Abstract: A method for producing pressure-responsive particles includes: adding an aggregating agent and a dispersion containing silica particles to a dispersion containing composite resin particles containing a styrene-based resin including a styrene compound and a vinyl monomer other than the styrene compound as polymer components and a (meth)acrylic acid ester-based resin including a (meth)acrylic acid ester compound as a polymer component to cause aggregation so as to form aggregated particles; and heating and fusing the aggregated particles to form pressure-responsive particles. The amount of the silica particles added by the dispersion containing the silica particles is 0.5 mass % or more and 10 mass % or less relative to a total mass of the composite resin particles. The mass ratio of the styrene-based resin to the (meth)acrylic acid ester-based resin in the pressure-responsive particles is from 80:20 to 20:80. A difference between the lowest glass transition temperature and the highest glass transition temperature of resins contained in the pressure-responsive particles is 30° C. or more.
