Description

Zierstellung von Spritzlacken Von Lacken auf Basis von Cellulosederivaten, wie sie z. B. als- Spritzlacke für Leder, Bleche oder andere Materialien in der Schuh-und Automobillackindustrie Verwendung finden, wird verlangt, daß der färbende Anstrich keine Bestandteile enthält, die infolge ihrer Löslichkeit durch den Nitrocelluloselack hindurchwandern, den Glanz des Anstrichs so ungünstig beeinflussen oder gar auf der Oberfläche ausblühen (sogennante Sublimierechtheit).Decoration of spray paints of paints based on cellulose derivatives, how they z. B. as- spray paints for leather, sheet metal or other materials in the Shoe and automotive lacquer industries are used, it is required that the coloring The paint does not contain any components due to their solubility by the nitrocellulose paint wander through, affect the gloss of the coating so unfavorably or even on bloom on the surface (so-called sublimation fastness).

Es wurd nun gefunden, daß sich die Erdalkalisalze von sulfogruppenhalügen Farbstoffen aus dianotierten Nitroaminen und Acetessigaivliden mit beliebiger Stellung der Sulfogruppen als färbende Bestandteile für derartige Lacke hervorragend eignen. Mit Hilfe solcher Pigmente hergestellte Lacke sind sublinaierecht, farbstark und hervorragend lichtecht.It has now been found that the alkaline earth salts contain sulfo groups Dyestuffs from dianotized nitroamines and acetessigaivlides in any position the sulfo groups are ideally suited as coloring constituents for such paints. Varnishes produced with the help of such pigments are fast to subline, strong in color and excellent lightfast.

Beispiel Man vergastet 5 Gewichtsteile des Calciumsalzes des aus diazoüerter 5-Nitro-2-aminobenzoesäure und Acetessig-2-anisididsulfosäure erhältlichen Farbstoffs mit i o Gewichtsteilen Phthalsäurediäthylester. Diese Masse verrührt man mit einer Lösung von 12o Gewichtsteilen käuflicher Collodiumwolle (entsprechend 6o Gewichtsteilen trockner Collodiumwolle) in 25o Gewichtsteilen Äthylenglykolmonoäthyläther, Zoo Gewichtsteilen Aceton, q.5o Gewichtsteilen Äthylalkohol und i oo Gewichtsteilen Butylalkohol. Auf Blech aufgespritzt erhält man einen sublimierechten, sehr lichtechten Anstrich.EXAMPLE 5 parts by weight of the calcium salt of the diazoüerter are gasified 5-nitro-2-aminobenzoic acid and acetoacetic-2-anisididesulfonic acid available dye with 10 parts by weight of diethyl phthalate. This mass is mixed with a Solution of 120 parts by weight of commercially available collodion wool (corresponding to 60 parts by weight dry collodion wool) in 25o parts by weight of ethylene glycol monoethyl ether, zoo Parts by weight of acetone, q.50 parts by weight of ethyl alcohol and 100 parts by weight Butyl alcohol. Sprayed onto sheet metal you get a sublimation-proof, very lightfast Painting.

An Stelle des genannten Farbstoffs kann man mit gleichem Erfolg die Barium- oder Calciumsalze von Azofarbstoffen aus o-Nitranilinen, die auch substitutiert seinkönnen, einerseits und sulfierten Acetessigaryliden anderseits. verwenden. Ebenso sind geeignet die Erdalkalisalze der Farbstoffe aus sulfierten Nitranilinen und beliebigen Acetessigaryliden. Auch Azofarbstoffe aus 5-Nitro-2-aminobenzylw-sulfosäure und Acetessigaryliden sind zu obigem Verwendungszwecke gleichermaßen brauchbar.Instead of the dye mentioned, one can use the Barium or calcium salts of azo dyes made from o-nitroanilines, which are also substituted on the one hand and sulfated acetoacetic arylides on the other hand. use. as well are suitable the alkaline earth salts of the dyes from sulfated nitroanilines and any acetoacetic arylides. Also azo dyes made from 5-nitro-2-aminobenzylw-sulfonic acid and acetoacetic arylides are equally useful for the above purposes.
