摘要： Method of coloring a synthetic or semisynthetic organic high molecular weight material with a asymmetric thioindigoid compound having the formula ##SPC1##Wherein R.sub.1, R.sub.2 and R.sub.3 may be the same or different and are selected from the group consisting of a hydrogen atom, chlorine atom, lower alkyl group, lower alkoxy group, cyclohexyl group, phenyl group, benzyl group and styryl group, the benzene nucleus of the phenyl and benzyl group may be optionally substituted with a methyl group or chlorine atom, R.sub.1 and R.sub.2 may together form a tetramethylene ring, R.sub.4 is a hydrogen atom or methyl group with the proviso that R.sub.4 is a methyl group when R.sub.1, R.sub.2 and R.sub.3 are each a hydrogen atom and R.sub.4 is a hydrogen atom when R.sub.1 is a methyl group and R.sub.2 and R.sub.3 are each a hydrogen atom. The colored organic high molecular weight materials exhibit brilliant nuance with characteristic fluorescence.
摘要翻译：用合成或半合成有机高分子量材料与具有式WHEREIN R1，R2和R3的不对称硫靛类化合物着色的方法可以相同或不同，并且选自氢原子，氯原子，低级烷基，低级烷氧基，环己基，苯基，苄基和苯乙烯基，苯基和苄基的苯核可以任选被甲基或氯原子取代，R 1和R 2可以一起形成四氢环，R 4是氢原子或甲基，条件是当R1，R2和R3各自为氢原子时R4为甲基，当R1为甲基时R4为氢原子，R2和R3分别为氢原子。有色有机高分子材料表现出辉煌的特征荧光。
