pounds such as cellulose esters or ethers and in the products so Obtained.
Our invention relates to-the use of anthraquinone derivatives which have afiinity for cellulose compounds such as cellulose acetate, cellulose formate, ethyl cellulose, propyl cellulose or other organic cellulose esters and cellulose ethers. Especially suitable are watersoluble anthraquinone derivatives, for example, alkaline earth metal salts such as the sodium salts. For the purpose of this invention we will call these cellulose deriva-' wrmging Washing and drying the Silk is tives organo-oxy-cellulose compounds.
We have now found that amino-anthraquinone-N-methyl w-sulfonic acid compounds are easily'absorbed by organo-oxy-cellulose compounds and that shades ranging ractically over the whole color scale can e obtained by dyeing organic cellulose esters and cellulose-ethers in aqueous solution with such products. This process is exceedingly valuable forobtaining fast and brilliant shades on textile products made out of such cellulose compounds and in so-called mixed goods it i .by the following examples, the parts being allows -to obtain various effects especially when the other textile fibres woven together with the cellulose ester or cellulose ethers have a different aflinity for these anthraquinone dyes. Y Y a The amino-anthraquinone-N-methyl-w-sulfonic acid compounds referred to are of the general type of 1-4-diamino-anthraquinone-N-methyl-msulfonic acid n-N-om-soma are dissolved in 10,000 parts hot water. 250 parts cellulose acetate silk are entered into this dye bath at about C. and treated for of an hour at this temperature. After dyed a clear bright violet.
Example 2.-Six parts of the sodium salt of 1-5-dihydroxyl-8-diamino-anthraqui none- I-methyl-w-sulfonic acid NE, on
n I n-onrsomn are dissolved in 10,000 parts of wat'er'and They are obtained by treating the correaqueous and eventually acid suspension.
Other substitution in the anthraquinone nucleus as for instance by hydroxyl groups though modifying the shade, will 'not influence the dyeing properties for organo-oxycellulose compounds.
Our invention will be further illustrated by weight Example 1.--Six parts of'the sodium salt NHI c are dissolved in 10,000 parts ofwater. 250 parts cellulose formate silk are dyed in this bath at about 70 C. for of an hour. A deep,,bright greenish-blue shade is obtained.
-In the same way beta-aminoanthraquinone- .N-methyl-m-sulfonic acid compounds'can beused.
We claim 2-- v 1. The process ofdyeing organo-oxy-cellulose compounds which consists in treating same with amino-anthraquinone-N-methyh lose compounds which consists in treating same with aqueous solutions of soluble amino-anthraquinone N methyl-m-sulfonic acid compounds.
3. The process of dyeing cellulose acetate which consists in treating same with aminoanthraquinone N1 methyl-m-sulfonic compounds.
4. The process of dyeing cellulose acetate which consists in treating same with aqueous solutions of soluble amino-anthraquinone-N methylw-sulfonic acid compounds.
5. The processof dyeing organo-oxy-cellulose compounds which consists in treating same with l--diamino-anthraquinone-N- methyl-w sulfonic acid compounds.
6. The process of dyeing organoony-cellulose compounds which consists in treating same with aqueous solutions of soluble salts of 1-4-diamino-anthraquinone-N-methyl-wsulfonic acids.
7. The process of dyeing cellulose acetate acid acids.
which consists in treating same with 1-4 diamino-anthraquinone-N-methyl-w-sulfonic acid compounds.
8. The process of dyeing cellulose acetate which consists in treating same with aqueous solutions of soluble salts of l-4-diaminoanthraquinone-N-methyl-w-sulfonic acids.
9. As new products organo-oxy-cellulose compounds dyed with amino-anthraquinone- N-methyl-w-sulfonic acid compounds.
10. As new products organo-oxy-cellulosc compounds dyed with soluble salts of L4- diamino-anthraquinone-N-methyl-w-sulfonic acids.
