A method for manufacturing a microstructure comprising cured products of photosensitive resin compositions, the method comprising: a step of forming at least two layers of the photosensitive resin compositions each comprising a photopolymerization initiator; a step of subjecting each of the formed at least two layers of the photosensitive resin compositions to patterning exposure; and a step of collectively developing the exposed at least two layers of the photosensitive resin compositions to obtain a microstructure, wherein in the at least two layers of the photosensitive resin compositions, 90% by mass or more of the photopolymerization initiators contained in at least one of the two adjacent layers of the photosensitive resin compositions is a nonionic photopolymerization initiator.

Method for manufacturing microstructure including cured products of photosensitive resin compositions

There is provided an epoxy resin composition containing an epoxy resin, a solid basic compound, and a polythiol. By preparing a mixture 1 by kneading the epoxy resin with the solid basic compound, and then kneading the polythiol therewith, the dissolution of the solid basic compound into the polythiol is rate-limited to ensure the pot life, and due to a catalyst action by the dissolution of the solid basic compound at a time of heating, heat curability in a short time is realized.

Method for producing epoxy resin composition

There is provided an epoxy resin composition including: an epoxy resin, a thixotropic agent, a photobase generator, and an ether skeleton polythiol.
