According to the present invention, a resist resin having in its structure a specific bridged-bond-containing aliphatic ring, and a resist composition comprising the same are provided. By using this resist composition, a resist pattern excellent in both transparency against short-wavelength light and dry-etching resistance can be formed by alkali development with high resolution.

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.

There is proposed a washing solution for washing an inkjet printer head which performs printing by feeding an ink comprising at least two kinds of polymerizable compounds each differing in viscosity, a photopolymerization initiator, and pigment. This washing solution is characterized in that it contains not less than 50 parts by weight of a polymerizable compound selected from the polymerizable compounds included in the ink and having a lowest viscosity among the polymerizable compounds, or not less than 50 parts by weight of a polymerizable compound having a viscosity of 30 mPa·sec or less at ordinary temperature.
