Abstract
The applications of ethyleneimine derivatives to dyestuffs were investigated, and useful reactive dyestuffs were synthesized. Introducing aziridinyl groups into dyestuff molecules makes generally the dyestuff insoluble in water. In dyeing, textile fabrics are padded in the dyestuff suspension and then heat-treated. The fastness of the dyestuff is appreciably improved and the color is not changed. Copper phthalocyanine dye was chlorosulfonated and then reacted with ethyleneimine to give di- and tetra-substituted compounds. The tetra-aziridinyl compound is insoluble in water.The di-aziridinyl compound, however, was made soluble in water by changing the remaining two sulf ochloride groups into sodium sulf ovate groups. The dyestuff thus modified has partially the properties of acid dye, and can uniformly dye not only cotton but wool, nylon and polyacry lonitrile fabrics in the usual method of dyeing. The color of the dye was very bright blue and the fastness was the highest.
