(57) [Abstract] [Purpose] To provide a colored resist material comprising a photocurable resin, a pigment powder and a dispersant, which can be produced, used and developed by using water as a solvent. To do. [Structure] A copolymer of 2-hydroxyethyl methacrylate, (meth) acrylamide, and dialkylaminopropyl (meth) acrylamide as a photocurable resin, Alternatively, it is a copolymer obtained by adding an unsaturated carboxylic acid to 70% by weight of 2-hydroxyethyl methacrylate. A material that occupies the above is used, partially saponified polyvinyl acetate is used as a dispersant, and a carboxylic acid-containing aqueous solution having a carbon number of 2 to 6, which is solid at room temperature, is used as a developer. Further, a surfactant or a surfactant and acetylene glycol may be added to the developer. |
