Abstract: A fiber-reinforced composite material superior in mechanical strength, heat resistance and hot water resistance is provided herein. This composite material is composed of a matrix of a cured product of a resin composition containing as essential components an epoxy resin (A) and an imide compound (B) represented by the following general formula (I), ##STR1## wherein X represents --NH.sub.2 group and/or --OH group, Ar represents an aromatic residue, R.sub.1 represents a hydrogen atom or an alkyl group having from 1 to 10 carbon atoms, R.sub.2 represents a hydrogen atom, an alkyl or alkoxy group having from 1 to 20 carbon atoms or a hydroxyl group, and each of m and n cannot be 0 at the same time, and a fiber (C) as a reinforcing material.

Abstract: A composition for forming a transparent conductive film obtained by mixing an organic solution comprising an indium salt of inorganic acid and a tin salt of an inorganic acid with a non-aqueous silica sol. The composition of the present invention shows excellent stability with a lapse of time and good wettability to a substrate plate. A transparent conductive film obtained shows a strong adhesion strength to a substrate plate and has a two-layered structure.
