Abstract
A dye of the formula <FORM:1078227/C4-C5/1> is prepared by reacting 2,5-dimethyl thiadiazole with propane sultone and diphenyl formamidine and condensing the product with 1,3-dimethyl hydantoin. A dye of the formula <FORM:1078227/C4-C5/2> is prepared by reacting 1-methyl-2-methylmercapto-5, 6-dichlorobenzimidazole with propane sultone and condensing the product with 3-ethyl-5-ethylidene rhodanine. The dye of formula <FORM:1078227/C4-C5/3> is prepared by diazotizing 3,31-diethoxy-4,41 -diamino diphenyl and coupling with 1-(p-toluene sulphonyl amino)-8-hydroxy naphthalene-3,6-disulphonic acid.
