PURPOSE:To obtain an electrically conductive ink composition excellent in adhesion to insulating silicone rubbers by blending a curable composition containing an organopolysiloxane, a crosslinking agent and electrically conductive carbon particles with a specific silazane compound. CONSTITUTION:An electrically conductive ink composition is obtained by blending (A) a curable composition containing (i) an organopolysiloxane having preferably >=2 alkenyl groups in one molecule and 100-200000cSt viscosity at 25 deg.C, (ii) a cross-linking agent which is an organohydrogenpolysiloxane having preferably >=2 hydrogen atoms bonded to silicon atom in one molecule and (iii) electrically conductive carbon particles with (B) a silazane compound expressed by the formula [R<1>, R<2> and R<3> are (un)substituted monofunctional hydrocarbon group]. The aforementioned ink composition is suitable for producing contact parts such as keyboards of electronic calculators, personal computers or telephone sets. |
