(57) [Problem] To provide a highly sensitive photosensitive resin composition and a curing method capable of performing chain curing by using visible light or ultraviolet laser light as a light source. SOLUTION: Upon irradiation with visible light or ultraviolet laser light, cations are generated inside the resin to cure the resin, and the heat of curing reaction is used to decompose the heat / photolysis type curing accelerator to generate cations. Along with the chain reaction, the reaction heat energy in the resin composition and the energy of the cations in the photosensitive resin composition so as to be chain-cured regardless of the presence or absence of an energy ray shield in the resin, a specific amount of (a) The above-mentioned photosensitive resin composition comprising: a cationic photopolymerization initiator (b) a heat / photodecomposition type curing accelerator (c); and one or more compounds capable of increasing the molecular weight by a cationic polymerization or a crosslinking reaction. |
