<p>Continuous dyeing of polyester textiles. Dyes: (where R is H or CH3; X is O or NH and R1 is (CH2)3OCH2OC(CH3)3, (CH2)3OCH3, CH(CH3)-CHOHCH3 or CH2CHOHCH2CH3) are used for continuously dyeing polyester textiles in solvents, pref. trichlorethylene. In example, blue fast shades are obtained with (a) (I) where X is NH, R1 is (CH2)3OCH2OC4H9; (b) X is = O and R1 is (CH2/3OCH3.) Process can be carried out reliably as speck formation by pptn. is prevented.</p> |
