The newly-developed p-amino
benzamide, produced by our works, is made from p-nitro 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.
