Pigment Yellow 14

Permanent Yellow 2GS (C.I. Pigment Yellow 14) is a green shade yellow pigment with bright color, and it is much greener than benzidine yellow. The coloring strength of Pigment Yellow 14 is lower than Pigment Yellow 13, and its light fastness is 1-2 grades. But it has excellent tingting strength and fluidity in ink and good migration resistance in plastics. Pigment Yellow 14 is an economical type for ink and plastic application. The rocessing temperature of Pigment Yellow 14 should be less than 180℃. And the applications of PY14 in plastics are not same in different regions. In China, Japan, and the United States, the application in polyolefins is more typical than other countries.
