| 摘要 |
A primer composition comprising (A) a solvent-soluble polyorganosiloxane consisting essentially of R1SiO3/2 units and R1SiO units in a specific ratio, (B) an organosiloxane and/or a partial hydrolysis condensate thereof, the organosiloxane having more than two silicon-bonded hydrolyzable groups per molecule, (C) an electroconductive filler, (D) a curing catalyst, and (E) an organic solvent. The primer composition shows good coating properties and excellent storage stability. Primer film obtained from the primer composition has various excellent properties such as adhesiveness, electroconductivity, heat resistance and moisture resistance.
