<P>PROBLEM TO BE SOLVED: To provide a photocurable composition showing high conductivity, solvent resistance and flexibility of a cured product. <P>SOLUTION: A photocurable composition is prepared by combining a multifunctional vinyl compound having 3 or more functional groups, a monofunctional and/or bifunctional vinyl compound, and a conducting agent; and the prepared photocurable composition shows a storage modulus E' of 200 to 2,000 MPa in a rubbery region of a cured product in a dynamic viscoelasticity test measured at a temperature from -50°C to 250°C under the conditions of a temperature elevation speed of 5°C/min and a frequency of 10 Hz. The monofunctional and/or bifunctional vinyl compound may contain a chain aliphatic bifunctional (meth)acrylate having a chain aliphatic skeleton. The chain aliphatic skeleton may contain a unit derived from lactone and/or an aliphatic polyester unit. The monofunctional and/or bifunctional vinyl compound further may contain a ring-containing bifunctional (meth)acrylate having an alicyclic and/or aromatic skeleton. <P>COPYRIGHT: (C)2012,JPO&INPIT |
