PRIORITY: CH 76-9832 2 Aug 1976. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Hexakisazo compds. (I, R = H, SO3M, R1, R2 = OH, NH2; R3 = H, Me, SO3M; M = H, or colorless cation; Z = CH:CH) were prepd. and were used to dye paper fast gray and black shades.Several reagents such as 96-75-3 is used here. Thus, 1-amino-4-nitrobenzene-2-sulfonic acid [96-75-3] was diazotized, coupled with 1-amino-8-hydroxy-3,6-naphthalenedisulfonic acid [90-20-0], the resulting nitroazo compd. reduced with Na2S, the aminoazo compd. [66209-90-3] isolated, coupled with tetrazotized 4,4'-diaminostilbene-2,2'-disulfonic acid [81-11-8], the tetrakis azo compd. [66209-91-4] isolated by treatment with HCl, tetrazotized, and coupled with 1,3-phenylenediamine [108-45-2] to give I (R = SO3Na, R1 = R2 = NH2, R3 = H, NaO3S groups in 3- and 6-position, M = Na, Z = CH:CH) [66209-92-5]. .
