An alternative to your Lanaset Black B is Irgalan Black RBLN
(Ciba-Geigy) for dyeing silk, wool and polyamid fibres, fulfilling
the requirements you are looking for.

There is a website by Ciba-Geigy which gives you a lot of
information on all sorts of dyestuffs and where you even can place a
sample request: <URL:http://www.cibasc.com/pf/>  (Textiles and
Fibers etc.)
