Beschreibung
Zusammenfassung:	Provided is a compound that has a high biomass degree (more preferably a compound that has a biomass degree of 100%) and that is obtained by utilizing a natural pigment, wherein the compound has exceptional color development properties and light resistance.　The present invention is a compound obtained by bonding a natural pigment of curcumin and an organic acid, wherein the compound has a number-average molecular weight (Mn) of 400-4,950. L'invention concerne un composé de niveau de biomasse élevé obtenu par mise en œuvre d'un colorant naturel (de préférence, un composé de niveau de biomasse égale à 100%). Plus précisément, l'invention fournit un composé excellent en termes de propriétés chromogènes et de résistance à la lumière.　Ce composé est constitué par liaison d'un colorant naturel de curcumine et d'un acide organique. La masse moléculaire moyenne en nombre (Mn) dudit composé est comprise entre ４００ et ４９５０. 天然色素を利用して得られるバイオマス度の高い化合物（より好ましくはバイオマス度１００％の化合物）であって、発色性及び耐光性に優れた化合物を提供する。　クルクミンの天然色素と有機酸とが結合してなる化合物であって、前記化合物の数平均分子量（Ｍｎ）が４００～４９５０である、化合物である。
