헥실기 이상의 알킬치환기를 가지는 디아미노안트라퀴논계 청색 분산염료의 합성과 순수폴리프로필렌 섬유에 대한 염색성

Abstract

As a subsequent research of the previously reported<TEX>$^{9)}$</TEX>, a series of diaminoanthraquinoid blue dyes having hexyl, heptyl and octyl substituents were newly synthesized in order to investigate dyeability toward polypropylene fibers. As the length of alkyl groups introduced to the chromophore increased, the dyeability of the dyes toward polypropylene fibers also increased and then gradually decreased. From the result of dyeing, the hexyl-substituted dye showed the highest color strength and deep shade on pure polypropylene fibers. The good fastness rates to wash, rubbing and light were also obtained for all of the synthesized dyes.
