This invention relates to a sealing glass for use in bonding glass, ceramics and metals and specifies the composition of a sealing glass which is workable at moderate temperatures and is excellent in transparency and strength. Amorphous magnetic materials have themselves a crystallization temperature and when used in a magnetic head, the amorphous materials undergo crystallization in assembling the head at a sealing temperature higher than the crystallization temperature and becomes not only brittle but also deteriorated in magnetic characteristics so that the head becomes unsuitable for use. The present glass is advantageously used in such a case.

[Purpose] An object of the present invention is to provide a composition for use in a formation of transparent and electrically conductive film having a low electric resistance and a high transmittance and a method for making the film mentioned above. [Composition] A mixture of inorganic indium compound and organic tin compound is combined with organic compound capable of coordinating with either of indium and tin to form an organic solution. When the mixture is heated, the inorganic indium compound and the organic tin compound coordinating partially with the organic compound react with water of crystallization of inorganic indium compound. The organic tin compound is partially subjected to hydrolysis to form an intermediate complex compound including indium and tin. This suppresses the evaporation of tin and generates a uniform film having a high transmittance and a low electric resistance. An addition of polyhydric alcohol increases the viscosity of the solution and gives a high stability to a resultant film obtained by applying the composition to the substrate and firing.

The composite layer according to the present invention comprises a substrate and a colored layer formed on the surface of this substrate. This colored layer contains a transparent layer and a coloring agent dispersed within the transparent layer, and this transparent layer is made of an inorganic gel or glass material, while the coloring agent contains dyes or pigments. The composite layers of the present invention are suitable for use in products such as construction materials with the appearance of marble, colored glass materials for decorative purposes, or color filters.

@ The present invention relates to an article having an insulation abrasion-resistance coated layer composed of glass ceramics containing a given amount or more by weight at least either of oxides of divalent alkaline earth metals of a group composed of BaO, MgO, CaO and ZnO and containing a given amount or less the oxides of univalent alkali metal of a group composed of Na 2 O, K 2 0 and Li 2 O on the surface of the metallic base body. As it may be used in bearing, mechanical seal and tape guide post, the abrasion-resistance of the sliding portion may be improved.
