Melting point 280 °c. Sun resistance, acid resistance and alkali resistance is good, but poor solvent resistance. |
| Use | The pigment has pure yellow-red color, excellent light fastness, and better light fastness than C.I. Pigment Red 10 is more light resistant; But it is unstable to aromatic hydrocarbon solvents, causing changes in crystal form and reduced coloring strength; It has good stability to soap, paraffin and phthalate esters. It is mainly applied to medium without aromatic hydrocarbons, such as water-based and offset printing inks, and has better light fastness than C.I. Pigment Red 53:1; It can also be used for coloring of coatings and latex paints. It is mainly used for coloring of inks and coatings. |
