POLYAMIDE POROUS SPHERICAL PARTICLE |
| 摘要 |
<p>Disclosed is a polyamide porous spherical particle which is reduced in luminous reflectance. Specifically disclosed are polyamide porous spherical particles having a number-average particle diameter of 2-30 µm, a BET specific surface area of 100-80,000 m<SUP>2</SUP>/kg, and a ratio of the volume-average particle diameter to the number-average particle diameter of 1.52-2.50.</p> |
