Disclosed is a photocurable adhesive composition which, in the lamination of a decorated plate or an icon sheet on a touch panel or in the lamination of a transparent substrate with a transparent electrode formed thereon on a transparent plate in an electrostatic capacitive touch panel, can impart satisfactory adhesive properties and can realize the lamination without incorporating air bubbles. Also disclosed is a photocurable resin composition for use in the lamination of a display and an optically functional material on each other, which, when a display is laminated on an optically functional material, does not cause the delamination of a bonded surface or the breaking of a glass in the display. The photocurable adhesive composition comprises (A) a (meth)acrylate oligomer having a polyisoprene, polybutadiene, or polyurethane skeleton, (B) a softening component, and optionally (C) (C1) a (meth)acrylate monomer selected from phenoxyethyl(meth)acrylate, phenoxy polyethylene glycol(meth)acrylate, 2-hydroxy-3-phenoxypropyl(meth)acrylate, and cyclohexyl(meth)acrylate, (C2) or a thiol compound. The photocurable resin composition can provide a cured product having a modulus of elasticity and an elongation at break both of which fall within given ranges. |
