Description

Gummidruckfarbe Bekanntlich werden im Gunimidruck wäßrige alkoholische Lösungen von basischen Farbstoffen als Druckfarben verwendet, denen man als Verdickung Glycerin zusetzt. Meist erhalten diese Gummidruckfarben noch einen Zusatz von Tannin oder anderen zur Bildung von Farblacken geeigneten Stoffen, wodurch der Farbstoff auf der Unterlage mehr oder minder wasserfest fixiert wird.Gum printing inks It is well known that water-based alcoholic printing is used in gunimid printing Solutions of basic dyes are used as printing inks, which are called thickeners Adds glycerine. Most of these rubber printing inks also contain an addition of tannin or other substances suitable for the formation of color lakes, whereby the dye is fixed more or less waterproof on the base.

Es wurde nun gefunden, daß Gummidruckfarben, die wißrige alkoholische Lösungen vonFarbstoffen, daneben gegebenenfalls Tannin oder andere zur Farblackbildung geeignete Stoffe, sowie feste Polyalkylenoxyde enthalten, sich den unter Verwendung von Glycerin hergestellten Gummidruckfarben erheblich überlegen zeigen. Die zuzusetzende Menge an Polyalkylenoxyd, insbesondere Polyäthylenoxyd, kann in weiten Grenzen schwanken und richtet sich nach den jeweils vorliegenden Verhältnissen.It has now been found that rubber printing inks, the aqueous alcoholic Solutions of dyes, in addition, if necessary, tannin or other to form color varnish suitable substances as well as solid polyalkylene oxides are to be found using rubber inks produced by glycerine show considerably superior. The one to be added The amount of polyalkylene oxide, especially polyethylene oxide, can vary within wide limits and is based on the prevailing circumstances.

Beispiel .100 Gewichtsteile eines basischen Farbstoffes, z. B. D,iaxnantgrün GX (vgl. S c h u 1 t z , Farbstofftabellen IWI, Nr. 754), werden in iooo Gewichtsteilen Wasser unter Zusatz von 2oo Gewichtsteilen Äthylalkohol gelöst. Man fügt dann ,eine wäßrige Lösung von 3oo Gewichtsteilen Polyäthylenoxyd in 5oo Gewichtsteilen Wasser zu und erhält eine zum Bedrucken von Papierbahnen nach dem Gummidruckverfahren geeignete Druckfarbe.Example .100 parts by weight of a basic dye, e.g. B. D, iaxnant green GX (cf. S chu 1 tz , Dye Tables IWI, No. 754), are dissolved in 1,000 parts by weight of water with the addition of 2oo parts by weight of ethyl alcohol. An aqueous solution of 300 parts by weight of polyethylene oxide in 500 parts by weight of water is then added and a printing ink suitable for printing paper webs by the rubber printing process is obtained.
