| 摘要 |
The invention comprises water-soluble anthraquinone dyes of the formula A-(NHCOCH2-CH2-OX)n where A is an anthraquinone dye radical, X is hydrogen or the radical of a carboxylic acid, of sulphuric acid or phosphoric acid and n is 1 or 2, and in particular dyes of the formula <f1> where Y is hydrogen or a sulphonic acid group, Z is a direct linkage or one of the radicals -CH2CH2-NH-, <f2> and X has the meaning given above. The dyes are made by reacting an anthraquinone of the formula A1-(NH2)n where A1 is an anthraquinone dye radical and n is as above, with a compound of the formula Cl-CO-CH2CH2-OR or by reacting an anthraquinone derivative containing sulphonic acid halide groups with aromatic or heterocyclic amines containing beta-hydroxypropionic acid amide groups or esterified beta-hydroxypropionic acid amide groups. When the products contain carboxylic acid ester groups they may be hydrolysed to the hydroxy derivatives which may then be exterified with a carboxylic acid or sulphuric or phosphoric acid. Examples are given. The dyes dye and print textile materials and shaped articles of wool, silk, synthetic linear polyamides and polyurethanes, cellulose and leather.
