| 1. Transparency of TTO series | |
| ○Ultra-fine TiO2 exhibits higher transparency than pigmental TiO2. (see photo 1, 2) | |
| ○TTO-V series, whose particle size is the finest in TTO products, can achieve superior transparency. (see photo.3) | |
| ○To obtain high transparency, the dispersion condition is important in general. The finer particle size are, the stronger dispersion is required. | |

| 2. Flip-flop effect | |
| The metallic paint containing ultra-fine TiO2 changes its color from gold to blue by varying the viewing angle. The illustration as below shows the viewing color change by the flip-flop effect. | |
