Abstract
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).
