(I) are used for dyeing, slop pad dyeing or printing of synthetic textiles, esp. aromatic polyesters, opt. mixed with cellulose. (I) can also be used for dyeing polyamides. For polyester/cellulose textiles, (I) can be used in conjunction with reactive dyes. They are also suitable for bulk colouring of synthetic materials and for transfer printing.</p> |
