ABSTRACT:
After being deposited on the luminescent screen, the dispersion lacquer made by the method disclosed forms a smooth and uniform film whose fluidity can be influenced. This results in an improved reflectance behavior of the deposited aluminum film and, thus, in greater picture brightness.
The disclosed method consists in that a boric-acid solution is added to the dispersion lacquer which is then set to the desired viscosity by means of a neutralizer.
