PURPOSE: To obtain the present composition outstanding in storage stability and resistance to environment, by blending an electrically conductive coating component made up of copper powder, resin binder and solvent with a mixture, as the dispersant, of titanium acylate polymer and higher saturated fatty acid ester.
CONSTITUTION: The objective electrically conductive composition comprising (A) copper powder, (B) a resin binder (e.g., acrylic resin, polyester resin), (C) a mixture of C1: 20W80wt.% of a titanium acylate polymer, i.e., a condensate of at least dimer having recurring unit(s) of formula I, II and/or III (R' is 1W10C hydrocarbon group; R1WR3 are each 1W17C hydrocarbon group; l>1, m>1, n≥1) and C2: 80W20wt.% of a higher saturated fatty acid ester, pref. a compound of formula IV (R is 1W17C hydrocarbon group; R1 is 1W10C hydrocarbon group) (D) a solvent in such amounts as to be, based on the weight of the final composition except the component D, 40W90wt.%, 10W60wt.% and 0.05W10wt.% for the components A, B and C, respectively, with the component A covered with 0.1W10wt.% of the component C (based on the component A).
