where R is optionally substituted by halogen, alkyl, alkoxy, a trifluoromethyl or nitro group Phenyl nucleus and R 'denotes cyano or halogen is used.

The dyes mentioned can be obtained in a known manner, for. B. by implementing l-acylamino ^ -halogen-anthraquinones with accordingly substituted anilines or by condensation of l-amino-4-halo-anthraquinone-2-sulfonic acids with suitable anilines, elimination of the sulfonic acid group in the 2-position and acylation of the resulting 1-amino-4-arylamino-anthraquinones.

The strongly colored prints or dyeings which can be produced according to the invention on polyester fiber materials have very good fastness properties, in particular excellent heat-setting and lightfastness.

Compared to printing on polyester fabric with that known from German Patent 1,037,406 Possess l-amino-2-nitro-4-butyryl-aminoanthraquinone Prints with the l-benzoylamino-4- (m-chloro-anilido) -anthraquinone to be used according to the invention a superior hot air fixation fastness.

example 1

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

25 g l-Benzoylaroino-4- (in-chloro-anilido) -

anthraquinone,
150 g of the sodium salt of a sulfonated castor oil

(about 50 ° / _o solution),
215 g water,

600 g crystal rubber thickening (1: 3),
IQg defoamer,

1000 g.

ao After drying, fixation is carried out for about 60 seconds at 200 ^J C in the thermonxing frame. It is then rinsed and then in a solution that

3 ccm / 1 sodium hydroxide solution 38 "Be \
2 g / l hydrosulfite conc. PIv.,
^a5 1 g / l polyvinylpyrrolidone

contains, treated for about 15 minutes at 60 to 70 "C. It is then rinsed well, with about 2 g / l a non-ionic detergent soaped, rinsed and dried. A full blue-violet print with very good fastness properties is obtained. Prints of a similar shade and also of very good fastness properties are obtained, if in the above printing specification the 1-benzoylamino-4- (m-chloro-anilido) -anthraquinone is replaced by 1 - Benzoylatnino - 4 - (ra - brom - anilido) - anthraquinone, l- (m-Toluylamino) -4- (m-chloro-anilido) -anthraquinone, l- (m-methoxy-benzoylamino) -4- (m-chloroanilido) -anthraquinone, l-Benzoylamino-4- (o-chloroanilido) - anthraquinone, 1 - (p chloro - benzoylamino) -4- (o-chloro-anilido) -anthraquinone, 1 - (m-Trifluoromethylbenzoylamino) -4- (o-chloro-anilido) -anthraquinone or by l- (m-nitro-benzoylamino) -4- (o-chloro-anilido) - | anthraquinone. On the other hand, there are reddish blue prints obtained when using l-benzoylamino-4- (pchlor - anilido) - anthraquinone, 1 - (m - toluylamino) -4- (p-chloro-anilido) -anthraquinone or from l- (m-methoxy - benzoylamino) - 4 - (p - chloro - anilido) - anthrac hiiion and blue-gray prints when using l- (p-nitro- jj

benzoylamino) -4- (m-chloro-anilido) -anthraquinone and Λ of l- (p-nitro-benzoylamino) -4- (p-chloro-anilido) - f anthraquinone.

Example 2

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

25 g l-ßenzoylamino-4-0n-cyano-anilido) -

anthraquinone,
875 g water, ■
100 g crystal rubber thickening (1: 3),

1000 g.

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

A blue-violet coloration - more reddish than that of Example 1 - with very good fastness properties is obtained.

Dyeings of a similar shade and also very good fastness properties are obtained if in the above procedure the 1 -BenzoyIamino-4- (m-cyananilido) -anthraquinone is replaced by l- (m-Toluylamino) -4- (m-cyano-am'lido) -anthraquinone or by 1 - (m - methoxy - benzoylamino) - 4 - (m - cyano - an i lido) anthraquinone.

Example 3

A fabric made of polyethylene glycol terephthalate is padded on the padder with the following liquor: ² ^ 25 g l-Bcnzoylainino-4- (m-chloro-anilido) -

anthraquinone,
973 g water,

0.5 g of a polyglycol ether,
1.5 g polyacrylamide,

1000 g.

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

A blue-violet coloration with very good fastness properties is obtained.
