Related Information

There are 36 types of pigment commercial dosage forms, and they still have a certain market in Europe, America and Japan. It gives a yellowish orange color, which is significantly redder than the C.I. pigment orange 13 and pigment orange 34. Mainly used in printing inks, and can be used to adjust the color light of C.I. Pigment Yellow 12. Resinized formulations have high transparency, but poor fluidity. Due to their poor fastness properties, they are mostly used for packaging inks with high transparency and low cost.
