It has been found that deep dyeings or deep prints on polyester fiber materials, in particular those based on polyethylene glycol terephthalates, obtained if dyes are used for dyeing or printing by the thermofixing process the general formula

used, in which R is a salicylic acid radical optionally substituted by halogen, alkyl or alkoxy, which can also contain a fused-on benzene ring, and X and Y are hydrogen or halogen.

The dyes mentioned can be obtained in a known manner by condensation of ¹ 1-amino-anthraquinone with corresponding substituted salicylic acids or their functional derivatives.

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 very good heat-setting and lightfastness.

The dyes to be used according to the invention 1 - salicylamino - anthraquinone and 1 - (Γ - hydroxy-2'-naphthoylamino) anthraquinone stand out when printing on polyester fabric using the thermosetting process compared to 1-benzoylaminoanthraquinone and l- (a-naphthoylamino) anthraquinone, whose use as polyester dyes is known, are characterized by their superior lightfastness.

example 1

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

25 g l-salicylamino-anthraquinone,
150 g of the sodium salt of a sulfonated castor oil

(about 500 / oig),
215 g water,
600 g crystal rubber thickening (1: 3),

10 g Ent-seHäjBBiefr
1000 g iiU

Process for printing and dyeing
Fiber material made from high molecular weight polyesters

Named as inventor:

Dr. Werner Zerweck t, 6000 Frankfurt;

Dr. Ernst Heinrich, 6000 Frankfurt-Fechenheim

After drying, it is fixed in the heat-setting frame ^{at 200 ° C. for about 60 seconds.} It is then rinsed and then in a solution that

3 ccm / 1 sodium hydroxide solution, 38 ° Be,

2 g / l hydrosulfite, concentrated powder,

1 g / l polyvinylpyrrolidone

contains, treated at 60 to 70 ^{0 C for about 15 minutes.} This is followed by a good rinse, hot soapy with about 2 g / l of a non-ionic detergent, rinsing and drying. A greenish yellow 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-salicylamino-anthraquinone is replaced by l- (3'-methylsalicylamino) - anthraquinone, 1 - (4 '- methyl - salicylamino) - anthraquinone, 1 - (5 '- chloro - salicylamino) anthraquinone, 1 - (5' - bromine - salicylamino) - anthraquinone, 1 - (4 '- methoxysalicylamino) - anthraquinone, 1 - salicylamino - 6 - chloro - anthraquinone, 1 - salicylamino - 7 - chlorine - anthraquinone and 1 - salicylamino-6,7-dichloroanthraquinone.

In contrast, a reddish-tinged yellow print is obtained when using 1- (5'-methoxysalicylmino) anthraquinone. ;

Eg game, 6 "<£ /

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

25 g 1 - (Γ - hydroxy - 2 '- naphthoylamino) - anthraquinone,
973 g water,

0.5 g of an ethylene oxide product,
1.5 g polyacrylamide.
1000 g

809 520/635

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

A reddish yellow coloration with very good fastness properties is obtained.

Dyes of a similar shade and also very good fastness properties are obtained, if in the above procedure the 1- (1'-hydroxy-2'-naphthoylamino) anthraquinone is replaced by - (Γ - Hydroxy - 4 '- chloro - 2' - naphthoylamino) - anthraquinone or by 1- (Γ-hydroxy-4'-bromo-2'-naphthoylamino) anthraquinone.

Claims (1)

Claim: Process for dyeing and printing fiber material made from high molecular weight polyesters, in particular those based on polyethylene glycol terephthalates, after the thermosetting process, characterized in that this dyes of the general formula NH-R used, in which R is a salicylic acid radical optionally substituted by halogen, alkyl or alkoxy, which can also contain a fused-on benzene ring, and X and Y are hydrogen or halogen.
