<p>PURPOSE:To obtain a silicon ink having an excellent storage stability as well as high electric conductivity and colorability by compounding an addition-curable polyorganosiloxane, a specific carbon black, and a solvent. CONSTITUTION:An addition-curable polyorganosiloxane, a carbon black having an iodine adsorption of 50mg/g or lower, a primary particle diameter of 35mu or higher, and a DBP absorption of 150ml/100g or higher, and a solvent are compounded as effective components to give a silicone ink. Carbon black is classified into a thermal black, a furnace black, an acetylene black, etc., by the preparation method and qualities; in the invention, the acetylene black is pref. when electric conductivity is important, and the furnace black, when coloring power is emphasized.</p> |
