Page/Page column 6, (2009/02/11)
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.
