Description

Leuchtende Schreibplatte Eine aus Celluloid, Acetylcellulose o. dgl. bestehende Platte, d. h. eine Platte aus durchsichtigem oder durchscheinendem Material wird auf der einen Seite mit Leuchtfarbe, welcher ein geeignetes Bindemittel beigefügt ist, bestrichen. Die bei Dunkelheit durchscheinende Leuchtfarbe gestattet ohne jede Hilfe einer äußeren Beleuchtung, sichtbar zu schreiben oder zu zeichnen und das Geschriebene zu lesen.Luminous writing board One made of celluloid, acetyl cellulose or the like. existing plate, d. H. a sheet of transparent or translucent material is on one side with luminous paint, to which a suitable binding agent is added is coated.

Zur Erleichterung des Schreibens kann die Schriftseite der Platte angerauht werden.To make writing easier, the writing side of the plate be roughened.

Die Leuchtfarbenschicht wird, wie für andere Zwecke allgemein üblich, mit einer Schutzschicht aus einem härtenden oder schützenden Material überzogen oder mit einer Platte aus Papier, Pappdeckel üsw. oder einer reflektierenden Fläche hinterlegt. Diese Schonschicht erhöht gleichzeitig die Wirkung der Leuchtfarbe, welche nun nur noch nach einer Seite ausstrahlen kann.The luminous paint layer is, as is common for other purposes, covered with a protective layer of a hardening or protective material or with a sheet of paper, cardboard cover, etc. or a reflective surface deposited. This protective layer also increases the effect of the luminous paint, which can now only radiate to one side.

Die Leuchtfarbe kann aber auch in bekannter Weise dem Material, z. B. Celluloid, Acetylcellnlose, Papier usw. gleich beigemischt werden oder zwischen zwei Lagen eingebettet sein, so daß die Platte auf beiden Seiten beschrieben werden kann.However, the luminous color can also be added to the material in a known manner, e.g. B. Celluloid, Acetylcellnlose, paper, etc. are mixed in or between two layers must be embedded, so that the plate can be written on on both sides can.
