A high-chroma naphthol azo red delivering vibrant, clean red shades with excellent flow properties and strong tinting strength. Widely used in packaging inks, industrial coatings, and stationery applications where vivid, consistent red colour is required at competitive cost.
Pigment Red 112 is a monoazo naphthol red produced by coupling a diazonium salt with a naphthol coupling component. This chemistry delivers high colour purity, good transparency in inks, and strong tinting strength — at a more accessible price point than complex polycyclic red pigments. The trade-off is moderate lightfastness and heat stability compared to perylene or quinacridone reds, making PR 112 best suited to indoor and packaging applications rather than exterior-durable uses.

High-chroma red for solvent-based and waterborne flexographic and gravure inks used in food and consumer packaging. Excellent flow properties minimise press issues and deliver consistent colour across long runs.
Used in decorative and general-purpose industrial coatings where vivid red shades are required for indoor or short-term outdoor applications. Verify lightfastness requirements before specifying for long-term exterior use.
Widely used in ballpoint pen inks, stamp pad inks, and stationery products. The excellent flow properties and colour brightness of PR 112 are particularly valued in these precision ink applications.
Suitable for colouring plastics destined for indoor applications — stationery, toys, housewares — where ISO 7 exterior lightfastness is not required. Verify heat stability for your specific processing temperature.
Presscake form is ideal for solvent-flush pastes and high-quality ink grinding. Aqueous dispersions available for waterborne ink and coating systems. Contact us to specify concentration and vehicle compatibility.
