ELECTROCONDUCTIVE INK, ELECTROCONDUCTIVE CIRCUIT AND NON-CONTACT TYPE MEDIUM

PROBLEM TO BE SOLVED: To provide an ink suitable to the formation of a circuit pattern such as an electroconductive circuit, which contains an electroconductive substance capable of conducting accurate printing and also contains a compound polymerizable with an active energy ray. SOLUTION: The electroconductive ink curable with an active energy ray containing an electroconductive substance and a binder, which comprises, as a binder, a phosphoric acid ester compound such as a reaction product of anhydric phosphoric acid and a 6-hexanolide addition polymer of acid phosphoxy ethyl methacrylate, acid phosphoxy propyl methacrylate, acid phosphoxy polyoxyethylene glycol monomethacrylate, acid phosphoxy polypropylene glycol monomethacrylate or 2-hydroxyethyl methacrylate and a reaction product of 2-hydroxyethyl methacrylate and anhydric phosphoric acid, and a compound polymerizable with an active energy ray.
