Abstract: The present invention relates to a resin surface treating agent containing as an effective component at least one cerium compound selected from tetravalent and trivalent cerium compounds. The surface treating method of the present invention is a method of bringing a surface of a resin into contact with a surface treating agent containing as an effective component at least one cerium compound selected from tetravalent and trivalent cerium compounds, and thereafter treating the surface with an acidic aqueous solution. This activates the resin surface and thereby increases a strength of adhesion of, for instance, a polyimide-based resin film with metal wires, as well as a strength of adhesion of a polyimide-based resin film with another resin. Thus, a resin surface treating agent that provides excellent productivity and reduces processing costs, as well as a surface treating method using the same, are provided.

Abstract translation: 本发明涉及含有至少一种选自四价和三价铈化合物的铈化合物作为有效成分的树脂表面处理剂。 本发明的表面处理方法是使树脂的表面与含有选自四价和三价铈化合物的至少一种铈化合物作为有效成分的表面处理剂接触，然后用 酸性水溶液。 这激活树脂表面，从而增加例如具有金属线的聚酰亚胺系树脂膜的粘合强度，以及聚酰亚胺系树脂膜与其他树脂的密合强度。 因此，提供了提供优异的生产率和降低加工成本的树脂表面处理剂，以及使用该树脂表面处理剂的表面处理方法。
