Abstract: 548,172. Emulsions. GROVES, W. W. (Durand and Huguenin Akt.-Ges.) March 11, 1940, No. 4518. [Class 1 (i)] [Also in Group IV] A printing paste or padding solution containing a white pigment, or a substance capable of yielding a white pigment by double decomposition, and blood or egg albumen in an amount of at least 1 per cent. of the paste or solution, in admixture with an aqueous dispersion or emulsion of a non-coagulable substantially waterinsoluble substance is used for the production of matt effects on lustrous fibrous material (see Group IV). A dispersing or emulsifying agent and, if necessary, a stabilizer, may be present in the paste or solution. Specified white pigments are titanium dioxide, zinc oxide, zinc sulphide, barium sulphate and water-insoluble ureaformaldehyde condensation products. Specified non-coagulable water insoluble substances are toluene, xylene, petroleum, paraffin oils, halogenated hydrocarbons, e.g. tetrachlorethane or trichlorethylene, high-boiling alcohols, e.g. octyl alcohol, olive oil, castor oil, vaseline and waxes. In examples (1) and (2) a lustrous viscose fabric is treated with an aqueous Marseilles soap emulsion of petroleum and castor oil containing titanium dioxide and egg albumen; (3) similar fabric is printed with an aqueous triethanolmine stearate dispersion of hard paraffin containing titanium dioxide and egg albumen; (4) egg albumen is intimately mixed with an aqueous triethanolamine dispersion of hard paraffin and the mixture is dried under reduced pressure at 40‹C. and powdered for convenience in marketing; lustrous viscose artificial silk yarn is padded with an aqueous paste of this powder with an addition of titanium dioxde; (5) a lustrous viscose artificial silk fabric is padded with an aqueous Marseilles soap emulsion of xylene containing titanium dioxide and egg albumen; (6) a similar fabric is printed with an emulsion as in (1) containing also carragheen moss thickening; (7) a similar fabric is printed with an aqueous triethanolamine oleate emulsion of mineral oil and hard paraffin containing titanium dioxide and egg albumen; (8) a lustrous viscose or natural silk fabric is printed with an aqueous Marseilles soap emulsion and castor oil containing zinc oxide and egg albumen; (9) a lustrous viscose artificial silk fabric is printed with an aqueous Marseilles soap emulsion of petroleum and castor oil containing a water-insoluble ureaformaldehyde condensate, and egg albumen; (10) a similar fabric is printed with an aqueous Marseilles soap emulsion of petroleum and castor oil containing titanium dioxide and egg albumen; (13) a similar fabric is padded with an aqueous Marseilles soap emulsion of petroleum and castor oil containing barium chloride and egg albumen, and the padded fabric is dried and treated with dilute sulphuric acid to produce barium sulphate and to coagulate the albumen; (14) a similar fabric is padded with an aqueous Marseilles soap emulsion of petroleum and castor oil containing titanium dioxide, egg albumen, the sodium salt of the sulphuric acid ester of leuco-6-ethoxy - 4<SP>1</SP> - methyl - 6' - chlorothioindigo, ammonium thiocyanate, sodium chloride and ammonium vanadate; (15) a similar fabric is padded with an aqueous Marseilles soap emulsion of petroleum and castor oil containing titanium dioxide, egg albumen and Chlorantin light blue GLN; (16) a similar fabric is padded with an aqueous Marseilles soap emulsion of petroleum and castor oil containing titanium dioxide, egg albumen, the azo dyestuff, 2:5- dichloroaniline#the 2<SP>1</SP>-anisidide of 2:3-hydroxynaphthoic acid, esterfied with benzoic acid-msulphochloride, thiodiglycol and urea; (17) a similar fabric is padded with an aqueous Marseilles soap emulsion of petroleum and castor oil containing titanium dioxide, egg albumen, Chromocitronin R and chromium acetate; (18) a similar fabric is padded with an aqueous Marseilles soap emulsion of petroleum and castor oil containing egg albumen, the sodium salt of the sulphuric acid ester used in (14), barium chloride and sodium nitrate and the padded fabric is dried and treated with dilute sulphuric acid; (19) and (20), a similar fabric is printed with an aqueous resist paste containing (19) glue and starchtragacanth thickening, (20) gum arabic, and the print is dried, padded with an aqueous Marseilles soap emulsion of petroleum and castor oil containing titanium dioxide and egg albumen; (21), (22) and (23) a similar fabric is printed with an aqueous paste containing gum arabic, chromium acetate, sodium formate, urea and (21) Chromocitronin R, (22) 1:3-diaminobenzine # salicylic acid (1 mol.) and N-acetyl- 1:8 aminonaphthol-4:6-disulphonic acid (1 mol.) (cf. Specification 2:31,885. [Class 2 (iii)]), (23) the sulphonated anilide of the gallocyanine dyestuff from nitrosodiethyl-m-toluidine and gallamide (cf. Specification 301,329, [Class 2 (iii)]), and the print is dried, steamed, and padded as in (19) and (20); (24) and (25) a similar fabric is printed with an aqueous paste containing gum arabic, sodium thiosulphate, chromium acetate, sodium formate, urea, oxalic acid and (24) Chromocitronin R (25) the dyestuff of (22) above, and the print is steamed, padded with an aqueous Marseilles soap emulsion of petroleum and castor oil containing the sodium salt of the sulphuric acid ester of leuco- 4-methyl-5-chloro-7-methoxy-4<SP>1</SP>-chloro-2-indol-2<SP>1</SP>- naphthalene-indigo, titanium dioxide, egg albumen, ammonium thiocyanate, sodium chlorate and ammonium vanadate.
