introduction | pigment yellow 14 is a green yellow powder with bright color, strong coloring power, good transparency and good application performance. it is one of the important varieties of biphenylamine organic pigments. It is slightly greener than pigment yellow 12 and greener than European color standards. The tinting strength is lower than C.I. pigment yellow 13 and the light fastness is grade 1-2. Solvent resistance and paraffin resistance are better, especially in the United States. It is widely used for packaging ink. |
application | pigment yellow 14 is mainly used for coloring rubber, plastic and rubber products, and is also suitable for coloring polyurethane synthetic leather, high-grade ink, paint and printing paste. |
