    摘要： Disclosed is an optical device which can be formed as a thinner layer by a simplified manufacturing process at a reduced cost. Specifically, the optical device has a multilayer structure wherein a polyvinyl alcohol- or polyvinylene-base polarizing film (b) and protective films (a and c) are directly laminated on top of another without any adhesive layer including a pressure sensitive adhesive layer interposed therebetween. The protective film (c) on one side is composed of a triacetyl cellulose, an alicyclic polyolefin resin, or an alicyclic acrylic resin, and the protective film (a) on the other side is composed of a triacetyl cellulose, a polycarbonate, a polyethylene terephthalate, a polyethylene naphthalate, a (meth)acrylate resin, an alicyclic polyolefin resin, or an alicyclic acrylic resin.

    摘要： This invention aims to make it possible to obtain curing surfaces with different surface free energies, and to provide a method of curing an ionizing radiation curing resin composition which can be used as a coating material. Further, it aims to provide a surface modification method which permits surfaces of different surface free energy to be obtained. The above object is achieved by a method of curing a mixture comprising an ionizing radiation curing resin, characterized in that at least part of a mixture comprising 0.01-10 weight parts of a compound (b) having a surface free energy not exceeding 25 mN/m relative to 100 weight parts of an ionizing radiation curing resin composition (a) having a surface free energy of at least 30 mN/m, is cured by irradiating it with ionizing radiation in contact with a medium having a surface free energy higher than that of the ionizing radiation curing resin composition (a).
