The newly-developed 3-amino-4-chloro
benzamide,produced by our works, is made from 3-nitro-4-chloro benzoic
acid by processes of condensation with ammonia and reduction. It
is 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.
