Application

Pigment Yellow 17(CAS 4531-49-1) is a versatile organic pigment with a wide range of applications across industries, leveraging its bright greenish-yellow shade, moderate lightfastness, and heat resistance up to 180–200°C. Below is a detailed breakdown of its application versatility:

1. Printing Inks

Packaging & Industrial Inks: Widely used in nitrocellulose, polyamide, and polyethylene/vinyl acetate copolymer-based inks for packaging materials due to its excellent transparency and lightfastness (4–5).
Metal Deco Inks: Exhibits reliable heat stability, making it suitable for metal decoration printing where high-temperature resistance is required.
Color Adjustment: Often blended with Pigment Yellow 83 to create intermediate shades with enhanced lightfastness and transparency, ideal for achieving specific color targets in flexographic or gravure printing.

2. Plastics & Polymers

Thermoplastics:
- Polyolefins: Used for coloring polyethylene and polypropylene at processing temperatures of 220–240°C, with good dispersibility in masterbatch formulations.
- PVC: Suitable for rigid and plasticized PVC applications (e.g., films, cables), where its electrical properties meet industry standards. However, caution is advised in plasticized PVC due to potential migration issues.
Engineering Plastics: Limited use in high-temperature plastics (e.g., ABS, PS) due to its moderate heat resistance (180–200°C), though specific grades may be optimized for niche applications.

3. Coatings & Paints

Cans & Packaging Coatings: Primarily used for interior linings of food cans due to its high transparency and compliance with food contact regulations in some regions.
General Industrial Paints: Less common in exterior coatings due to its moderate lightfastness (6–7), but finds use in decorative paints and primers requiring a greenish-yellow hue.

4. Rubber & Elastomers

Rubber Products: Employed in natural and synthetic rubber compounds for coloring tires, seals, and molded parts. Its compatibility with rubber matrices ensures uniform dispersion and color consistency.

5. Textiles & Leather

Textile Printing: Used in UV-curable inkjet formulations for cotton and polyester fabrics, offering good washfastness (4–5) and lightfastness (6–7) when combined with other pigments like Pigment Red 122.
Leather Dyeing: Though not explicitly listed in cosmetic standards, it is occasionally used in leather finishes for vibrant greenish-yellow tones, often in combination with acid dyes.

6. Specialty Applications

Glass Fibers & Composites: Provides vivid coloring in glass-reinforced plastics (GRP) and fiberglass products, resisting discoloration during high-temperature processing.
Art Materials & Stationary supplies:
- Artist Paints: Valued for its transparency and fluorescence in plastic-based paints.
- Stationery: Used in crayons, markers, and colored pencils for its bright, non-toxic properties (when formulated appropriately)

Advantages

Pigment Yellow 17 (CAS 4531-49-1) offers a balanced profile of technical and commercial advantages that position it as a staple in the pigment industry. Below is a structured analysis of its key strengths, supported by technical details and real-world applications:

1. Vibrant Color Properties

Bright Greenish-Yellow Hue: Delivers a vivid, high-tone shade with strong chroma (up to 85% relative to standard) that is ideal for applications requiring eye-catching visibility, such as packaging graphics or signage.
Transparency & Tinting Strength: Exhibits excellent transparency in thin films (e.g., printing inks), allowing for layering effects, while maintaining high tinting strength (≥100% vs. standard) to reduce pigment loading in formulations.

2. Thermal Stability for Industrial Processes

Heat Resistance up to 180–200°C:
- Suitable for thermoplastics like polyethylene (PE) and polypropylene (PP) processed at ≤220°C, preventing color degradation during extrusion or injection molding.
- Enables use in metal deco inks that withstand curing temperatures in can coatings (e.g., 180°C for 30 minutes).

3. Cost-Effective Performance

Lower Production Cost vs. High-End Pigments:
- Priced ~30–40% lower than premium yellows (e.g., Pigment Yellow 155) while maintaining comparable performance in non-critical applications.
- High pigment loading efficiency (1–3% w/w in plastics) reduces material costs without sacrificing color intensity.

4. Compatibility with Diverse Matrices

Broad Material Adaptability:
- Inks: Compatible with nitrocellulose, polyamide, and vinyl resin systems, making it versatile for flexographic, gravure, and offset printing.
- Polymers: Disperses well in both polar (PVC) and non-polar (PE) plastics, minimizing formulation adjustments.
- Coatings: Works in solvent-based (e.g., alkyd resins) and water-based systems (e.g., acrylic emulsions) for industrial paints.
