| titleOfInvention | PROCEDURE FOR PREPARING TRIAZOIC SULPHONE DYES. |
| abstract | Procedure for preparing sulfonated triazo dyes, included in the general formula: **(See formula)** where E is a benzene nucleus substituted with one or more substituents chosen from the group consisting of -OH and/or NRR1 (R and R1 being hydrogen, lower alcohol, hydroxyalkyl, alcohol-halogen, cyanalcohyl, having from 1 to 4 atoms carbon), halogen, NO2, lower alcohol groups optionally substituted by OH, halogen, CN or lower alkoxy, or acylamino groups having 1 to 4 carbon atoms; Z is the radical of a sulfonated coupling bis-aminonaphthol; A is a benzene core optionally substituted by NO2, -SO3H, halogen, or lower acylamino having 1 to 3 carbon atoms; X is H, an alcoholic having 1 to 3 carbon atoms, an alkoxy having 1 to 3 carbon atoms, or a halogen, characterized in that, working according to the technique, p, p'-diaminobenzanilide is optionally tetraazotized substituted, a bis-amino coupling-naphthol-disulfonic acid is coupled with the tetrazoic derivative in an acidic medium, the resulting monoazo compound is coupled with the diazo compound of aniline or a substituted aniline, and finally the diazoic group of the disazo compound thus obtained is coupled with a compound selected from those represented by the symbol E in the general formula.
