Abstract: Method of coloring a synthetic or semisynthetic organic high molecular weight material with a asymmetric thioindigoid compound having the formula WHEREIN R1, R2 and R3 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, R1 and R2 may together form a tetramethylene ring, R4 is a hydrogen atom or methyl group with the proviso that R4 is a methyl group when R1, R2 and R3 are each a hydrogen atom and R4 is a hydrogen atom when R1 is a methyl group and R2 and R3 are each a hydrogen atom. The colored organic high molecular weight materials exhibit brilliant nuance with characteristic fluorescence.
