Description
<Desc/Clms Page number 1>
Verwendung von schwer- oder unlöslichen Fettseifen als Zusatz zur Leimung von Papieren für photographische Zwecke.
EMI1.1
<Desc/Clms Page number 2>
Will man diese Leimung auf Fertigprodukten anbringen, sei es auf geleimten oder ungeleimten, oder beabsichtigt man, eine solche Leimung der Barytage beizufügen, so wird z. B. einer ziemlich konzentrierten Gelatinelösung die Fettseife mit dem entsprechenden Chlorsalz zugeteilt und mittels Alaun diese Fettseife in schwer-bzw. unlösliche Form übergeführt. Bei Beimischung von phosphorsauren Salzen zur Fettseife wird jedoch an Stelle von Kalialaun Kalziumsalz oder gleichzeitig Kaliumsalz und Kalialaun beigefügt, wo- durah das phosphorsaure Salz und die Fettseife unlöslich worden.
Man kann aber auch einer ziemlich konzentrierten Gelatinelösung direkt Kali-Ton- erdealaun beifUgen, dann ohne jeden Chlorzusatz die Fettseife zur Gelatinelösung gel) en und schliesslich die Fettseife mit Kaliumsalz unlöslich machen.
Bei den vorgenannten Verfahren können bei Bedarf die in der fertigen Gelatinefettseifenmischung befindlichen löslichen Produkte nach Erstarren der Mischung durch kurzes Waschen entfernt werden.
Behandelt man Rohpapier mit derartiger Präparation, so ist es möglich, ohne weitere Barytage oder nur mit sehr dünner Barytage dieses Papier zu emulsionieren, ohne dass die eventuell im Papier enthaltenen Metallteilchen mit der auf das Papier zu bringenden Emulsion in Reaktion treten.
Es ist bereits bekannt, zur Förderung des gleichmässigen Fliessens auf Glas oder Papier gewissen Emulsionen geringe Mengen löslicher Seifen zuzusetzen. Demgegenüber handelt es sich aber bei dem vorstehenden Verfahren um die Benutzung unlöslicher oder schwerlöslicher Fettseifen, durch die, wie dargelegt, eine wesentlich andere Wirkung bezweckt und erreicht wird.

Use of poorly soluble or insoluble fatty soaps as an additive for sizing papers for photographic purposes.
EMI1.1
<Desc / Clms Page number 2>
If you want to apply this glue to finished products, be it on glued or unsized, or if you intend to add such glue to the bar days, z. B. a fairly concentrated gelatin solution assigned the fatty soap with the appropriate chlorine salt and using alum this fatty soap in heavy or. insoluble form. If phosphoric acid salts are added to the fatty soap, however, instead of potassium alum, calcium salt or at the same time potassium salt and potassium alum are added, whereby the phosphoric acid salt and the fatty soap become insoluble.
However, one can also add potash clay alum directly to a fairly concentrated gelatin solution, then gel the fatty soap to the gelatin solution without any addition of chlorine and finally make the fatty soap insoluble with potassium salt.
In the above-mentioned processes, the soluble products in the finished gelatin fat soap mixture can be removed by brief washing after the mixture has solidified.
If raw paper is treated with such a preparation, it is possible to emulsify this paper without further baryages or only with very thin baryages, without the metal particles possibly contained in the paper reacting with the emulsion to be applied to the paper.
It is already known to add small amounts of soluble soaps to certain emulsions to promote even flow on glass or paper. On the other hand, the above method involves the use of insoluble or sparingly soluble fatty soaps, which, as explained, aim and achieve a significantly different effect.
