摘要： There is proposed a method of curing an electromagnetic radiation-curing type liquid composition comprising a solvent polymerizable in the presence of an acid, and a photo-acid generating agent which is dissolved in the solvent and capable of generating the acid when irradiated with electromagnetic radiation. This method comprises forming a layer of the electromagnetic radiation-curing type liquid composition on a recording medium, and irradiating electromagnetic radiation including a wavelength which can be absorbed by the photo-acid generating agent onto the composition layer to generate the acid from the photo-acid generating agent, thereby curing the composition layer, which is characterized in that the recording medium is heated on the occasion of forming the layer of the electromagnetic radiation-curing type liquid composition in such a manner that the temperature of the recording medium is increased higher than the temperature of the electromagnetic radiation-curing type liquid composition being delivered onto the recording medium.
