Reactive dyes - contg triazine gp, for leather wool, silk, polyamides cotton, linen and rayon

摘要

Reactive dyes of formula (where X is (m)ethylamino or dimethylamino and Y is (di)chlorotriazinyl) are prepd. by (i) reacting in any sequence 1 mole of a cyanuric halide with 1 mole of 1-amino-8-hydroxynaphthalene-3,6-disulphonic acid, 1 mole of 1-amino-3-acetylaminobenzene and 1 mole of an amine HX, (ii) deacetylating the prod. (iii) acylating the free amino gp. with 1 mole of 2,4,6-trichlorotriazine or of 2,4-dichlorotriazine substd. in position 6, and (iv) coupling 1 mole of II with 1 mole of the diazo cpd. from 1-aminobenzene-2-sulphonic acid. The dyes are used for leather, wool, silk, synthetic polyamides, cotton, linen, rayon.
