COATING SOLUTION FOR FPD PROTECTING FILM AND ITS PREPARATION

摘要

PROBLEM TO BE SOLVED: To obtain a coating solution for forming a protecting film capable of suppressing superposition of binders and uniformly dispersing MgO powder, etc., and usable for a stabilized flat panel display(FPD). SOLUTION: This coating solution for a FPD protecting film 14 is prepared by mixing a powder dispersing liquid and a binder solution. The powder dispersing liquid is prepared by mixing MgO powder or MgO powder whose surface is modified with fluorine, a solvent mainly composed of an alcohol or a mixed solvent of an alcohol and an ethylene glycol derivative and a dispersant mainly composed of an ethylene glycol derivative. The binder solution is prepared by mixing a binder mainly composed of a magnesium alkoxide or magnesium acetylacetonate and a solvent mainly composed of an alcohol or a mixed solvent of an alcohol and an ethylene glycol derivative and an additive mainly composed of an ethylene glycol derivative.
