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
Abstract:
The present invention provides a carbon black-dispersed polyamic acid solution composition having a high solids content and a high carbon black content. The invention further provides an intermediate transfer belt using the polyamic acid solution composition. The carbon black-dispersed polyamic acid solution composition is obtained by uniformly dispersing carbon black in a polyamic acid solution obtained by reacting biphenyltetracarboxylic dianhydride and an aromatic diamine in an organic polar solvent. The biphenyltetracarboxylic dianhydride includes 2,3,3′,4′-biphenyltetracarboxylic dianhydride and 3,3′,4,4′-biphenyltetracarboxylic dianhydride. The aromatic diamine includes 4,4′-diaminodiphenyl ether and p-phenylenediamine. The polyamic acid solution has a solids content of 25 weight % or more.
Abstract(Chinese):

本发明提供一种具有高固体含量和高炭黑含量的炭黑分散聚酰胺酸溶液组合物。 本发明还提供了使用聚酰胺酸溶液组合物的中间转印带。 炭黑分散的聚酰胺酸溶液组合物通过将炭黑均匀分散在通过联苯四羧酸二酐和芳族二胺在有机极性溶剂中反应获得的聚酰胺酸溶液中而获得。 联苯四羧酸二酐包括2,3,3'，4'-联苯四羧酸二酐和3,3'，4,4'-联苯四羧酸二酐。 芳族二胺包括4,4'-二氨基二苯醚和对苯二胺。 聚酰胺酸溶液的固体含量为25重量％以上。
