PY 108 – Anthrapyrimidine Yellow is a synthetic organic pigment belonging to the anthrapyrimidine family, a group of high-performance yellow pigments known for their bright, warm hues, chemical stability, and excellent lightfastness. PY 108 is characterized by a clear, slightly reddish yellow with strong chromatic purity, making it a versatile choice in both artistic and industrial applications.

Chemically, PY 108 is based on a fused aromatic heterocyclic anthrapyrimidine structure. This molecular configuration provides outstanding resistance to light, heat, and chemical agents, ensuring stability in a variety of media. Its robustness allows use in demanding industrial applications such as automotive coatings, plastics, inks, and high-quality paints, as well as in fine art materials where long-term permanence is required.

In artistic applications, Anthrapyrimidine Yellow exhibits high tinting strength and semi-opaque to transparent behavior depending on particle size and formulation. It mixes cleanly with other yellows, reds, and whites to produce a range of warm tones, from golden oranges to soft pastels, while maintaining chromatic clarity without dulling or browning over time. Its transparency also allows for glazing and layering techniques in oil, acrylic, and watercolor painting.
