The present invention provides a protecting film capable of preventing deterioration in adhesion and matching to a substrate (dielectric layer), and deterioration in electric insulation. The protecting film includes a film body composed of MgO or the like which is inhibited from reacting with CO gas and H O gas in air to prevent degeneration of MgO or the like into MgCO and Mg(OH) , etc. harmful to FPD. The film body is formed on the surface of the substrate, and the fluoride layer is formed on the surface of the film body. The fluoride layer is represented by MO F (M is Mg, Ca, Sr, Ba, an alkali earth complex metal, a rare earth metal, or a complex metal of an alkali earth metal and a rare earth metal, 0&lE;X<2, and 0<Y&lE;4), and is obtained by reaction of a gaseous fluorinating agent with MaO or the like. As the gaseous fluorinating agent, a fluorine gas, a hydrogen fluoride gas, BF , SbF or SF is preferably used.

Polyhedral organosilicon compound and method for producing the same

A hydrophobic metal oxide powder obtained by simultaneously surface-treating a powder of a metal oxide (for example, silica, titania, alumina, or the like) with silicone oil having epoxy groups and a non-polymeric amine compound having a lower number of primary and/or secondary amino groups than the number required for reaction with all epoxy groups, or surface-treating the powder with silicon oil having epoxy groups and amino groups and previously obtained by reaction. Straight silicone oil may be further used for surface treatment. Frictional charge which is controlled within a wide range of from negative charge to positive charge, high hydrophobicity and fluidity can be imparted to the powder by using a relatively small amount of coating, and a hydrophobic metal oxide powder useful as an additive for an electrophotographic developer can be obtained.
