Jolly, V. S. published the artcileCyanine dyes Part 2, Recommanded Product: 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Oriental Journal of Chemistry (2001), 17(2), 275-278, database is CAplus.
4-[Bis(2-cyanoethyl)amino]-2-methoxybenzaldehyde and 4-[bis(2-cyanoethyl)amino]-2-ethoxybenzaldehyde (I) on reaction with a number of quaternized heterocyclic amines gave a series of highly colored and lustrous cyanine dyes. Potentialities of the dyes for dyeing cotton, wool, and silk were investigated. The dye obtained by condensation of Fischer’s base hydriodide with I dyed cotton, wool, and silk in a bright red shade resistant to washing. One of the dyes showed some photosensitive activity.
