A colored particle (e.g., a spherical particle) comprising an organic
solid component (e.g., a polymer component) and a coloring agent (e.g.,
an oil-soluble dye, and an organic or inorganic pigment) is produced by
eluting a water-soluble auxiliary component comprising at least an
oligosaccharide from a composition having a disperse system, in which a
particulate dispersed phase comprising the organic solid component and
the coloring agent is dispersed in a matrix comprising the auxiliary
component. The weight ratio of the polymer component relative to the
auxiliary component may be about 55/45 to 1/99. The proportion of the
coloring agent may be about 0.001 to 100 parts by weight relative to 100
parts by weight of the organic solid component. Such a process ensures
conveniently and industrially advantageous production of a colored
particle (e.g., a colored polymer particle) corresponding to the
dispersed phase independently of affinity between the dispersed phase and
the matrix.
