Description

Verfahren zur Herstellung von durchsichtigen farbigen Überzügen auf Lampenumhüllungen. Bei der Herstellung von Überzügen auf Glas- u. dgl. Flächen, welche auf diese Weise zu Tageslichtfiltern gemacht werden, hat sich der Mißstand ergeben, daß beim Erhärten der Lösung, z. B. in Gelatine, manchmal von den gelösten Farbstoffen etwas wieder ausscheidet und alsdann auf der Fläche Pünktchen, Wolken u. dgl. bildet, die den Lichteindruck stören. Außerdem wird durch solche Inhomogenitäten das Mischungsverhältnis der Farbstoffe gestört und damit die gewünschte Färbung des erzeugten Tageslichtes verhindert.Process for the production of transparent colored coatings Lamp envelopes. When producing coatings on glass and similar surfaces, which are made into daylight filters in this way, the grievance has become show that when the solution hardens, e.g. B. in gelatin, sometimes of the dissolved Dyes are somewhat precipitated again and then there are dots and clouds on the surface and the like, which disturb the light impression. In addition, such inhomogeneities the mixing ratio of the dyes is disturbed and thus the desired color of the generated daylight prevented.

Es wurde nun gefunden, daß ein vollständig klarer Überzug unter allen Umständen gelingt, wenn in folgender Weise verfahren @` ird. Zunächst wird die Lösung, z. B. in Gelatine, hergestellt und dann die Erhärtung abgewartet. Es werden dann zur Herstellung des eigentlichen Überzuges solche Stücke der erhärteten Lösung verwandt, die vollständig klar sind. Diese werden wieder verflüssigt und nun auf die Lampe aufgetragen, auf der sie nach nochmaligem Erhärten den klaren, der gewünschten Tageslichtfarbe entsprechenden Filterüberzug bilden. Dieses Verfahren hat außer dem schon angegebenen noch den Vorteil, daß bei der Verwendung die nicht ganz einfache Herstellung der festen Lösung in den dafür geeigneten Fabriken erfolgen kann. Die Installateure usw., welche die Überzüge auf den Lampen vornehmen, brauchen sich dann mit der Zusammenstellung des Gemisches nicht mehr zu befassen, sondern nur die ihnen gelieferte feste Lösung zu verflüssigen.It has now been found that there is a completely clear coating among all Certain circumstances succeed if the following procedure @ `ird. First of all, the solution z. B. in gelatine, and then waited for hardening. It will then such pieces of the hardened solution are used to produce the actual coating, which are completely clear. These are liquefied again and now on the lamp applied on which, after further hardening, the clear, the desired daylight color Form a corresponding filter cover. This procedure has in addition to the one already indicated nor the advantage that when using the not very simple production of the solid solution can be made in the appropriate factories. The installers etc., which make the coatings on the lamps, then need to deal with the assembly of the mixture no longer to be concerned, but only the solid solution supplied to them to liquefy.
