본 발명은 물에 분산되고 녹색 식물로부터 얻어진 폴리에스테르 패브릭을 염색하기 위한 생체적합하고 생분해가능한 천연 분산 염료에 관한 것이다. 분산 염료는 Mg-클로로필린으로부터의 산 또는 Cu-클로로필린으로부터의 산과 같은 산 클로로필린 유도체를 활성 염료 화합물로서 함유한다. 본 발명의 분산 염료는 0.01중량% 내지 20중량% 범위의 농도의 섬유(OWF)를 전형적인 방법에 의해 폴리에스테르 패브릭을 염색하고, 그에 따라서 90% 초과의 염료 소진의 조건하에 우수한 색 강도 및 광, 세척 및 러빙에 대한 우수한 견뢰도를 지니는 염색된 패브릭을 제공하기 위해 사용될 수 있다. The present invention is directed to a biocompatible and biodegradable natural disperse dye for dyeing polyester fabrics which is dispersed in water and derived from green plants. The disperse dye contains as the active dye compound an acid chlorophyllin derivative such as acid form Mg-chlorophyllin or acid form Cu-chlorophyllin. The disperse dye of the present invention can be used for the dyeing of polyester fabrics by traditional methods in concentrations ranging from 0.01% to 20% on weight of fibers (OWF), thus providing a dyed fabric with good color strength and good fastness to light, washing and rubbing, under conditions of dye exhaustion of greater than 90%.
