Description
Von Papier leicht entfernbare Druckfarben. Es ist bekannt, daß es nur sehr schwierig und niemals vollständig gelingt, die Druckerschwärze, die aus Kienruß und irgendeinem (5lfirnis besteht, von Papier zu entfernen. Man hat daher schon empfohlen (vgl. Patentschrift 24.08), Braunstein oder Oxyde des Mangans an Stelle von Kienruß zu verwenden und diese von dem bedruckten Papier durch Behandeln mit unterschwefligsauremNatron oder Salzsäure zu entfernen. Dieses Zerfahren hat aber nie wirtschaftliche Bedeutung erlangt.Printing inks that can be easily removed from paper. It is known that it only very difficult and never completely succeeds in getting the ink that comes out Soot and any kind of varnish has to be removed from paper already recommended (see patent specification 08/24), brownstone or oxides of manganese Instead of using pine soot and treating this from the printed paper remove with hyposulphurous sodium or hydrochloric acid. This has disintegrated but never achieved economic importance.
Es wurde nun gefunden, daß man eine recht gut und bequem von Papier entfernbare Braunsteinfarbe herstellen kann, wenn man an Stelle der sehr teuren Leinölfir nisse oder der aus Cumaronharzen und Mineralölen hergegestellten Firnisse gechlorte Kohlenwasserstoffe der aliphatischen oder aromatischen Reihe oder Stoffe verwendet, die aus Halogenadditionsprodukten des Naphthalins oder seiner Abkömmlinge- durch Halogenwasserstoffabspaltung gewonnen wird.It has now been found that one can get a fairly good and comfortable one from paper Removable brownstone paint can be made if you can replace the very expensive ones Linseed oil varnishes or varnishes made from coumarone resins and mineral oils chlorinated hydrocarbons of the aliphatic or aromatic series or substances used, which from halogen addition products of naphthalene or its derivatives is obtained by elimination of hydrogen halide.
Die gebräuchlichen Leinölfirnisse sind für den Zweck der Erfindung, abgesehen von dem hohen Preis, wenig geeignet, weil sie nach Entfernung der Druckfarbe fettig durchscheinende Stellen im Papier hinterlassen, so daß dessen Verwendung hierdurch erschwert, wenn nicht wirtschaftlich unmöglich gemacht wird. Druckfarben, die mit den vorbezeichneten Stoffen hergestellt sind, hinterlassen dagegen nach Entfernung des Pigments keine durchscheinenden Stellen. Beispiele 1. 75 Gewichtsteile gechlortes Paraffin ,spez. Gew. etwa i,135 bei 1g°, enthaltend etwa 40 Prozent Chlor) werden mit 25 Gewichtsteilen natürlichen Braunsteins zu einer Farbe fein verrieben. Durch Behandeln des mit dieser Farbe bedruckten Papiers mit zweiprozentiger wäßriger schwefliger Säure oder Ameisensäure läßt sich die Druckerschwärze leicht entfernen.The common linseed oil varnishes are for the purpose of the invention, apart from the high price, not very suitable because they are after removal of the printing ink leave greasy, translucent spots in the paper, so that it can be used this makes it difficult, if not made economically impossible. Printing inks, which are made with the aforementioned substances, however, leave behind Removal of the pigment no translucent areas. Examples 1. 75 parts by weight chlorinated paraffin, spec. Weight about 1. 135 at 1g °, containing about 40 percent chlorine) are finely rubbed into a color with 25 parts by weight of natural brown stone. By treating the paper printed with this color with two percent aqueous The printing ink can be easily removed with sulphurous acid or formic acid.
75 Gewichtsteile einer aus Halogenadditionsprodukten des Naphthalins oder seiner Abkömmlinge durch Halogenw asserstoffabspaltung gewonnenen Masse von firnisartiger Konsistenz werden mit 25 Gewichtsteilen künstlichen goprozentigen Braunsteins zu einer schwarzen Farbe gut verrieben.75 parts by weight of one from halogen addition products of naphthalene or its derivatives obtained by splitting off hydrogen halide mass of varnish-like consistency with 25 parts by weight of artificial gop% Brown stones well rubbed to a black color.
