A new series of pink to violet fluorinated aminoanthraquinone dyes for cellulose acetate, having in some cases enhanced fastness to light and gas, was prepared by replacing one OH group of quinizarin with a fluoroalkylamino group. Fluoroalkylamine intermediates, which were prepared by the reaction of fluoroalkyl halides with NH4OH, include 2,2,2-trifluoroethylamine, b. 35-6¡ã, 2,2-difluoroethylamine, b. 68-9¡ã, 2,2,2′,2′-tetrafluorodiethylamine, b. 122-3¡ã, 3,3-difluoropropylamine, b. 92-4¡ã, nD20 1.3650, 3,3,3′,3′-tetrafluorodipropylamine, b50 91-4¡ã, nD20 1.3744, 2,2-difluoropropylamine, b. 76-7¡ã, nD25 1.3622, 2,2,2-trifluoro-1-methylethylamine, b. 46-7¡ã, nD20 1.3210, 3,3,3-trifluoropropylamine, b. 67¡ã, nD20 1.3316, and 4,4-difluoropentylamine, b. 125-30¡ã, nD25 1.3864. The dyes which were prepared include 1-hydroxy-4-(2,2,2-trifluoroethylamino)anthraquinone, m. 158-60¡ã, 1-(2,2-difluoroethylamino)-4-hydroxyanthraquinone, m. 141-2¡ã, 1,4-bis(2,2-difluoroethylamino)anthraquinone, m. 242-3¡ã, 1-(2,2-difluoropropylamino)-4-hydroxyanthraquinone, m. 135-8, 1-hydroxy-4-(2,2,2-trifluoro-1-methylethylamino)anthraquinone, m. 143-5¡ã, 1-(3,3-difluoropropylamino)-4-hydroxyanthraquinone, and 1-(4,4-difluoropentylamino)-4-hydroxyanthraquinone, m. 128-30¡ã. Another series of dyes can be prepared by the reaction of 1-amino-4-bromo-2-trifluoromethylanthraquinone with a series of o-and p-(hydroxypolyethoxy)anilines. These dye cellulose acetate bright-blue shades and have excellent light-fastness and good resistance to gas fading. Intermediates prepared for this series include 1-chloro-2-methylanthraquinone, m. 158-9.5¡ã, 1-chloro-2-trichloromethylanthraquinone, m. 203-5¡ã, 1-chloro-2-trifluoromethylanthraquinone, m. 208¡ã, 1-amino-2-trifluoromethylanthraquinone, m. 144-6¡ã, and 1-amino-4-bromo-2-trifluoromethylanthraquinone, m. 175-7¡ã. The dye which was prepared was 1-amino-4-{p-{2-{2-[2-(2-hydroxyethoxy)ethoxy]ethoxy}ethoxy}anilino}-2-trifluoro-methylanthraquinone, m. 110-15¡ã.
