CLARIANT Graphtol Red LG
Index number: pigment red 53:1
Chemical structure: mononitroazo pigment
Clariant CLARIANT Graphtol Red LG is an economical, high-temperature resistant, environmentally friendly yellow-red pigment. It features a vibrant color and excellent coloring strength, with good heat stability and acid-alkali resistance. However, its lightfastness is average, making it unsuitable for applications requiring high lightfastness. The environmental compliance of Clariant LG red organic pigment meets the European EN71-3-1994 standard, making it suitable for coloring consumer goods, food packaging, and toys. When another product, Clariant LC red, does not meet the safety regulations for consumer goods, food packaging, and toys due to its Ba barium ion content, Clariant LG red is recommended as an environmentally friendly alternative.
