Ammonium salts of metal complex dyes containing sulphonic acid groups |
| abstract |
The invention comprises any ammonium salt derived from a 1 : 1 chromium complex of an azo or azomethine dye which contains a sulphonic acid group and a primary, secondary or tertiary amine whose nitrogen atom is substituted by an aliphatic radical containing at least one ether oxygen atom and which aliphatic radical may in turn have aromatic substitution. Among the amines specified for use in the process are 1-methoxy-3-aminopropane, 1 - benzyloxy - 2 - dimethylaminoethane, N - methylmorpholine and 1 - (b - ethyl - hexoxy) - 3 - aminopropane. Among processes described in examples are those in which the 1 : -chromium complex of the azo dye 6 - nitro - 2 - hydroxy - 1 - amino - naphthalene - 4 - sulphonic acid --> 2 - hydroxynaphthalene is boiled with 1-(b -ethyl-hexoxy)-3-aminopropane in aqueous ethanol; 4-nitro-2-aminophenol - 6 - sulphonic acid --> 1 - phenyl-3 - methyl pyrazolone - (5) is reacted with 1 - (b - ethyl - hexoxy) - 3 - aminopropane in aqueous formic acid and 4-nitro-2-aminophenol - 6 - sulphonic acid in aqueous solution is reacted with 2-hydroxy-5-nitrobenz-aldehyde; the product is boiled with aqueous chromium chloride and the product is reacted with 1 - (b - ethylhexoxy) - 3 - amino propane in aqueous acetic acid solution. |
