发明名称 FINE PARTICLES AND METHOD OF PRODUCING THEREOF, FINE PARTICLE DISPERSION LIQUID, AND IMAGE DISPLAY MEDIUM AND IMAGE DISPLAY APPARATUS
摘要 <p>An object of the present invention is to provide white colored fine particles with high white reflectance and not easily precipitating in a dispersion medium compared to inorganic white pigments, a method of producing the fine particles, an image display medium and an image display apparatus having a high whiteness like a paper and an excellent display memorability using the fine particles. Therefore, the fine particles contain a polymer of a compound expressed by the following formula (1). In the above formula (1), R represents a hydrogen atom, a halogen atom, an alkyl group or an alkenyl group, "m" represents an integer of 1 to 10, and at least one of R represents the alkenyl group.</p>
