PURPOSE:To provide the titled compsn. having thixotropic properties suitable for coating by a dispensing method, by adding a specified alkylenebis (aliph. monocarboxylic acid amide) to a polyimide precursor soln. contg. an electrically conductive filler. CONSTITUTION:150-1,900pts.wt. electrically conductive filler having a particle size of 100 mesh or below (e.g. silver powder) is blended with 100pts.wt. (on a solid basis) soln. of a polyimide precursor having an intrinsic viscosity of 0.3- 3.0, composed of 0.1-50mol% of a repeating unit of formula I (wherein R is a bivalent hydrocarbon group; R' is a monovalent hydrocarbon group; n is at least 1) obtd. by reacting a diaminosiloxane, an org. diamine contg. no Si atom and a tetracarboxylic acid dianhydride and 99.9-50mol% of a repeating unit of formula II (wherein R'' is a tetravalent org. group; R''' is a bivalent org. group which is a residue of an org. diamine contg. no Si atom). 0.5-5wt% alkylenebis (aliph. monocarboxylic acid amide) of formula III (wherein R1 and R2 are each a 6- 24C monovalent hydrocarbon group; R3 is a 1-6C bivalent hydrocarbon group) is added to the resulting soln.
