PCT No. PCT/EP93/00426 Sec. 371 Date Sep. 2, 1994 Sec. 102(e) Date Sep. 2, 1994 PCT Filed Feb. 24, 1993 PCT Pub. No. WO93/18224 PCT Pub. Date Sep. 16, 1993. <IMAGE> (I) <IMAGE> (II) A process for the dyeing of cellulose-containing fibre materials with reactive dyes, which comprises carrying out dyeing in the presence of the salt of a mineral acid in an amount of 0 to 20 g per liter of dyebath and using at least one of the reactive dyes of formulae (I) and (II) in which the substituents are as defined in claim 1. This produces dyeings having good fastness properties in a high coloristic yield. Moreover, the addition of fairly large amounts of salts of a mineral acid, which is a common practice in dyeing, can be omitted. |
