Pigment yellow 155

Pigment Yellow 155 (CAS 68516-73-4), also marketed as Monolite Yellow 4G, is a high-performance azo pigment delivering a clean, greenish-yellow shade with strong lightfastness and heat stability.

It is used across industrial colorant applications where durability and color consistency under processing conditions are critical buying criteria. In coatings and industrial paints, it provides reliable color retention.

This pigment is ideal for exterior and high-bake formulations where UV exposure and elevated temperatures are factors. Plastics processors use it to achieve uniform dispersion in polyolefins and PVC.

It is also suitable for engineering polymers during high-temperature compounding. Printing inks for packaging, including offset, gravure, and flexographic systems, rely on it for sharp, reproducible yellow tones.

The material offers good rub and chemical resistance for demanding print jobs. Textile and paper colorant applications also draw on this pigment where a bright, stable yellow is needed in surface coatings.

It is frequently utilized in specialty finishes requiring high performance. Pigment Yellow 155 is supplied as a dry powder, with press cake forms available from some producers for wet-process applications.

Standard commercial grades are offered at varying pigment strengths and particle size distributions to suit different dispersion requirements. Technical-grade supply is the norm for most industrial users.

Specifications are typically aligned to industry color index standards to ensure consistency. This ensures that the pigment meets the rigorous demands of modern manufacturing and color matching protocols.
