摘要： Provided is a colored resin fine particle water base dispersion liquid which can be a base material for an ink causing no precipitates and having storage stability. Further provided is a water base ink composition for an ink jet recording apparatus or a water base ink composition for a writing tool capable of providing recorded images or written characters and drawn lines which are clear and neither are blurred nor disappear due to water and sweat and which are so excellent in light fastness that they are not deteriorated over a long period of time, wherein the colored resin fine particle water base dispersion liquid is produced by mixing a water soluble basic dye with a mixed vinyl monomer containing a vinyl monomer having an acid functional group and emulsion-copolymerizing the above mixture.

摘要： A medium for electrophoretic display using a liquid for electrophoretic display which can reversibly change a visible state by action of an electric field includes a medium comprising each independent structures of microcapsules or cells filled with a liquid for electrophoretic display comprising at least alkylpolyetheramine having a structural unit represented by a specific structural formula, one or more kinds of fine particles, a dispersant and a dispersion liquid medium, wherein the fine particles contain fine particles subjected to surface treatment for making lipophilic. Also, an electrophoretic display device includes a display device comprising a pair of substrates in which a light-transmitting electrode is formed on at least one substrate and the medium for electrophoretic display described above between the substrates.The electrophoretic display medium and the electrophoretic display device each using the above display liquid for electrophoretic display have a high contrast on a display face and can display the contrast with high reliability even in repetitive display, and they are excellent as well in a response.

摘要： Provided is a stable water base ink composition which has a sufficiently high concentration as ink for an ink jet-recording apparatus and writing instruments and prevents the recorded images and the written characters from being blurred or disappearing with water and sweat and which has such an excellent light fastness that the images and the characters do not deteriorate over a long period of time and does not cause a change in physical properties and precipitates. A water base dispersion liquid containing colored resin fine particles is prepared by emulsion-polymerizing a vinyl monomer in the presence of a hydrophobic dye and then diluted with water or a water soluble organic solvent, whereby the water base ink composition is produced.
