use	mainly used as primer for cotton fiber dyeing and printing tryptopol AS-VL is often mixed with tryptopol AS for cotton cloth dyeing and backing. Medium affinity to cotton and medium coupling ability. The performance is similar to that of tryptopol AS-RL. It is also used for viscose fiber dyeing and cotton printing.
production method	using 2,3-acid and p-ethoxyaniline as raw materials, first 2,3-acid and sodium carbonate are formed into sodium salt in chlorobenzene medium, and fully dehydrated, then condensed with p-ethoxyaniline in the presence of PCl3, neutralized, distilled, filtered and dried to obtain the finished product..
