Abstract

Stronger prints and more rapid fixation are obtained in printing with thioindigoid dyestuffs by incorporating, in printing pastes containing the dyestuff, a thickening agent, hydrosulphite as reducing agent, an alkali and any other usual additions, a salt, oxide or hydroxide of a metal other than an alkali metal or an alkaline-earth metal, in a quantity amounting to from \ba1/20\be to \ba1/2\be a molecular proportion for each molecular proportion of pure dry dyestuff. The metal oxide, hydroxide or salt may be mixed with the dyestuff paste before making up the latter into the printing paste. In examples, (1) 4 : 4<1>-dimethyl-6 : 6<1>-dichlorthioindigo is pasted with glycerine, wheat starch - tragacanth thickening, sodium benzylsulphanilate, sodium carbonate, and hydrosulphite, the paste is heated to reduce the dyestuff, mixed with ferric chloride and sodium formaldehyde-sulphoxylate, printed on the material and the latter is steamed, washed and finished, and (2) 6 : 6<1>-diethoxythioindigo and 6-methoxy-4 : 6<1>-methyl-chlorthioindigo (made by condensing 6-methoxy-3-oxythionaphene with 4-methyl-6-chlor-2 : 3-dihydro-3-ketothionaphene-2-dimethylamino-anil) are printed in a similar manner, with addition of copper sulphate and zinc sulphate respectively in place of ferric chloride.
