Abstract
An active energy ray-curing resin composition comprises: (i) a linear polymer having a glass transition temperature of 50.degree. C. or higher and a weight average molecular weight of about 3.0.times.10.sup.4 or higher; (ii) a monomer having an ethylenically unsaturated bond; (iii) an epoxy resin comprising at least one compound having one or more epoxy groups in the molecule; and (iv) a polymerization initiator capable of generating a Lewis acid by irradiation with an active energy ray.
