Which Lanaset dye colors are pure, rather than mixtures?

See also "About Lanaset Dyes" and "Dyes for Protein Fibers" .

Note: The information on this page is intended to serve as an overview. There may be inaccuracies in the information. Please confirm data with your dye supplier before purchase. Ask your dye supplier to give you lightfastness and/or washfastness ratings for each of the dyes you are interested in.

Lanaset dyes are sometimes listed as "non-Colour Index dyes", but some of them do appear to have CI names, as given in the table below. The dye names and CI names were obtained from MSDS info at the School of Life and Environmental Sciences at Deakin University in Australia and from http://www.freepatentsonline.com/4553975.html.
