WATER SOLUBLE FLUORESCENT MATERIAL FOR COLOR IMAGE TUBES AND A PROCESS TO MANUFACTURE THE SAME.

摘要

The present invention provides a water soluble gallate fluorescent material with excellent luminous characteristics and a process to manufacture the color CRT using the same aforementioned material. Process improves luminous efficiency and color reproduction region and increases resolution due to electron point decrease from current reduction by electron beams in luminescence in the same fluorescent screen when introducing electro-photographic dry stencil process without using water.
