Description

Verfahren zum Herstellen von Metallabformungen, insbesondere Druckformen von Kolloidreliefs Das Hauptpatent 613 325 betrifft ein Verfahren zur gleichzeitigen Herstellung von Metallabformungen und Kolloidreliefs, bei dem flüssiges Metall über einer belichteten Kolloidschicht ausgegossen wird, wodurch diese zu einem Relief aufgebläht wird und gleichzeitig eine Abformung in Metall gebildet wird.Method for producing metal impressions, in particular printing forms of colloidal reliefs The main patent 613 325 relates to a method for the simultaneous production of metal impressions and colloidal reliefs, in which liquid metal is poured over an exposed colloid layer, whereby it is inflated to a relief and at the same time an impression is formed in metal will.

Gegenstand der Erfindung ist eine weitere Ausbildung dieses Verfahrens, wobei plastischere Reliefs erzielt werden. Es bereitet gewisse Schwierigkeiten; die richtige Temperatur für das Aufgießen der flüssigen Legierung auf die Kolloidschicht zu treffen. Anscheinend ist dies darauf zurückzuführen, daß das Metall die Bildung einer zähen Oberflächenhaut oder einer Kruste verhindert oder zurückhält, die bei der Bildung des Reliefs an der Luft das Entweichen des sich entwickelnden Gases nicht zuläßt. Das Gas kann daher, wenn die Temperatur nicht genau bemessen ist, aus der Kolloidschicht nicht entweichen und einen guten Kontakt zwischen Metall und Matrize im Moment des Erstarrens verhindern. Dadurch ist es möglich, daß unter Umständen ein narbiger Metallabzug gebildet wird.The subject of the invention is a further development of this method, whereby more plastic reliefs are achieved. It causes certain difficulties; the right temperature for pouring the liquid alloy onto the colloid layer hold true. Apparently this is due to the fact that the metal is forming a tough surface skin or crust prevents or restrains the at the formation of the relief in the air, the escape of the developing gas does not allow. The gas can therefore, if the temperature is not measured precisely, from the colloid layer does not escape and good contact between metal and prevent die at the moment of solidification. This makes it possible that under A pitted metal print is formed under certain circumstances.

Diese Schwierigkeit wird gemäß der Erfindung dadurch überwunden, daß die Kollaidoberfläche mit einem plastischen Lack oder Firnis überzogen wird. Dies kann zu einem beliebigen Zeitpunkt vor der Entwicklung des Reliefs erfolgen. Man kann also den Lack unmittelbar vor oder nach der Belichtung aufbringen, falls die Emulsion nicht gleich bei der Herstellung des lichtempfindlichen Materials mit einem zweckentsprechenden Lack versehen wurde.This difficulty is overcome according to the invention in that the Kollaid surface is coated with a plastic lacquer or varnish. this can be done at any time prior to the development of the relief. Man can therefore apply the varnish immediately before or after exposure, if the Emulsion is not the same in the preparation of the photosensitive material with one Appropriate paint has been provided.

In der Abbildung ist ein Schnitt durch die Struktur eines Reliefpapiers gezeigt.The picture shows a section through the structure of a relief paper shown.

Auf der Unterlage, die normalerweise aus Papier besteht, ist eine Kolloidschicht gemäß dem Hauptpatent 613 325 aufgetragen. Ober dieser verhältnismäßig dicken Schicht befindet sich eine dünne Lackschicht. Von den Firnissen und Lacken haben sich die plastischen Celluloselacke, die z. B. aus Cellulosenitrat und einem Weichmachungsmittel bestehen, als besonders geeignet erwiesen.A colloid layer according to the main patent 613 325 is applied to the base, which normally consists of paper. On top of this relatively thick layer there is a thin layer of lacquer. From the varnishes and varnishes, the plastic cellulose varnishes, the z. B. consist of cellulose nitrate and a plasticizer, proven to be particularly suitable.

Die Reliefs und ihre Metallabgüsse fallen bedeutend plastischer aus, in Vergleich zu unlackierten, gleich behandelten Abzügen, wenn die Emulsion mit einer Lackschicht versehen ist.The reliefs and their metal casts are significantly more plastic, in comparison to unpainted, similarly treated prints when the emulsion with is provided with a layer of lacquer.

Die Zusammensetzung eines geeigneten Lackes ist etwa folgende: Cellulosenitrat ... 49, Tricresylphosphat . i g, Äthylacetat . . . . . 959 oder Cellulosenitrat . 5 g, Butylacetat . . . 3o g, Äthylacetat . . . 15- Äthylalkohol , . . 4.o g, Aceton . . . . . . i o g. Die aufgetragene Schicht muß möglichst dünn und gleichmäßig hergestellt sein. Zweckmäßig erfolgt dies auf einer geeigneten Gießmaschine sogleich nach Aufgießen der Emulsion.The composition of a suitable varnish is approximately as follows: Cellulose nitrate ... 49, Tricresyl phosphate. ig, Ethyl acetate. . . . . 959 or Cellulose nitrate. 5 g, Butyl acetate. . . 3o g, Ethyl acetate. . . 15- Ethyl alcohol, . . 4.og, Acetone. . . . . . io g. The applied layer must be made as thin and even as possible. This is expediently done on a suitable casting machine immediately after the emulsion has been poured on.

Das Verfahren ist nicht auf die besonders hervorgehobenen plastischen Celluloseesterlacke beschränkt. Vielmehr können auch eine Reihe von Harzlacken, Firnissen usw. Anwendung finden, wobei es ohne Bedeutung ist, ob man mit Gelatine oder anderen Kolloidemulsionen arbeitet.The procedure is not particularly emphasized on the plastic Cellulose ester coatings limited. Rather, a number of resin varnishes, Varnishes, etc. are used, regardless of whether you use gelatine or other colloidal emulsions.
