Document Type and Number:
Japanese Patent JP7259231
Kind Code:
B2
Abstract:
To provide particulate silicas, capable of obtaining a resin composition excellent in transparency when mixed with a resin having a refraction index of 1.49 or more.SOLUTION: Particulate silicas, the silicas each having a particulate shape, comprise aluminum, wherein when observed with an optical microscope after dispersed in a refractive index standard solution having a refractive index of ±0.01 as much as that of the particulate silicas, a ratio of the particulate silicas in which opaque particles in the particles are observed is 10 or less per 100 particulate silicas.SELECTED DRAWING: Figure 2
