Abstract
A particle set for producing a printed matter includes: a chromatic color toner containing toner particles A; and pressure-responsive particles containing base particles B, in which the base particles B contain a styrene resin containing, as polymerization components, styrene and a vinyl monomer other than styrene, and a (meth)acrylate resin containing, as a polymerization component, a (meth)acrylate, a mass ratio of the styrene resin to the (meth)acrylate resin (styrene resin:(meth)acrylate resin) is 80:20 to 20:80, a difference between the lowest glass transition temperature and the highest glass transition temperature of the pressure-responsive particles is 30° C. or more, and when the toner particles A have a volume average particle diameter D50A and the base particles B have a volume average particle diameter D50B, the D50A and the D50B satisfy formula 1-1: 1.5 μm<(D50B−D50A).
