Abstract: A photocurable resin composition includes a reactive monomer, a reactive oligomer, and a photopolymerization initiator. A cured product of the reactive monomer has a glass transition point of less than 20° C., and a cured product of the reactive oligomer has a glass transition point of less than 20° C. A cured product of the photocurable resin composition has a loss tangent tan ? at 25° C. of 0.2 or less. The cured product of the photocurable resin composition has an elongation at break in accordance with ASTM D638 of 150% or more.

Abstract: A photocurable resin composition includes: a first reactive compound that forms a glass phase through curing; a second reactive compound that is compatible with the first reactive compound and forms a rubber phase through curing; and a photopolymerization initiator. The first reactive compound includes at least a reactive monomer, and the second reactive compound includes at least a reactive oligomer. A polar term dP1 of Hansen Solubility Parameter of the first reactive compound and a polar term dP2 of Hansen Solubility Parameter of the second reactive compound differ by 1.8 or more.

Abstract: A nanometal ink capable of forming a metal film that exhibits good adhesion to a substrate and has low resistance. The nanometal ink is a baking-type nanometal ink, and contains metal nanoparticles, a polymerizable compound, a polymerization reaction initiator, a volatile liquid medium, and a dispersant. The polymerization reaction initiator is to be activated by the action of heat and/or light, to allow polymerization of the polymerizable compound to proceed. The dispersant includes a C6-14 alkylamine.
