Properties and application of pigment yellow 74

Pigment yellow 74 is an important commercial pigment, which is mainly used in printing ink and coating industry. Its color paste is between pigment yellow 1 and pigment yellow 3, and its coloring power is higher than that of any other mono even nitrogen pigment yellow. Pigment yellow 74 is acid, alkali and saponification resistant, but it is easy to frost, which hinders its application in baking enamel. The light fastness of pigment yellow 74 is 2-3 grades higher than that of Bisazo yellow pigment with similar colouring power, so it can meet the requirements of high light fastness, such as printing ink for packaging. At the same time, pigment yellow 74 is also widely used in latex paint as interior wall and dark exterior wall coloring.
