| Use | There are 15 types of this product. Under the same color force with C.I. Pigment Yellow 1 has low solubility in fat and aromatic hydrocarbon solvents, good crystallinity, better light resistance and durability, and can give a more transparent ink. I. Pigment yellow 74 slightly strong red light, the same particle size under the color intensity of 1 times. Mainly used for latex paint, paper coloring, water-based dispersion applications, with good alkali resistance. |
