What is Pigment Yellow 12

Pigment Yellow 12 (C.I. 21090) is a synthetic organic diarylide yellow pigment widely used in printing inks and general industrial coloration. Based on diarylide azo chemistry, it provides a medium to greenish-yellow shade with relatively high tinting strength and good flow characteristics in ink systems. Pigment Yellow 12 is commonly selected for publication printing and packaging applications where balanced performance and cost efficiency are required.

Key Performance Properties Related to Applications

Color Shade
Pigment Yellow 12 provides a medium to greenish-yellow tone, frequently used as a standard process yellow component in printing ink formulations.
Tinting Strength
It offers relatively high tinting strength among diarylide yellows, enabling efficient color development in ink systems.
Flow and Rheology Behavior
The pigment supports stable flow properties in offset and gravure inks, contributing to consistent printability.
Dispersibility
Can be dispersed using conventional milling methods in common ink and coating binders.
Heat Resistance
Suitable for low to moderate temperature applications; not typically recommended for high-temperature engineering plastics.

Advantages

1. High Color Strength and Transparency

Pigment Yellow 12 offers excellent color strength and transparency, making it ideal for vibrant and bright applications in printing inks and coatings.

2. Excellent Heat Resistance

This pigment exhibits outstanding heat resistance, making it suitable for applications requiring high thermal stability, such as coloring polyurethane foam.

Typical Limitations

Moderate lightfastness compared to high-performance yellow pigments
Limited resistance to prolonged outdoor weathering
Not suitable for high-heat plastic processing
Possible migration in certain plasticized systems

Buyer Guidance

When selecting Pigment Yellow 12, buyers typically consider:

Printing process type (offset, gravure, flexo)
