The subject of patent 1,223,797 is the use of derivatives of 1-aminoanthraquinone the formula

O NH ₂

where Y represents a hydrogen atom, a methyl group, a methoxyl group or a halogen atom such as Chlorine or bromine atom, is available as dyes for dyeing and / or printing of structures linear polyesters.

As a further development of the subject matter of the main patent, it was found that as dyes can also use those derivatives of 1-aminoanthraquinone that are in 5- or 8-position of the anthraquinone nucleus carry the aromatic thioether residue.

Dyes of the general formula are of particular technical interest

O NH ₂

O R

and

in which R represents a hydrogen atom or a hydroxyl group and Y represents a hydrogen atom, a Methyl group, a methoxyl group, a hydroxyl group or a halogen atom such as a chlorine or Bromine atom, stands.

Such dyes can be appropriately substituted by reaction in a manner known per se 1-Aminohalogenanthraquinones with aryl mercaptans

Dyeing and / or printing of structures
made of linear polyesters

Addendum to the patent: 1 223 797

in organic solvents and in the presence of alkaline agents.

The dyes used in accordance with the invention, which are those described in the main patent specification Methods that can be used produce colorations and prints that are characterized by very good light and light Distinguish wet fastness properties. They are also very resistant to thermal loads, as they occur, for example, during so-called heat setting.

Mixtures of the abovementioned dyes with one another or with other dyes can also be used be used.

The parts and percentages given in the examples are units of weight.

example 1

100 parts of polyethylene glycol terephthalate fabric are dyed for 90 minutes at boiling temperature in a bath consisting of 1 part of finely divided l-amino-5-phenylmercaptoanthraquinone, 4 parts of finely divided 2-hydroxydiphenyl and 3000 parts of water. After vigorous rinsing treating the fabric in a bath consisting of a solution of 3 parts of about 32 ° / aqueous sodium hydroxide solution cent and 3 parts of sodium dithionite in 3000 parts of water, for 15 minutes at 8O ⁰ C.

Brilliant orange colorations of very good lightfastness and good thermal stability are obtained.

If you use dye baths that are the same instead of l-amino-5-phenylmercaptoanthraquinone

709 718/402

Quantity 1 - amino - 5 - (ο - tolylmercapto) - anthraquinone or l-amino-S-ip-tolylmercaptoi-anthraquinone contain orange dyeings with good fastness properties.

Example 2

100 parts of polyethylene glycol terephthalate threads are dyed in a bath containing, in 1500 parts of water, 0.6 part of finely divided l-amino-5- (p-methoxyphenylmercapto) anthraquinone and 2 parts of a product which is obtained by reacting 1 mol of sperm oil alcohol with 80 mol Ethylene oxide and subsequent sulfation has received, 1 hour at 130 ⁰ C under pressure.

The threads are in brilliant orange tones with very good light and thermosetting fastness colored.

If you use dyebaths that contain l-amino-5- (p-methoxyphenylmercapto) anthraquinone in place of 0.6 parts 0.4 parts of 1-amino-4-hydroxy-5-phenylmercaptoanthraquinone are obtained Bordo dyeings with very good lightfastness, good washfastness and very good thermal resistance.

Example 3

Polyethylene glycol terephthalate fabric is printed with a paste containing 20 parts in 1000 parts

l-Ammo-S-phenylmercaptoanthraquinone, 600 parts a gum arabic thickener, 30 parts of 4-hydroxydiphenyl and 350 parts of water. Then the printed fabric is dried and at 1.5 atm for 15 minutes. Overpressure dampened. You get brilliant, orange-colored prints of good lightfastness and good thermal resistance.

Example 4

100 parts of polyethylene glycol terephthalate fibers are in a bath consisting of! Parts finely divided

1 - amino - 8 - (ρ - chlorphenylmercapto) - anthraquinone,

2 parts of the product obtainable by reacting 1 mole of sperm oil alcohol with 80 moles of ethylene oxide and subsequent sulfation and 2000 parts of water, colored in a pressure ^{vessel at 125 ° C. for one hour.} Strong orange colorations of good lightfastness and good thermal stability are obtained.

Claims (1)

Claim: Use of derivatives of 1-aminoanthraquinone, which carry the aromatic thioether radical in the 5- or 8-position, according to patent 1 223 797 for dyeing or printing structures made of linear polyesters. When the application was announced, a coloring table was displayed. 709 718/402 12.67 © Bundesdruckerei Berlin
