    Abstract: Aqs. printing paste for the transfer printing of cellulose contg. material, e.g. cotton, rayon, contains, calc. on the printing paste, (a) 1-30%, pref. 5-15%, of reactive or vat dyes, (b) 1-50%, pref. 10-30%, of a water-sol. polyethylene oxide of pref. m. wt. 3000-6000 and having structure, and opt. (c) an emulsion thickener, pref. composed of heavy gasoline (b.pt. 140-200 degrees C), water, on emulsifier of the oil-in-water type and opt. a thickener swelling in water. Sharp outlines are obtd. with no sublimation of the dyestuff, and a wide range of dyes may be used. The pastes contain little or no solvent and may be applied conventionally onto the dyestuff carrier strips in the usual way.

    Abstract: In the printing or discharge printing of textile materials a paste is employed containing a vat dyestuff or a disperse dyestuff resistant to reducing agents or a mixture thereof, an amine, a reducing agent comprising a water-insoluble or sparingly soluble salt of a hydroxyalkyl sulphinic acid, a thickening agent and a swelling agent. Specified amines are ethylene diamine, dodecylamine, diethanolamine, di-isopropanolamine, n-butyl-ethanolamine, triethanolamine, tripropylamine, cyclohexylamine, hexahydro-o-toluidine, N-methylcyclohexylamine, dimethylaniline and dimethyl-p-phenylene diamine. Specified reducing agents are the calcium, barium or secondary zinc salts of hydroxymethane-, hydroxyethane- and hydroxybutane-sulphinic acids. Specified thickeners are crystal gum and tragacanth. Specified swelling agents are phenol, resorcinol, ammonium oxalate, polyethylene glycol and the sodium salt of benzylsulphanilic acid. Examples describe the direct printing of fabrics of cotton, regenerated cellulose fibres and polyethylene terephthalate fibres, and the colour discharge printing of fabrics of cellulose acetate, cellulose triacetate, polycaprolactam and wool fibres. Specifications 702,040, 702,041 and 711,154 are referred to.
