PROBLEM TO BE SOLVED: To prevent deformation of a resistance pattern and to improve workability and curing characteristics by compounding a cyclic aliphatic epoxy resin, a cationic photoinitiator, a thermosetting catalyst and an electroconductive particle. SOLUTION: Into 100 pts.wt. of a cyclic aliphatic epoxy resin of the formula: R-M-R' are incorporated 1-10 pts.wt., 2-5 pts.wt. in particular, of a cationic photoinitiator selected among onium salts and organic metal salts, 1-5 pts.wt. of a thermosetting catalyst, 1-90 pts.wt. of an electroconductive particle, and if required, 0.01-1 pt.wt. of a coupling agent, 0.01-10 pts.wt. of a binder and 1-20 pts.wt. of a reactive diluent having a viscosity of 1-20 cP. In the formula, R and R' are each cyclohexylepoxide, methylcyclohexylepoxide or ethylepoxide; at least one of R and R' is cyclohexylepoxide or methylcyclohexylepoxide; and M is -CO-O-CH2- or -CH2-CO-C4H8-CO-O-CH2-. |
