10 Claim.

This invention'relates to a new type of dyeing and printing assistant, dyecomposltions containing these assistants and products printed therefrom.

Use of printing-color pastes containing dyes,

(Cl. 8-" factlire of the paste is not only 'tion they are thus generally more uniformly dispersed throughout a printing-color paste made particularly-in printing operations using vat dyes. is'sumciently well-knownso that the procedure v become almost standardized. The actual color 'source may be. either a dye paste or a dye powder;

Iniddltion to the real color, a dyepaste usually contains agents to prevent drying-out, settling and/or Dye powders, not being subject to,v these difficulties, do not require these agents.

but they contain 88ents or are so proces'sedas to promote dispcrsibility.

.In either case, the dyepaste or dye powder must be admixed with suitable thickener, usually therefrom. As a result, the printing assistants usually operate more effectively when the printing-color pastels finally applied to the fabric.

It is only relatively recently that dye powders suitable for use in making up printing-color pastes have been available. Most of the printing aids previously used in dye pastes, being either liquid in form or extremely hydroscopic, can not be used with dye powders, the latter being necessarily a sum dispersion, to forms printing-color paste a which is, suitable for application. In the case of vatdyes, it is also to add a reducing agent-and usually an alkali. Becausethecolor yield from printing-color pastes often decreases rapidly as the paste ages after being made up,

the'ae printing-,color pastes are usually p epared by the fabric finishers just before they are to be 7 e, printlngscolor pastes, however compounded, are then applied to textile. paper or other fabric materials .for decorative or protective purposes. The printed pieces are dried, agedin a steam ager, treatedwith' anoxidizing agent, rinsed and finally dried." Usually in'processing textiles,- printed fabric alsogis soaped at or near the "boil with about a 0.1% soap solution and a ain rinsed before the final dryinsr p ration,

In making up and applying printing-.color'pastes it has been found that a material suitable for use as a printing assistant is of advantage in obtainin: maximum color yield. .lhe exact way in which these act to produee'an improved color yield in printing is not entirely understood. It is with these printing aids or assistants that the present invention is particularly concerned.

Although printing aids are desimble in the 'printing-eolorpastes, the exact point at which they areadded may Dye pastes may contain printing-aids as one of their components and tins-color. made therefrom obviously contain the'printing assistant. Where a printing assistant is not present in the dye paste,

limited to the use of dry solids. Nevertheless, .it is desirable that printing assistants be incorpov rated in the powders-at the time of manufacture A for the same reasons which apply in the caseof dye pastes. e I V Dye pastes containing various liquid printing assistants have been made. Among theliquid materials used are the alkylolamines', for example,"

triethanol amine; and] or polyhydric alcohols such as giycerine, glycol,diethylene glycol and the like.

Various derivatives therefrom also have been tried. Iiil a printing aid is to be incorporated in a dye powder, a solid printing aid is necessary. Examples of such solids which have been used in the past include the hydrochlorides of alkylol amines; silver salt (sodium anthraquinone betasulphonate); anthraquinone and certain metal salts such as those of cobalt and iron.

Unfortunately, most of these printing aids previously used are not as satisfactory as may he desired. Many of them will not in all cases produce 7 the'intensiflcation of color for which they were intended. Others, such as the polyhydric alcohols, cause deterioration of .the printing-color pastes so that marked variations in the strength of prints therefrom are observable even after the printing-color paste has been allowed to stand for only a relatively short time. Many of them are satisfactory with somecolors but have an adverse eifect on others, even-to the extent of visibly altering the shade. None of them are suitable without. 1 modification for use both in paste and powder .compositions.

There remains, therefore, a demand for suitable printing "assistant which will produce. a satis-- factory eolor intensification and will not cause deterioration of the dyeing or printing composition on standing. Preferably the assistants should be useful both with dye and dye powders and in addition should be readily available orcheaply and easily prepared. It is, therefore, the object of the present invention to pro:

easier, but in addivide a new type of printing assistant which posisolated,

sesses these desirable Prop rties.

In general the objects of the present invention are accomplished by using as a printing assistant a quinonyl-suiphonamide having a terminal polar latter with diethanolamine.

group.. Such compounds may be represented by the general formula 1 ethylene diamine and the other alkyl'ene an amines, guanidine carbonate, biguanide, melaz mine and the like. a

'in which Q represents the residue of a quinone such as alpha or beta anthraquinone and betanaphthoquinone; R1 and R2 represent hydrogen with-ethanol amine. This compound gives an excellent printing assistant. Similarly, the N-diethanol sulphonamides of beta-'anthraquinone sulphonic acid may be prepared by reacting the Other useful prodnets are obtained for example by the condensation of. a 'quinone-sulphonyl chloride and urea,

While the dye and printing paste compositions of the present invention are not limited to the use of any particular dyes or dye forms; they are especially suitable for use with vat-dyes in either n alkanol, aminoethyl, c y a 00 15' paste or powder form. Particularly good results densed carbanryl radical and 'a: may be 1 or 2.- Typical of the sulphonamides containing additional polar groups suitable for use according to the present invention are the monoand which may be represented by the formulae:

So far as the present invention is concerned the assistants may be added to the printing-color pastes at any point. They may be incorporated may be obtained using the-vat-dyev powders of high autodispersibility set forth in Crossley et 8.1., United States Reissue Patent 21,402, reissued March 19', 1940. By combining the color matedi-N-ethanol,beta-anthraquinonylsulphonamides go rials or that atent into printingaste'compositions containing the printing assistants of the present "invention, the full. advantages of both may be gained with a resultant simplicity in use and excellence of shade and sharpness of color.

The invention will be more fully-set forth in connection with the following examples which are intended to be illustrative and not by way of limitation. All parts are by weight unless other- .wisenoted.

In the succeeding examp1es,-test prints were cotton print-cloth. Ageing of the prints was carried out in a steam ager which was constructed in such a manner that controlled temperatures could'be used. The temperature range normally used was 100-l05 C. Those ageings referred to the thickener; into the dye pastes or 40 as plant or hot ageings were carried out in the ders or may be blended directly into the printingcolor paste. However, as pointed out above, it is preferable that they be incorporated in the dye paste or powder during manufacture.

temperature range of about 106-110 C.- In the case of the cotton prints ageing periods of 3 minutes, 5 minutes or both were used. 0n rayon, ageing periods of 5 and 10 minutes or both were The use of this new class 0! printing assistants used. The shortest period which gives a satisfacpossesses a number of important advantages. These compounds are dry solids, which may be readily powdered and blended in dye powders but are also soluble or dispersible in dye paste suscation in both dye pastes and dye powders. They do not cause deterioration of printing-color pastes on standing. They encourage the production of excellent color yields even under hot ageing contory ag'eing is preferable.

Example 1 I Apaste was prepared by slurrying 2,000 parts p sio s- T y fiv ,.therefore, a general appliso of British gum (Stein Hall) in 5,000 parts of water and the mixture was heated with contin-' uous' stirring until the temperature reached about 185 1. Heating was continued for about 1% hours after which 450 parts of powdered sodium ditions. Their useis simple since they may be carbonate and 450 parts of powde ed Potassium employed as powders, as suspensions in water or are impractical to form.v

Compounds such as those used according to the present invention are readily prepared by-con- 7o dcnsing a quinone-suiphonic acid with orby reacting. a quinone-sulphonyl chloride with a suit able I'br example, the N-ethanol betaanthraquinone sulfonamide may be prepared by reacting beta-anthraquinone sulphonyl chloride tinued until the temperaturedecreased to beta-naphthoquinone.
