Abstract

The present invention relates to a reactive black dye composition comprising the following general formula (I), (II) and (III) compounds and to a process for preparing the same. The dye composition of the present invention is a high-concentration liquid dye excellent in solubility and washing fastness, and is particularly suitable for dyeing cellulose-based fibers.

Wherein R 1 and R 2 are each hydrogen, alkyl or alkoxy, and X represents -CH 2 CH 2 OSO 3 H or -CH = CH 2 .

Description
