    • A process for forming a polyimide composite electro-deposited film, which excels in durability of ink repelling function, wear resistance or mold-releasing property, has the following steps. An electrically conductive film is formed on at lest one side of a resin substrate. The polyimide composite electro-deposited film is formed on the electrically conductive film, while allowing co-deposition of at least one type of eutectic fine particles selected from the group consisting of water-repellant fine particles, wear-resistant fine particles and mold-releasing fine particles. This process can be used in the production of a nozzle plate having a discharge nozzle, by employing the water-repellant fine particles as the eutectic fine particles. When a metallic substrate is used, the polyimide composite electro-deposited film may be directly formed on one or both surfaces of such a metallic substrate.
    • 用于形成聚酰亚胺复合电沉积膜的方法具有以下步骤:其耐油墨性,耐磨损性或脱模性优异。 在树脂基板的至少一侧形成导电膜。 在导电膜上形成聚酰亚胺复合电沉积膜,同时允许至少一种选自疏水性细颗粒,耐磨细颗粒和脱模剂的共晶细颗粒共沉积 细颗粒。 通过使用疏水性细颗粒作为共晶细颗粒,该方法可用于制造具有排出喷嘴的喷嘴板。 当使用金属基板时,可以在这种金属基板的一个或两个表面上直接形成聚酰亚胺复合电沉积膜。
