| abstract |
A method for producing pressure-responsive particles includes: adding an aggregating agent 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 aggregate the composite resin particles so as to form aggregated particles A; forming a shell by adding an aggregating agent and styrene-based resin particles containing a styrene compound and a vinyl monomer other than the styrene compound as polymer components to a dispersion containing the aggregated particles A to aggregate the styrene-based resin particles so as to form aggregated particles B; and heating and fusing the aggregated particles B to form pressure-responsive particles. The amount of the styrene-based resin particles added in the formation of the shell is 5 mass % or more and 40 mass % or less relative to the total mass of the composite resin particles. The amount of the aggregating agent added in the formation of the shell is 0.1 mass % or more and 1.0 mass % or less relative to the 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. |
