Abstract:
1. A process for the production of a laminate, said process comprising forming on a polyimide substrate a polyimide resin precursor layer by coating and drying a polyimide resin precursor solution in which a palladium compound is uniformly dispersed in a polyimede resin precursor and said palladium compound and said polyimide resin precursor together form a complex; forming nuclei for primer plating by subjecting the polyimide resin precursor layer to ultraviolet irradiation in the presence of a hydrogen donor, and then forming a metal primer layer on the nuclei for primer plating through electroless plating treatment; and further forming a surface plating layer on the metal primer layer; wherein before or after the surface plating layer is formed, the polyimide resin precursor layer is subjected to imidation by heating and is made into a polyimide resin layer.
