METHOD OF MANUFACTURING PARTICLE HAVING OPTICAL REFLECTANCE AND ELECTROSTATIC CHARGING PROPERTY, PARTICLE HAVING OPTICAL REFLECTANE AND ELECTROSTATIC CHARGING PROPERTY, AND INFORMATION DISPLAY PANEL

摘要

PPROBLEM TO BE SOLVED: To obtain a composite structure particle in which embedded depth of sub-particles in the surface of a main particle is uniform by setting a suitable temperature condition in each of coating step and a composition step. PSOLUTION: Each of particles composing a display medium which is sealed into a space between substrates of an information display panel and having optical reflectance and an electrostatic charging property is a composite particle obtained by arraying a plurality of sub-particles on the surface of one main particle. In a composite structure particle obtained by embedding and fixing sub-particles in a uniformly coated state on the surface of the main particle composed of resin as a main component, the set temperature T1 of the coating step for forming a state of uniformly coating the sub-particles on the surface of the main particle is set to a temperature lower than a softening point of a resin material of the main particle, and the set temperature T2 of the composition step for embedding and fixing the sub-particles on the surface of the main particle is set to a temperature higher than the set temperature T1, and at which a material composing the sub-particles is not softened.
