Anthraquinone dyes, which do not contain sulphonic acid groups, where Y is a direct bond or a bridge such as -O-, -S-, -NH-, or an alkylene chain with at most 12C atoms bound via one or more hetero atoms, such as -O-alkylene, -S-alkylene, -NH-alkylene, -O-alkylene-O-, -O-alkylene-S-, etc. or an acylamino or acylester groups, esp. a carboxylic acid ester or amide group or a sulphonic acid ester or amide group; R1-5 is H, halogen, NO2, NH2, NH-alkyl, N(alkyl)2, NH-aryl, OH, O-akly, O-aryl, -S-alkyl, -S-aryl, aryl groups and R1 = low alkyl group; R is (opt. further substituted) acylamino residue and m, n and p = 1-3. Especially useful for dyeing and printing polyester fibres. Good light resistance and resistance to sublimation. |
