Results on affinity measurements and paper chromatography of some anionic azo dyes, obtained by diazotization of 4‐aminobenzophenone, 2(4′‐amino‐benzoyl)thiophene, 4′‐aminobenzanilide, 2‐thiophene‐carboxanilide‐4′‐amino, trans‐4‐aminostilbene and trans‐2(4′‐aminostyryl)thiophene and coupling with naphthionic acid, Nevile‐Winther's acid, R acid, Hacid and chromotropic acid, have been reported. A linear relationship between the R m value of the dyes and their standard affinity of dyeing has been observed for dyes with the same coupling component.
