Electrically conductive elements, such as imaging elements, can be prepared by applying electrically conductive coating compositions to a suitable support. The coating compositions include a polyaniline-protonic counter-ion complex in a first solvent that has certain Hansen solubility parameters, and a film-forming binder in a second common coating solvent. The total solids in the coating composition is less than or equal to 10 weight %, and the weight ratio of the binder to the complex is at least 1:1. Under these formulation conditions, the polyaniline protonic counter-ion complex is solubilized, rather than being in dispersed form, and is readily applied to form a thin, relatively transparent, electrically conductive film. Antistatic layers of photographic elements can be prepared in this manner.
导电元件,如成像元件,可通过将导电涂层组合物涂在合适的支架上制备。涂层组合物包括在具有一定汉森溶解度参数的第一种溶剂中的聚苯胺-质子反离子复合物,以及在第二种普通涂层溶剂中的成膜粘合剂。涂层组合物中的总固体含量小于或等于 10 重量%,粘合剂与络合物的重量比至少为 1:1。在这些配制条件下,聚苯胺质子反离子络合物被溶解,而不是以分散的形式存在,并且很容易涂抹形成一层薄的、相对透明的导电薄膜。照相元件的抗静电层可以用这种方法制备。
