MICROPARTICLE, PROCESS FOR PRODUCING MICROPARTICLE, AND, LOADED WITH THE MICROPARTICLE, RESIN COMPOSITION AND OPTICAL FILM |
摘要 |
<p>Microparticles having the content of coarse particles exceeding the average particle diameter reduced to a low level; a process for producing such microparticles; and a resin composition containing the microparticles. The microparticles are characterized in that the content of coarse particles with a diameter of twice or more the average particle diameter is 1000 particles/0.5g or less. The process for producing the microparticles comprises the steps of wet classification of a microparticle dispersion liquid of 0.5 to 50 mass% solid content and 0.5 to 20 mass B-viscosity; drying and pulverization of the microparticles after the wet classification to thereby obtain powdery microparticles of 0.05 to 2 mass% water content; and dry classification of the powdery microparticles.</p> |
