<p>PURPOSE:To provide a composition which can give an organic thick film resistance element excellent in stability, etc., by dispersing a thermosetting resin comprising a tetracarboxylic acid dianhydride, diaminodiphenylmethane, a lactam compound and carbon in a dispersing medium such as an alcohol. CONSTITUTION:A thermosetting resin composed of tetracarboxylic acid dianhydrides of formula I and/or, diaminodiphenylmethane and/or diaminodiphenyl sulfone and a lactam compound (e.g., gamma-butyrolactam) and carbon (e.g., acetylene black) are dispersed in a dispersing medium such as an alcohol and/or a ketone. The obtained paste 16 is applied between electrodes 14 and 14 provided on a substrate 10 to form an organic thick film resistance element. In this way, a resistance element which scarcely suffers any change in its resistance value even when subjected to long-term heating can be obtained.</p> |
