Abstract: Pressure-responsive particles include pressure-responsive base particles and fatty acid metal salt particles, in which the pressure-responsive base particles contain a styrene-based resin which contains styrene and other vinyl monomers as polymerization components and a (meth)acrylic acid ester-based resin which contains at least two kinds of (meth)acrylic acid esters as polymerization components and in which amass ratio of the (meth)acrylic acid esters to all polymerization components is 90% by mass or higher, the pressure-responsive particles have at least two glass transition temperatures, and a difference between the lowest glass transition temperature and the highest glass transition temperature is 30° C. or higher.
