POLYAMIC ACID SOLUTION COMPOSITION HAVING CARBON BLACK DISPERSED THEREIN, PROCESS FOR PRODUCTION OF SEMICONDUCTIVE POLYIMIDE RESIN BELT USING THE COMPOSITION, AND SEMICONDUCTIVE POLYIMIDE RESIN BELT

摘要

Disclosed is a polyamic acid solution composition having carbon black dispersed therein, which has a high solid content and a high carbon black content. Also disclosed is an intermediate transfer belt produced by using the polyamic acid solution composition. Specifically disclosed is a polyamic acid solution composition having carbon black dispersed therein, which comprises a polyamic acid solution and carbon black dispersed in the polyamic acid solution homogeneously, wherein the polyamic acid solution is produced by reacting a biphenyltetracarboxylic acid dianhydride component with an aromatic diamine component in an organic polar solvent, wherein the biphenyltetracarboxylic acid dianhydride component comprises 2,3,3',4'-biphenyltetracarboxylic acid dianhydride and 3,3',4,4'-biphenyltetracarboxylic acid dianhydride, wherein the aromatic diamine component comprises 4,4'-diaminodiphenylether and p-phenylenediamine, and wherein the polyamic acid solution has a solid content of 25 wt% or more.
