1 is a residue of a diazo component and, when it contains a halogen atom in 2- position to the azo group and an alkanecarbonyl, alkanesulphonyl or alkylated aminosulphonyl group in 4-position must contain no further halogen in the 5 or 6 position and when it contains a halogen in the 2-position and a nitro-group in the 4-position must contain no nitro in the 6-position to the azo group, R 2 is a benzene residue linked with the azo bridge in the para-position to the amino group, X is hydrogen, unsubstituted or substituted alkyl, aryl, aralkyl or cycloalkyl group, and Y is an alkylene radical to Which the cyclic nitrogen atom of a heterocyolic tertiary or quaternary amine is directly bound to an alkyl carbon atom and wherein N and X together with R@ may form a heterocycle. In particular Y is a pyridinium ethyl residue, and synthetic fibres of acrylonitrile, aromatic polyesters or asymmetric olicyanoethylene are dyed.
