| titleOfInvention | New azo colouring matters containing 2-hydroxyquinoline residues |
| abstract | The preparation of substituted quinolines of formula <FORM:0896472/IV (b)/1> wherein the ring B is substituted by one or two halogen, alkyl or alkoxy substituents by condensing an appropriate m-phenylene-diamine with ethyl acetoacetate or diketene and treating the condensate with concentrated hydrochloric acid is described. The preparation of 7-amino-2-hydroxy-4 : 5- and 4 : 6-dimethylquinolines, 7 - amino - 6 - chloro - or - methoxy - 2 - hydroxy - 4 - methylquinoline and 7 - amino - 2 - hydroxy - 4 : 5 : 8 - trimethylquinoline is detailed.ALSO:The invention comprises monoazo pigment dyes which in one of their tautomeric forms are of formula <FORM:0896472/IV (c)/1> wherein A is the residue of a coupling component free from sulphonic and carboxylic acid groups and the ring B has one or two halogen, alkyl or alkoxy substituents. They are prepared by coupling a suitable diazotised 2-hydroxy-4-methyl-7-aminoquinoline (see Group IV (b)) with a coupling component free from sulphonic and carboxylic acid groups. The monoazo pigments are used to colour paints and polymers or in the printing of wallpaper and textiles in red, yellow and blue shades. Preferred diazo and coupling components are 7-amino-2-hydroxy-4 : 5- or -4 : 6-dimethylquinoline, 7-amino-2-hydroxy-4 : 5 : 8-trimethylquinoline and 7-amino-6-methoxy - 2 - hydroxy - 4 - methylquinoline; 2 - hydroxy - 3 - naphthoic - (41 - methoxy - 21 - methyl-anilide) or -(51-chloro-21 : 41dimethoxy-anilide), 1 - p - tolyl - 3 - methyl - 5 - pyrazolone and acetoacet-2 : 4-dimethyl- or -4-ethoxy- or -2-chloro- or -4-chloro-2 : 5-dimethoxy-anilide. Many examples are described. |
