Message: I am doing research on dyes. Last time when I accessed your website I saw chemical structures of some procion MX dyes. However I didn't download them at that time and decided to do so later. This time I could not get link to some of them. It would be great if you can provide me with chemical structures of the following dyes.
blue MX-2G
orange MX-2R
brown MX-GRN
yellow MX-8G
turquoise MX-G.
I am pretty sure that structures of the above dyes were there when went through your site last time. I have already purchased them. I can't proceed further unless I know the chemical formula.

There has been no change, since January 2000, in the page on the chemical structures of dichlorotriazine dyes on my web site. (This is in the FAQ section, under "procion dyes". You can also find any page in the FAQ by using the search function on my web site, or by using the box at the top of the FAQ page.)

Sorry, but I have never seen a structure for turquoise MX-G, nor, in fact, for any of the other dyes you list. I would love to, but the manufacturers are not required to make this information public, and I suppose that they don't want their competitors to have the information. Turquoise MX-G is reputed to contain a copper atom.
