3-Amino-4-Methoxy Benzanilide(Red KD Base) (DB-40) |
The red KD base, 3-amino-4-methoxy benzanilide, produced by our works, is made from 3-niro-4-methoxy benzoic acid by processes of condensation with ammonia and reduction. It is a developer with higher fastness among ice dyestuffs and mainly used for printing of cotton, staple fibre and yarn of ramie, flax, etc. In the fields of dyeing, manufacturing of organic pigments, coloring of printing ink and coating printing-paste, it also finds application.
