Description

Verfahren zur Herstellung lichtechter Lacke Es wurde gefunden, zu lichtechten Lacken dadurch zu gelangen, daß man saure Farbstoffe, welche außer einer oder mehreren Sulfogruppen eine oder mehrere freie oder substituierte Aminogruppen enthalten, bei Gegenwart von komplexen Wolframsäuren mit basischen Farbstoffen übersetzt. Die Lichtechtheit einer derartigen Fällung ist ebenso groß wie die einer Mischung aus dem mit Phosphorwolframmolybdänsäure gefällten sauren Farbstoff und aus dem mit Phosphorwolframmolybdänsäure gefällten basischen Farbstoff. Das Verfahren bedeutet also gegenüber den bisher bekannten Verfahren, solche lichtechten Lacke herzustellen, eine wesentliche Ersparnis an PhoAphorwolframmolybdänsäure.Process for the production of lightfast paints It has been found to To get lightfast paints by using acidic dyes, which except one or more sulfo groups one or more free or substituted amino groups contain, translated with basic dyes in the presence of complex tungstic acids. The lightfastness of such a precipitation is just as great as that of a mixture from the acidic dye precipitated with phosphotungstic molybdic acid and from the basic dye precipitated with phosphotungstic molybdic acid. The procedure means So compared to the previously known processes to produce such lightfast paints, a substantial saving of pho-phorotungframolybdic acid.

(i: =o in Wasser gelöst) versetzt und =i Gewichtsteile Chlorbarium krist. (z : =o in Wasser gelöst) hinzugefügt. Hierzu gibt man die heiße wäßrige Lösung von 2 Gewichtsteilen des Farbstoffes aus Diäthyl-p-aminobenzaldehyd und 2 Mol. Äthylbenzyl-m-toluidinmonosulfosäure, o,96Gewichtsteile Phosphorwolframmolybdänverbindung (i: =o in Wasser gelöst) (s. Patentschrift 445 151) und übersetzt mit z Gewichtsteil des Gemisches des Farbstoffes aus Tetra-, Penta- und Hexamethylenrosanilin. Beispiel 2 5o Gewichtsteile Schwerspat werden mit =o Gewichtsteilen schwefelsaurer Tonerde 18 A1203 (i: =o in Wasser gelöst) aufgeschlämmt, mit 4 Gewichtsteilen Soda calc. (i: =o in Wasser gelöst) versetzt und hierzu =i Gewichtsteile Chlorbarium krist, (i: =o in Wasser gelöst) hinzugefügt. Hierzu gibt man die heiße wäßrige Lösung von 2 Gewichtsteilen des Farbstoffs aus dem Dinatriumsalz von der Diäthyldibenzyldiamidotriphenylcarbinoltrisulfosäure sowie 1,2 Gewichtsteile Phosphorwolfram.molybdänverbindung (i: io in Wasser gelöst) (s. Patentschrift q.45151) und. i Gewichtsteil des Farbstoffs aus dem Natriumsalz der Methyldehydrothiotoluidinsulfosäure.Example i 50 parts by weight of barite become with = o parts by weight Sulfuric alumina 18% A1203 (i: io dissolved in water) slurried with 5 parts by weight soda calc. (i: = o dissolved in water) added and = i parts by weight Chlorbarium crystall. (z: = o dissolved in water) added. For this you give the hot one aqueous solution of 2 parts by weight of the dye from diethyl-p-aminobenzaldehyde and 2 moles of ethylbenzyl-m-toluidine monosulfonic acid, 0.96 parts by weight of phosphotungsten molybdenum compound (i: = o dissolved in water) (see patent specification 445 151) and translated as z part by weight the mixture of the dye of tetra-, penta- and hexamethylene rosaniline. example 2 50 parts by weight of heavy spar are mixed with = 0 parts by weight of sulfuric alumina 18 A1203 (i: = o dissolved in water) slurried, with 4 parts by weight of soda calc. (i: = o dissolved in water) added and to this = i parts by weight of chlorobarium crystall, (i: = o dissolved in water) added. To this end, the hot aqueous solution of 2 parts by weight of the dye from the disodium salt of diethyldibenzyldiamidotriphenylcarbinol trisulfonic acid as well as 1.2 parts by weight of phosphotungsten molybdenum compound (i: io dissolved in water) (see patent specification q.45151) and. 1 part by weight of the dye from the sodium salt of methyldehydrothiotoluidine sulfonic acid.

Man erhält so lichtechte Fällungen einer Kombination von sauren und basischen Farbstoffen auf den in der Praxis üblichen Substratmischungen, die besonders für Tapetenfarblacke geeignet sind und trotz des erheblich geringeren Gehaltes an Phosphorwolframsäure dieselbe Lichtechtheit aufweisen wie die bisherbekannten analogen Lacke aus den in der-Einführung erwähnten Mischungen.This gives lightfast precipitations of a combination of acidic and basic dyes on the substrate mixtures customary in practice, the particularly are suitable for color varnishes for wallpaper and despite the considerably lower content of Phosphotungstic acid have the same lightfastness as the previously known analogs Paints from the mixtures mentioned in the introduction.
