Phenoxycarbonylalkyl-substd. dispersion dyes of formula (I) are new. In (I) F' = residue of a non-azo dispersion dye, and Y = 1-3C alkylene. Ring A opt. has 1 or 2 substits. selected from (i) 1 or 2 of halogen, alkyl and alkoxy; and (ii) one of CF3, OH, NO2, CHO, CN, thiocyanate; 1-4C alkylcarbonyl, 1-2C alkylcarbonyloxy, aminocarbonyl, 1-3C alkoxycarbonyl, (1-2C) alkoxy-(2-3C) alkoxycarbonyl, 1-4C acylamino and phenyl. USE/ADVANTAGE - The use of (I) is claimed for dyeing, pad-dyeing or printing of fibres or filaments (or derived materials) of (semi)synthetic hydrophobic organic polymers. (I) are esp. for dyeing aromatic polyester or cellulose 2 1/2 or triacetate, giving e.g. violet, greenish yellow, greenish blue, blue orange or luminescent red shades. The dyeing have good general fastness, esp. excellent thermomigration fastness, good fastness to light, thermofixing, sublimation and pleating, and excellent wet-fastness, esp. after permanent press finishing. In an example, 12 pts. 1-amino-4-hydroxyanthraquinone, 9 pts. 2-methoxyphenyl acrylate, 0.1 pts. ZnCl2 and 50 pts. glacial acetic acid were refluxed for 10 hrs. at 119-121 deg. C. Work-up gave 1-(2-(2-methoxyphenoxycarbonyl) -ethylamino)-4-hydroxyanthraquinone, which dyed polyester fibres violet with excellent fastness.
