Abstract

970,936. Reactive disperse dyes. SANDOZ Ltd. Oct. 20, 1960 [Oct. 23, 1959], No. 36031/60. Heading C4P. The invention comprises disperse dyes free from water-solubilizing groups which dyes contain at least one triazine ring attached to the dyestuff radical through an oxygen atom and which triazine ring contains at least one chlorine or bromine atom. The dyes are prepared by condensing disperse dyes containing at least one hydroxy group with a di- or tri-halotriazine. Diazo or coupling components containing hydroxy groups may be similarly reacted and subsequently converted by the coupling reaction into azo dyes. Dyes containing two halogen atoms on the triazine ring may be further reacted e.g. with an amine to replace one of the halogen atoms. The dyes may be used to dye, pad or print hydrophobic fibres e.g. polyamide, polyester, polyacrylonitrile, polyurethane, polyvinyl chloride and cellulose acetate fibres, preferably with heating and in the presence of acid-binding agents. In examples the preparation of mono- and dis-azo, anthraquinone and nitro dyes is specified.
