METHOD FOR PRODUCING COMPOSITE MEMBER, PHOTOSENSITIVE COMPOSITION AND POROUS BASE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a composite member in which a wiring pattern is formed on a base material of an insulator by which a fine three-dimensional pattern can be formed at a low cost without dissolving and peeling a photosensitive layer by a plating solution. SOLUTION: The method is provided with (1) a stage where a photosensitive layer containing a photosensitive compound which produces or loses an ion exchangeable group by the irradiation of an energy ray and a crosslinkable compound having a crosslinkable group is formed on an insulator; (2) a stage where the photosensitive layer is pattern-exposed, and on the exposed part, the ion-exchangeable group is produced or lost to form a pattern of the ion exchangeable group; (3) a stage where the crosslinkable compound of the photosensitive layer at least in the exposed part is crosslinked; (4) a stage where a metallic ion or a metallic colloid is adsorbed on the pattern of the ion- exchangeable group formed by the above pattern exposure; and (5) a stage where the pattern of the ion-exchangeable group with the metallic ion or metallic colloid adsorbed is subjected to electroless plating to form an electrically conductive pattern.
