| 20090020043 | METHOD FOR MANUFACTURING DISPERSION OF QUINOLINE DERIVATIVE - A method for manufacturing a dispersion of a quinoline derivative that is dispersed at a high concentration and has a small particle size. The method includes the steps of preparing a solution by dissolving an N-arylanthranilic acid derivative in an organosulfonic acid, heating the solution and obtaining a reaction liquid in which a quinoline derivative has been produced by a condensation ring-closing reaction, and obtaining a dispersion of the quinoline derivative by mixing the reaction liquid with an aqueous solution. The step of mixing the reaction liquid with an aqueous solution may be performed in a mixing field having a micro-channel. | 01-22-2009 |
| 20090025603 | PIGMENT INK COMPOSITION AND COATING MATERIAL - A pigment ink composition has high transparency and good color characteristics such as a high OD that are not inferior to those of dyes, even though pigment particles are used, and also has good weatherability and remaining ability on the coating and printing medium surface that are inherent to pigment particles. The pigment ink composition contains pigment particles including at least needle pigment particles, a dispersant, and a solvent. The needle pigment particles have a needle shape with an aspect ratio of at least 3, an average aspect ratio of at least 5 and at most 7, an average short dimension of at least 20 nm and at most 30 nm, and a distribution of short dimension with a standard deviation of 2.0 nm or less. The needle pigment particles are covered with the dispersant. | 01-29-2009 |
