DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Section cross-reference(s): 28 Yellow cationic dyes of structure I or II, where R is alkyl or aralkyl optionally bearing nondissocg. substituents, R1 is optionally substituted alkyl or aralkyl, R2 is H, lower alkyl, or halogen, and X- is an anion, are prepd. by alkylating the coupling product of a diazotized R-substituted 3-amino-1,2,4-triazole and R2-substituted 2-benzimidazoleacetic acid. Thus, 3-amino-1,2,4-triazole was diazotized and coupled with 2-benzimidazoleacetic acid, and the coupling product alkylated with Me2SO4 in sulfolane contg.
