as will be seenfrom the following examples, it offers to the dyers 'inany advantageous methods de'ues't ulf in storing, they can in this way 'be converted into products,
with the addition of morehydrosulfite'. The
I pastes containing the metallic-leuco-compounds are employed e thera'ssuch or after they have been concentrated oreven dried,
which is preferably done in vacuo. Glycerin, glue,
etc, may be added and the proportion of the components may be varied Within Wide limits.
The dyeingwith these leuco-compoundsis very simple. It consists inunixing the pastes with water with or without the addition of hydrosulfiteand then bringing the gookls to be dyed into contact with the suspended leuco-compounds for a longer or shorter time. p baths Generally speaking, with diluted the temperature oif thebathsis of influence:
Wool from WarmQand silk from lukewarm suspensions. These leuco-products may also be used for printingand as raw materials forthemanufacture of new dyestuffs. 85 parts ofa paste of magnesium-hydrate iandjlfi" l example 1: lfl'parts indigo,
parts of sodiumh ydrosulfite are ground to greenish paster' Example 2: 10; parts tetrabroinindigo 40%, 8 parts i 50%, 6 parts hydrosulfite, 2% parts Water i are, with the exclusion of air,kneaded together to a greenish tough paste. i
Example 3: 10 parts thioindigored, parts magnesiumhydrate-paste ,50%, parts glycerin, 12%, parts hydrosulfite and 5 kneaded together Example 4: :10 parts cibablue B B powder -(cibablue is tetrabroine-indigo), 100 parts magnesiumhydrate-paste 10%, 150
parts waterand parts hydrosulfite are heated together until "the formation of the insoluble yellow-greenish magnesium-leucocompound is completed. After cooling and filtering, the paste is ready fonshipment. Q
of using these dyestuffs. As"
besides hydrosulfitein the presence of comjpoundsof the metallic hydrates does not effect any Harmful overreduction' of the vat which are advantageously used for dyeing either direct or weaker dyeings are obtained, and, stronger ones with concentrated baths. Also 3 magnesiumhydrate-paste' with the exclusion of air to abrowntoughpaste;
7 Example parts l-ben zoylami noanthraquinone, 100 parts magnesiumhydrate paste 10% and 10 parts hydrosulfite' are gro'undatogether with the exclusion of air. The orangered leuco-compound is separated from'the solution by means of a press.
Example 6': 100 parts of a 10% paste of 1.5-dibenzoyldiaminoanthraquinone are vatted with 50 parts caustic soda 40 B., 100 partswater, and parts hydrosulfit'e.
, By theaddition of a cold solution of 80 parts crystallized magnesiumsulfate in 200 parts form byrfiltering and pressing.
Water, I the magnesium-leuco compound {is thrown ,down' as a olummous brown prec1p1tate, w-h1ch 1s brought 1nto a marketable Example 7 1O partshydronblue, 200parts magnesiumhydratepaste 5% and 10\p arts 'hydrosulfite are ground. together with the exclusion of air-to a yellow paste which is concentrated by filtering and pressing. .In
a slmlfiii manner, the magnesium-leuco-combrown color) are produced. The reaction is advantageously promoted by heating. Hy-
dronb'l'ue or ,cronblue is a product obtained by sulfurizing indophenol from p-nitrosophenol and carbazole; its exact chemical composition 1S unknown.

To give some examples the color of indigo is green- 3 1sh-yellow to yellow, of cibLabluelight greens of hydronviolet (with a copperish rown color) and of hydronyellow '(with a 7 ish-yellow, of thioindigo-scarlet 2 G bluishgray, of thioindigored 3 B greenish brown, of thioindigored B and of tetrabromindigo green, of 'cibaviolet brown, of benzoylaininoanthraquinone orange-red, of 1.5 dibenzoylaminoanthraquinone brown, of hydronblue yellow, of hydronviolet copperish-brown and of hydronyellow brown.
Ifexp'osed to air the products change their colorinto that of the vat-dyestuffs from v 1 which they are made. In case of mixtures the resulting color is a mixture'of the colors of the components.
With, 'ndigoid vat-dyestuffs in claims 1 and 2, I mean certain vat-dyestuffs similar to indigo, z. e. the derivatives of indigo (e; 'g. tetrabromindigo, ciba blue, ciba viof let) the thioincligc dyestuffs (e. g. thicindigo red, thio indigo 'violet), the vat-dyestuffs of the hydr'onseries (e. g. hydron blue, hydron violet, hydro n yellow), 1-ben-v zoylaminoanthraquinone, 1.5-dibenzoylaminoanthraquinone.
The; alkaline earth metals mentioned in the description and the claims can be substitutedby the earth metals, the light metals or the heavy metals but not by the alkaline I v metals.
1 claim: i l. The herein described new composition comprising a Ieuco-fcompound of a .derivative of ll'ldlgO' with alkaline earth metals which compound is almost insoluble in water and suited fordyeing and printing.
2. The herein'desc'ribed new mixture of a composition comprising a leuco-compou nd of a derivative of indigo with alkaline earth metals, and of hydrosulfitqwhich compound "is almost insolublein water suited for dyeing and printing,
In testimony whereofil have signed my name to this'speecification.
