    • There are provided copper particles and a copper paste for a copper powder-containing coating film which can be subjected to electroless metal plating without using an expensive catalyst such as palladium, and a process for producing a conductive coating film by subjecting a copper powder-containing coating film formed by using the copper paste to electroless metal plating or heat treatment with superheated steam. The present invention relates to a process for producing a conductive coating film comprising the step of forming a coating film on an insulating substrate using copper particles having an average particle diameter of 0.05 to 2 μm as measured by observation using SEM in which a BET specific surface area value (SSA) (m2/g) and a carbon content (C) (% by weight) of the copper particles satisfy a relationship represented the following formula [1]: C/SSA·7×10−2 [1], and a copper paste comprising the copper particles; drying the coating film to obtain a copper powder-containing coating film; and then subjecting the resulting coating film to electroless metal plating or heat treatment with superheated steam.
    • 提供了铜颗粒和用于含铜粉末涂膜的铜浆,其可以在不使用钯等昂贵催化剂的情况下进行无电镀金属镀覆,以及通过使含铜粉末的 通过使用铜浆形成的涂膜通过无电镀金属镀层或用过热蒸汽进行热处理。 导电性涂膜的制造方法技术领域本发明涉及导电性涂膜的制造方法,其特征在于,包括以下步骤:使用平均粒径为0.05〜2μm的铜粒子,在绝缘性基材上形成涂膜, 铜颗粒的面积值(SSA)(m2 / g)和碳含量(C)(重量%)满足下式[1]所示的关系:C / SSA·7×10-2 [1] 以及包含铜颗粒的铜浆料; 干燥涂膜得到含铜粉末的涂膜; 然后对所得到的涂膜进行化学镀金属或用过热蒸汽的热处理。
