Abstract

PURPOSE:To obtain porous particles that are destructible by low pressure and excellent in pressure fixity by removing hydrophobic solvent from a mixture prior to the process of obtaining dry powder in manufacturing porous particles from particles containing hydrophobic solvent. CONSTITUTION:When manufacturing porous particles by dispersing a mixture made by dissolving or dispersing a soluble compound and coloring agent in a hydrophobic solvent in water, the most part of the hydrophobic solvent is removed in a process from dispersion in water to dry powder. By this way, the volume occupied by the hydrophobic solvent becomes void, and consequently, porous particles destructible by low pressure and excellent in pressure fixity are obtained.
