| titleOfInvention | Process for the preparation of water-insoluble azo dyes on the fiber: impregnating with coupling component and treating with diazonium salt of 4-chloro-2,5-dialkoxy aniline |
| abstract | According to the procedures of the ice color dyeing technique, fiber materials, such as, for example, cellulose fiber materials, are dyed by coupling the fiber material bottomed with a coupling component in an aqueous medium with the diazonium compound of an aniline compound of the general formula (1) mentioned and defined below, the coupling reaction and dye formation on the fiber being carried out at a pH between 3 and 10 ##STR1## in which R stands for a straight-chain or branched alkyl group of 3 or 4 carbon atoms. |
