The invention relates to the use of dyes of the general formula

Dyeing and printing of fiber goods
high molecular weight polyesters

O NH

wherein R denotes an optionally substituted, aliphatic carboxylic acid radical and that with Bz designated ring nor substituents such. B. alkyl, halogen, nitro, trifluoromethyl, acylamino, acyl, may contain and the condensation of the corresponding 1-amino - anthraquinone - 3,4 (N) - benzacridones with aliphatic carboxylic acids, which can also contain substituents, or the functional ones Derivatives of these acids, optionally in the presence of acid-binding agents, have been prepared are for dyeing and printing on polyester fiber materials.

The dyeing and printing of the polyester fiber materials with the inventively to be used » The dyes are done according to the methods known for this purpose, such as those used in textile practice. 1956, p. 692 to 697, especially p. 697, last paragraph, are published.

The dyes to be used according to the invention produce dyeings or prints with very good fastness properties, especially very good lightfastness.

Dyes obtained by acylation of 1-aminoanthraquinone-o'-chloro-S ^ fNJ-benzacridone obtained, and contain a butyryl or acetyl radical, have a when printing on polyester fabric greater color strength than the dye known from US Pat. No. 2,623,047, the acyl component contains a hexahydrobenzoyl radical.

The dyes described in the examples below were each obtained by acylating the corresponding 1-amino-anthraquinone-3,4 (N) -benzacridone produced.

example 1

A fabric made of polyethylene glycol terephthalate is padded on the padder with the following liquor:

Applicant:

Cassella Farbwerke Mainkur Aktiengesellschaft,

6000 Frankfurt-Fechenheim

Named as inventor:

Dr. Werner Zerweck t, 6000 Frankfurt;

Dr. Ernst Heinrich, 6000 Frankfurt-Fechenheim

9.0 g 1 n-butyrylamino-anthraquinone

3,4 (N) -benzacridone
989.0 grams of water

0.5 g of a polyglycol ether of oleyl alcohol, 1.5 g of polyacrylamide with a K value of 120

1000.0 g

After drying, it is fixed in the heat-setting frame at 215 ° C. for about 60 seconds and then post-treated as usual. A reddish blue dyeing with very good fastness properties is obtained in this way.

Dyeings of similar shades and also very good fastness properties are obtained, if in the above dyeing instructions the 1 n-butyrylamino - anthraquinone - 3,4 (N) - benzacridone is replaced is replaced by l-acetylamino-anthraquinone-3,4 (N) -benzacridone, l-propionylamino-anthraquinone-3,4 (N) -benzacridone, 1 - Valerylamino-anthraquinone-3,4 (N) -benzacridone, 1 -Capronylamino-anthraquinone-S ^ NJ-benzacridone, 1 -Caprylamino-anthraquinone-S ^ NJ-benzacridone or by 1-acryloylamino-anthraquinone-3,4 (N) -benzacridone.

Manufacture of the in paragraph 1 of this example
dye used

A mixture of 200 parts of monochlorobenzene, 34.0 Teilenl-amino-anthraquinone-3,4 (N) -benzacridon and 21.2 parts of n-butyric acid chloride is heated for 12 hours to 120 ⁰ C with stirring. After cooling, the resulting dye is filtered off with suction and washed first with monochlorobenzene and then with methanol and dried. The dark blue

809 618/526

Dye powder dissolves in concentrated sulfuric acid with a red-orange color.

Example 2

A fabric made of polyethylene glycol terephthalate is printed with the following printing paste:

30 g of l-zS-chloropropionylamino-anthraquinone-3,4 (N) -benzacridone

150 g of the sodium salt of a sulfonated castor oil

(about 50%)
210 g of water

600 g crystal rubber thickening (1: 3) 10 g defoamer

1000 g

After drying, further treatment is carried out as described in Example 1.

A reddish-tinged blue print with very good fastness properties is obtained.

If in the above example the l-zS-chloropropionylamino-anthraquinone-3,4 (N) -benzacridone replaced by l-chloroacetylammo-anthraquinone-3,4 (N) -benzacridone, the print is clearly more reddish blue Nuance and also obtained from very good fastness properties.

Claims (1)

Claim: Use of dyes of the general O NH-R formula wherein R denotes an optionally substituted, aliphatic carboxylic acid radical and the ring denoted by Bz may contain further substituents and the by condensation of the corresponding 1 - amino - anthraquinone - 3,4 (N) -benzacridones with aliphatic carboxylic acids, which may also contain substituents, or the functional derivatives of these acids, if appropriate in the presence of acid-binding agents, for dyeing and printing on polyester fiber materials.
