Abstract: A method for producing a liquid dispersion of composite resin particles includes polymerizing a styrene compound and an extra vinyl monomer together to give a styrene resin; polymerizing a (meth)acrylate compound in the presence of the styrene resin to give intermediate resin particles A, which are resin particles containing the styrene resin and a (meth)acrylate resin; polymerizing a styrene compound and an extra vinyl monomer in the presence of intermediate resin particles A to give liquid dispersion B, which is a liquid dispersion containing intermediate resin particles B; and adding a polymerization initiator to liquid dispersion B to give a liquid dispersion containing composite resin particles. In the composite resin particles as a whole, the ratio by mass between the styrene and (meth)acrylate resins is between 80:20 and 20:80. There is a difference of 30° C. or more between the lowest and highest glass transition temperatures of the composite resin particles.

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.
