WHITE-BASED PIGMENT, WHITE-BASED INK COMPOSITION, INK SET, AND INK JET RECORDING METHOD |
| 摘要 |
A white-based pigment has an S of at least 0.15. The S is defined by equation (1):;S=K1×(1-K2)×a(K3)2K4(1);where K1, K2, K3, and K4 are a structural factor, a porosity, a particle diameter, and a specific gravity, respectively, and 0<K1, 0<K2<1, 1.5×10−7 (m)≦K3≦1.0×10−5 (m), 2≦K4≦8, and a=1.0×1013 (m−2). |
