    Abstract: PROBLEM TO BE SOLVED: To provide a dispersion liquid of microcapsules which contains microcapsules of a diameter of ≤4 μm at a low rate. SOLUTION: The microcapsule contains one or more lipophilic substances as core material and a polymer as a capsule shell obtained by radical polymerization of on oil in water emulsion containing 30-100 mass% of one or more 1-24C alkyl esters of acrylic acid and/or methacrylic acid (monomer I) based on the total mass of monomers, 0-80 mass% of a water insoluble of slightly soluble bifunctional or polyfunctional monomer (monomer II) based on the total mass of monomers, 0-40 mass% of other monomer (monomer III) based on the total mass of monomers, lipophilic substances, and inorganic solid particles having an average particle size of 45-1,000 nm.
