Abstract: A fiber sheet impregnated with a resin composition mainly comprising poly-p-phenylene sulfide and having the degree of orientation of 0.3 to 0.9. The sheet is markedly improved in thermal resistance, thermal dimensional stability, dielectric characteristics and mechanical properties when folded, thus being suited for use as insulation base material for circuit boards and multilayer interconnection boards wherein higher-density and thinner circuits are necessitated.

Abstract: A thermoplastic polyester composition comprises a thermoplastic polyester prepared from an acid component mainly comprising an aromatic dicarboxylic acid and a glycol component mainly comprising an aliphatic glycol and a particulate mixture of two or more aluminium oxide components different from each other in crystal structure types, one of which is the &thetas;-type crystal structure. Since films formed from the compositions can have excellent slipping property, abrasion resistance and scratch resistance in repeated high-speed running, they are particularly suitable as substrates in magnetic recording media.
