Procedure
More specifically, an intermediate transfer coating dispersion was prepared by providing a mixture of Special Carbon Black 4, available from Orion Chemicals, the solvent N-ethyl-2-pyrrolidone (NMP), the polyamic acid of biphenyl tetracarboxylicdianhydride/phenylenediamine, and the leveling agent NOVEC™ FC-4432, a fluoro surfactant available from 3M, about 18 weight percent of solids, and which mixture was stirred and subjected to ball milling with 2 millimeter stainless steel shots via an Attritor grinding mill for 18 hours at a speed of about 200 rpm for 48 hours. There resulted a coating dispersion of the polyamic acid of biphenyl tetracarboxylicdianhydride/phenylenediamine/carbon black/leveling agent contained in NMP, where the weight ratio of polyamic acid of biphenyl tetracarboxylicdianhydride/phenylenediamine/carbon black/leveling agent was 88.8/11/0.2, and which dispersion was filtered through a 20 micron Nylon cloth filter.
