摘要:
Disclosed herein is a front face erasable microcapsule magnetophoretic display sheet having a support and a solid dispersion layer provided on one surface of the support and composed of microcapsules having an average particle diameter of 50 to 650 μm, in which a liquid dispersion, a white pigment, additives and magnetic particles are encapsulated, and a binder. The magnetic particles include at least two kinds of magnetic particles different in particle diameter from each other. An erasing magnet for front face erasing and a writing magnet for front face erasable microcapsule magnetophoretic display sheet are also disclosed.
