Patent ID: 6899999

Claim:
A method of manufacturing a composite member having a conductive pattern, comprising: (1) forming on a surface of an insulating body a photosensitive layer containing both a photosensitive compound forming an ion-exchange group or causing an ion-exchange group to disappear upon irradiation with an energy beam and a crosslinkable compound having a crosslinkable group; (2) forming a pattern of ion-exchange groups by selectively exposing the photosensitive layer to an energy beam so as to form an ion-exchange group in the exposed portion or to cause an ion-exchange group to disappear from the exposed portion; (3) crosslinking the crosslinkable compound contained in at least the exposed portion of the photosensitive layer; (4) allowing metal ions, a metal compound, or a metal colloid to be adsorbed on the pattern of ion-exchange groups formed by the selectively exposing; and (5) forming a composite member having conductive pattern by depositing a conductive material on the pattern of ion-exchange groups having the metal ions, the metal compound, or the metal colloid adsorbed thereon using an electroless plating.
