Japanese Patent JP2022111034

A

To provide pressure-responsible particles which are excellent in adhesion to peelably bond surfaces of a recording medium.SOLUTION: Pressure-responsible particles contain pressure-responsible base particles containing a (meth)acrylate-based resin that contains a styrenic resin containing styrene and other vinyl monomer as polymerization components and at least two (meth)acrylate as polymerization components, and has a mass ratio of (meth)acrylate occupied in the entire polymerization components of 90 mass% or more, and silica particles, has at least two glass transition temperatures and a difference between the lowest glass transition temperature and the highest glass transition temperature of 30°C or higher, wherein a ratio of a surface coverage Cs1 by silica particles before stress is applied to a surface coverage Cs2 by the silica particles after a first stress has been applied satisfies a relation of 0.4≤Cs2/Cs1≤0.8.SELECTED DRAWING: None
