Abstract
The synthesis of 4,5-, 4,6-, 4,7- and 5,7-dichloro-2-aminobenzothiazol es is reported. Diazotisation of these and coupling to N-substituted a nilines affords orange-red to blue dyes which have excellent coloratio n and good light fastness properties on polyester. The colour of the d yes is discussed with respect to the orientation of the chloro substit uents and compared also with dichloro-4-aminoazobenzene analogues and to established colorants based on 5,6(6,7)-dichloro-2-aminobenzothiazo le.
