Pigment yellow 155

Pigment Yellow 155 (CAS 68516-73-4) is a synthetic organic azo pigment classified under C.I. 200310, with no assigned E-code. It is commercially available under trade names including Novoperm Yellow 4G, Sandorin Yellow 4G, Monolite Yellow 4G, and Yellow 4GD. It belongs to the disazo condensation pigment class.

In coatings and printing inks, Pigment Yellow 155 delivers strong colour strength and resistance to overcoating solvents, making it suitable for high-quality packaging gravure and offset applications. In plastics, it provides heat stability during processing, allowing use in polyolefin and engineering polymer systems where thermal exposure is a formulation constraint.

Pigment Yellow 155 is supplied as a dry powder in standard industrial packaging and is subject to REACH registration requirements within the European Economic Area. Suppliers typically offer grades optimised for either ink or plastics applications. Procurement teams should confirm grade specification and SDS documentation prior to sourcing.
