Electrical circuitry is produced on the surface of an organic polymer. The electrical circuitry is produced on a support, and a polymerizable composition is brought into contact with the support and the circuitry. The polymerizable composition is polymerized while in contact with support and the circuitry to produce a solid, organic polymer.
