Description

Verfahren zur Erhöhung der Lichtechtheit von Farblacken Durch das Patent 539 174 ist ein `"erfahren zur Herstellung lichtechter Lacke unter Schutz gestellt. Es besteht darin, daß man die danach erhältlichen reduzierten komplexen Phosphorwolframmolybdänsäuren zur Herstellung von Lacken aus basischen oder sauren aminogruppenhaltigen Farbstoffen verwendet.Process for increasing the lightfastness of colored lacquers Patent 539 174 is experienced in the production of lightfast paints under protection posed. It consists in having the reduced complexes obtainable thereafter Phosphorus tungsten molybdic acids for the production of lacquers from basic or acidic dyes containing amino groups are used.

Es wurde gefunden, daß die Lichtechtheit dieser Lacke dadurch wesentlich erhöht wird, daß man nach dem Fällen der Farbstoffe mit der reduzierten -Komplexverbindung die Lacke kocht. Die Lacke werden in üblicher Weise hergestellt, und es ist dabei gleichgültig, ob man. die reduzierte komplexverbindung zunächst abscheidet und eine Lösung derselben als Fällungsmittel benutzt, oder ob man die reduzierte Lösung der normalen komplexen Phospliorwolframinolybdänsäure zum Fällen benutzt. Als Substrate eignen sich die verschiedenartigsten, z. B. Tonerdehydrate, Tonerdeblancfix, Krapplacksubstrat, Aluminiumphosphat oder Aluminiumsilicat.It has been found that this makes the lightfastness of these paints essential is increased that after precipitating the dyes with the reduced complex compound the paint boils. The varnishes are made in the usual way, and it is included no matter whether one. the reduced complex compound is initially deposited and a Solution of the same used as a precipitant, or whether one uses the reduced solution of the normal complex phosphotungsteno molybdic acid used for felling. As substrates the most diverse, z. B. Alumina hydrates, Alumina blancfix, madder lacquer substrate, Aluminum phosphate or aluminum silicate.

Beispiel i 15 Gewichtsteile schwefelsaure Tonerde, iSo;oig, i : io gelöst, werden zu 7,5 Gewichtsteilen Soda calc., i : io gelöst, gegeben. Nach dreimaligem Auswaschen durch Dekantieren werden 1,5 Gewichtsteile Methylviolett i B (s. Schultz, Farbstofftabellen 1923, Band i, Seite 167, Nr. 515), 3 Gewichtsteilen des nach dem Patent 539174 hergestellten Reduktionsproduktes aus Phosphorwolframmolybdänverbindungen, i : io gelöst, zugegeben und ungefähr 2 Stunden gekocht. Nach dem Abkühlen wird der sehr lichtechte Lack abfiltr fiert.Example i 15 parts by weight of sulfuric acid clay, iSo; oig, i: io dissolved, are added to 7.5 parts by weight of soda calc., i: io dissolved. After three times Washed out by decanting, 1.5 parts by weight of methyl violet i B (see Schultz, Dye tables 1923, Volume i, page 167, No. 515), 3 parts by weight of the after Patent 539174 produced reduction product from phosphotungsten molybdenum compounds, i: io dissolved, added and cooked for about 2 hours. After cooling it will the very lightfast paint is filtered off.

Beispiel 2 5,5 Gewichtsteile schwefelsaurer Tonerde, 18 ojoig, i : i o :gelöst, 3,6 Gewichtsteile Natriumphosphat, i:io gelöst, und 1,6 Gewichtsteile Soda cale., i : io gelöst, werden zusammengegeben. Nacn dreimaligem Auswaschen durch Dekantieren wird i Gewichtsteil Rhodamin B extra (s. Schultz, Farbstofftabellen 1923, Band i, Seite 192, Nr. 573), 2 Gewichtsteile des nach Patent 539 174 hergestellten Reduktionsproduktes aus Phosphorwolframmolybdänverbindungen, i_ : io gelöst, zugegeben und ungefähr 2 Stunden gekocht. Nach dem Abkühlen wird der sehr lichtechte Lack abfiltriert.Example 2 5.5 parts by weight of sulfuric alumina, 18 ojoig, i: i o: dissolved, 3.6 parts by weight of sodium phosphate, i: io dissolved, and 1.6 parts by weight Soda cale., I: io dissolved, are put together. After washing out three times One part by weight of Rhodamine B extra is decanting (see Schultz, color tables 1923, volume i, page 192, no. 573), 2 parts by weight of that prepared according to patent 539,174 Reduction product from phosphotungsten molybdenum compounds, i_: io dissolved, added and cooked for about 2 hours. After cooling, the lacquer is very lightfast filtered off.

Beispiel 3 5 Gewichtsteile schwefelsaure Tonerde, 18o;öig, i : io gelöst, 2,5 Gewichtsteile Soda calc., i : io gelöst, i Gewichtsteil Säuregrün GG extra (s. Schultz, Farbstofftabellen, Seite i 6o, Nr. 5o5), o,6 Gewichtsteile des nach dem Patent 539 174 hergestellten Reduktionsproduktes aus Phosphorwolframmolybdänverbindungen, i : io gelöst, und 7 Gewichtsteile Chlorbarium werden zusammengegeben und I Stunde gekocht. Nach dem Abkühlen wird abfiltriert.Example 3 5 parts by weight of sulfuric alumina, 18o; oil, i: io dissolved, 2.5 parts by weight of soda calc., i: io dissolved, i part by weight of acid green GG extra (see Schultz, Dye Tables, page i 6o, no. 5o5), 0.6 parts by weight of the reduction product prepared according to patent 539 174 from phosphotungsten molybdenum compounds, i: io dissolved, and 7 parts by weight Chlorbarium are given together and cooked for I hour. After cooling, it is filtered off.
