Synthesis
4,5'-Bisbenzoylamino-1,1'-dianthrimide- 2,2'carbazole , Indanthren Brown R, is prepared from 4,5'-bisbenzoylamino- 1,1'-dianthrimide by ring closure in concentrated sulfuric acid .
Properties and Applications
brown. Deep red powder. Insoluble in water and Etanol, slightly soluble in Xylene for bordeaux red solution. In concentrated sulfuric acid for dark wine red, dilution to red light brown, flocks. Alkaline reduction leuco body for the color red; Acid reduction leuco for yellow brown. Is light brittle dye. To cotton affinity is poorer, less used in cotton dyeing. Suitable for direct printing, resist printing and aniline black color resist, also suitable for shallow, color of discharge. Suitable for cotton knits dyeing, more suitable for silk printing. But printing and dyeing fabric in sunlight exposure easy appear fiber brittle damage phenomenon. Can be used for viscose and wool dyeing, can also be processed into organic pigment.
