Copper-containing azo-direct dyes are fast to light. We have hitherto prepared some of them. This time we prepared Chlorantine Fast Rubine RLL, the constitution of which had already been determined by Fierz-David and Matter, from 2-aminophenol-4-sulphonic acid (I) or 2-aminoanisol-4-sulphonic acid (I'), J-acid (II), cyanuric chloride (III) and aniline (IV) according to the following four courses;　A- or A'-course : 1st step. III is condensed with II and IV into 2,4-di-J-acid-6-phenylamino-1,3,5-triazine(VI).　2nd step. I or I' is diazotized and then coupled with VI to give disazodye(VIIa) or (VII'a) respectively.　3rd step. VIIa or VII'a is treated with copper compound to convert into Chlorantine Fast Rubine RLL.　B- or B'-course : 1st step. I or I' is diazotized and then coupled with J-acid to give monoazodye(V) or (V') respectively.　2nd step. III is condensed with V or V' and IV into disazodye(VIIb) or (VII'b) respectively.　3rd step. VII'b is treated with copper compound to convert in to Chlorantine Fast Rubine RLL.　From the results of this experiment, the following conclusion was obtained;　1) A- and A'-courses are better than B- and B'-courses.　2) I' is better as diazocomponent than I..
