Description

Verfahren zur Herstellung von Anilindruckfarben aus Pigmenten und/oder lasierenden Farbstoffen Zur Herstellung von Anilindruckfarben werden bis jetzt in der Regel die löslichen, verhältnismäßig teuren Anilinfarbstoffe verwendet. Nur in seltenen Fällen hat man Pigmente o. dgl. auf Reibwalzen in Firnis verrieben und daraus Druckfarben hergestellt.Process for the production of anil printing inks from pigments and / or translucent dyes For the production of aniline printing inks, in usually the soluble, relatively expensive aniline dyes are used. Just in rare cases pigments or the like have been rubbed into varnish on distribution rollers and printing inks made from it.

Es wurde nun gefunden, daß es durch Anwendung der bekannten Ultraschallwellen zum Dispergieren von Pigmenten und/oder lasierenden Farbstoffen in Anilindruckfarben gelingt, in verhältnismäßig kurzer Zeit sehr gleichmäßige, gut trocknende Druckfarben herzustellen. Daher können die teuren löslichen Anilinfarbstoffe weitgehend durch Pigmente oder lasierende Farbstoffe ersetzt werden.It has now been found that by applying the known ultrasonic waves for dispersing pigments and / or translucent dyes in aniline printing inks succeeds in producing very uniform, well-drying printing inks in a relatively short time to manufacture. Therefore, the expensive soluble aniline dyes can largely get through Pigments or translucent dyes are replaced.

Beispiel i io Teile Permanentrot F 4 R extra werden in go Teile einer Schellacklösung, bestehend aus 25 Teilen Schellack und 75 Teilen Spiritus, eingerührt. Dieses zunächst grobe Gemisch wird der Beschallung ausgesetzt, wonach eine hochdisperse Suspension entsteht, die zum Verdrucken auf Gummiwalzendruckmaschinen hervorragend geeignet ist.Example i io parts permanent red F 4 R extra are in go parts of a Shellac solution, consisting of 25 parts of shellac and 75 parts of alcohol, stirred in. This initially coarse mixture is exposed to the sonication, after which a highly dispersed one The result is a suspension that is excellent for printing on rubber roller printing machines suitable is.

Beispiel 2 12 Teile Hansagelb G transparent werden mit 78 Teilen einer Polyvinylacetatlösung, bestehend aus 24 Teilen Polyvinylacetat und 76 Teilen Spiritus, vermischt. Das Gemisch wird der Beschallung ausgesetzt. Es entsteht eine hochdisperse Suspension, die beim Verdrucken auf der Gummiwalzendruckmaschine die Druckformen nicht zusetzt und lasierende Druckschichten ergibt. Beispiel 3 2o Teile Miloriblau werden mit 8o Teilen einer Kunstschellacklösung, bestehend aus 3o Teilen Kunstschellack und 7o Teilen Spiritus, verrührt. Diese Farbmasse wird in einer Ultraschallflüssigkeitspfeife der Beschallung ausgesetzt. Es fällt hiernach eine Suspension an, in der infolge feinster Verteilung das Pigment nicht absetzt. Dadurch ist eine überraschend gute' Verdruckbarkeit auf Gummiwalzendruckmaschinen gewährleistet. Zur Erzeugung von Ultraschallwellen können beispielsweise die bekannten Ultraschallflüssigkeitspfeifen Verwendung finden.Example 2 12 parts of Hansa Yellow G become transparent with 78 parts of a Polyvinyl acetate solution, consisting of 24 parts of polyvinyl acetate and 76 parts of alcohol, mixed. The mixture is exposed to the sonication. The result is a highly dispersed one Suspension that forms the printing plates when printing on the rubber roller printing machine does not clog and results in translucent print layers. Example 3 2o Parts of Milori blue are mixed with 80 parts of an artificial shellac solution consisting of 3o parts artificial shellac and 7o parts alcohol, mixed together. This mass of paint will exposed to sonication in an ultrasonic liquid whistle. It falls below a suspension in which the pigment does not settle due to the finest distribution. This results in a surprisingly good printability on rubber roller printing machines guaranteed. For the generation of ultrasonic waves, for example, the known Find ultrasonic liquid whistles use.
