Abstract
A method of manufacturing a luminescent screen assembly for a color cathode-ray tube (CRT) is disclosed. The luminescent screen assembly is formed on an interior surface of a faceplate panel of the CRT. The luminescent screen assembly includes color-emitting phosphors that are sequentially deposited over portions of the interior surface of the faceplate panel of the CRT. A filming composition is electrostatically sprayed over the color-emitting phosphors. The filming composition comprises an acrylic polymer dissolved in a solvent mixture of one or more high-volatility solvents combined with one or more low-volatility solvents.
