s-トリアジン型および尿素型アゾ染料に関する研究

New dyes were synthesized from condensation of 2, 4, 6-trichloro-s-triazine and aminoazo dye or with hydroxyalkyalmine or bis(hydroxyalkyl)amine, having alcoholic hydroxyl as a functional group other than amino group, such as 2-aminoethanol or 2, 2′-iminodiethanol. Dyeing and fastness characteristics of dyes obtained by urein binding of the same aminoazo dyes were compared. As aminoazo dyes, 4-amino-2 2′-dimethY1-1 4′-1′, 4′′-1′′ 4′′′-trisazobenzene-1′′′, 3′′-disulfonic acid, 2-(4′-amino-2′-methylphenylazo)naphthalene-4, 8-disulfonic acid, 4-amino-3-methoxy-1, 1′-azobe nze-3′-sulfonic acid, and 1-amino-4, 1′-azo-4′-hydroxybenzene-3′-earboxylic acid, have been used. Dyes having 2, 4-dichloro-6-alkanolamino-s-triazine nucleus showed higher solubility in water due to the presence of hydrophilic residual alkanolamine group and showed better fastness against various tests than those of dyes from urein binding, especially, it showed no discoloration by the dyeing at high temperature.
