Use	The pigment gives a strong green-light yellow color with a hue angle of 97.9(1/3SD) and excellent light and weather fastness. I. Pigment yellow 154 compared to light in the light color fastness decreased significantly; Mainly used in automotive coatings (OEM) and repair paint, and phthalocyanine pigments to make green; High thermal stability in plastic coloring, can be used for hard PVC coloring; In the HDPE temperature 270 ℃(1/3SD); For high-grade printing and dyeing ink, Light 6-7 (1/25SD), heat-resistant printed matter 200 ℃/10min; resistant to paraffin, cream, soap, butyl phthalate, toluene, etc.
