    Abstract: Dye formulation contains red reactive dye(s) (I), blue reactive dye(s) (II) and polyethylene-imine (III) with a mol.wt. of 1000-10000000. Also claimed is an ink for ink jet printing contg. this formulation. Pref. the formulation contains 80-96, esp. 84-94 pts.wt. (I), 3-8, esp. 3.5-6 pts.wt. (II) and 1-30, esp. 2-20 pts.wt. (III). (I) is azo dye(s), esp. 1-hydroxy-2-(2-sulpho-p-tolyl-azo)-8-(4-N-methyl-anilino-6- chloro-1,3,5-triazin-2-yl-amino)-naphthalene-3,6-disulphonic acid (IA); and (II) is anthraquinone dye(s), esp. 1-amino-4-(3-(4-(3-sulphoanilino)-6-chloro-1,3,5-triazin-2- ylamino)-2,4,6-trimethyl-5-sulpho-anilino)-anthraquinone-2- sulphonic acid (IIA). (II) has a mol.wt. of 1500-3000 or 600000-1000000 or 20000-25000.
