I have trouble finding certain dyes for my research (mostly acid dyes). I have approached producers of textile dyes from various countries, but the C.I. I am looking for are extremely hard to find. Does anyone have recommendations for suppliers of rare dyes for research purposes (small quantities)?
Malgorzata
Do you have names/structuress of the dyes you are looking for?
Yes, I am looking for several acid blue dyes: anthraquinone (Acid Blue 23, 47), triarylmethane (Acid Blue 104, 109) and azine (Acid Blue 121), as well as some vat dyes in their solubilized form (leuco sulphuric esthers of the parent form) Solubilized Vat Blue 5 and 8.
Do search @ https://cn.bing.com/ Acid Blue 23, Acid Blue 47,
or Google search.
You can find information.
Good luck!
Thank you for your suggestions, bing does give different search results, but suppliers are nevertheless not reachable. Thank you anyways!
I did find something by bing in China, I could not get on google here. I just too busy to do a complete search for you, sorry!
向老师，非常感谢您的帮助，其实我已经联系了在中国的一些化工企业，问过该染料的价格可一直都没受到回复。可没关系，我慢慢会找办法，再次谢谢!
