| titleOfInvention | New water-soluble reactive dyes of the anthraquinone series and their production |
| abstract | The invention comprises water-soluble dyes of the formula <FORM:0990269/C4-C5/1> in which R is a benzene radical having attached by way of nitrogen a group capable of reacting with hydroxyl groups of cellulose to form a covalent bond and which benzene radical may have further substituents. Groups reactive with cellulose are listed and include chlorotriazinyl and acrylyl groups and propionyl groups substituted in beta position by chlorine, phenylsulphonyl and dichloropyridazonyl groups. The dyes are made by reacting an aminothiophenol with an acylating agent and then with 1-amino-4-bromoanthraquinone-2-sulphonic acid, or by reacting the latter with the aminothiophenol and then, if desired, after sulphonation, with the acylating agent, the acylating agent in each case containing the group reactive with cellulose. The dyes dye and print textile materials of cellulose and natural or synthetic polyamides in violet shades. Specification 867,571 is referred to. |
