摘要:
Silica-including microcapsule resin particles including an outer shell constituted of a crosslinked polymer and a cavity partitioned with the outer shell, in which the silica-including microcapsule resin particles contain inside the cavity a porous structure in which silica particles are mutually connected, and have a volume average particle diameter of 0.5 to 100 μm.
