摘要

A method of producing organic nanoparticles, comprising: mixing a solution of an organic material dissolved in a good solvent with a solvent that is compatible with the good solvent but is a poor solvent for the organic material, to prepare a dispersion in which the organic material is being formed to organic fine particles of a size in the order of nanometer; wherein the dispersion contains a polymer compound having a weight-average molecular weight of 1,000 or more represented by the following formula (1): wherein R1 represents a (m+n)-valent connecting group; R2 represents a single bond or a divalent connecting group; A1 represents a specific monovalent organic group; when n is two or more, plural A1s may be the same or different; m represents 1 to 8; n represents 2 to 9; m+n is 3 to 10; and P1 represents a polymer compound residue.
