1.Product Description
Pigment Yellow 17 is an innovative high-performance diarylide organic pigment that redefines the standard of luminous gold-shaded yellow for modern industrial applications. Unlike traditional yellow pigments that compromise vibrancy for stability or vice versa, our P.Y. 17 features a proprietary 2,2'-dichlorobiphenyl-bridged diarylide core, combining three game-changing advantages that attract manufacturers worldwide: a unique warm gold undertone (distinct from P.Y.14’s red shade and P.Y.13’s green shade), instant dispersion capability, and 20% lower loading requirement—directly cutting raw material costs while boosting product competitiveness.
Crafted via innovative low-temperature azo coupling and crystal modification technology, it boasts ultra-fine particle size (0.08–0.14 μm) that ensures seamless integration into solvent-based, aqueous, and plastic melt formulations—eliminating clumping, color unevenness, and production waste. Its 100% compliance with REACH, RoHS, and FDA standards (safe for food-contact packaging and cosmetics) adds an extra layer of value, making it suitable for high-end and consumer-facing products.
With Grade 6–7 lightfastness and thermal stability up to 220°C (short-term processing), it retains its vivid gold hue even under UV exposure and high-temperature processing (injection molding, coating curing). What truly sets it apart is its versatility: it performs flawlessly in printing inks, coatings, plastics, and decorative colorants, delivering consistent, long-lasting results that help your products stand out in a crowded market. It’s not just a pigment—it’s a cost-effective, safety-compliant solution to elevate your product aesthetics.

3.Product Application
Pigment Yellow 17 is a versatile, high-value organic pigment that combines luminous gold shade, instant dispersion, and global compliance, tailored for diverse industrial applications. Below is its detailed application by industry, with each section concise and focused on client-centric benefits:
3.1 Printing Inks
Ideal for high-end solvent-based and aqueous printing inks, including offset, gravure, and digital inks. Its ultra-fine particle size and instant dispersion capability ensure seamless integration into ink formulations, eliminating clumping and color unevenness even in high-speed printing. With 20% lower loading than conventional variants, it cuts raw material costs while delivering sharp, fade-resistant prints (Grade 6–7 lightfastness). FDA-compliant, it is safe for food packaging labels, where its warm gold undertone enhances shelf appeal, making printed products stand out in crowded markets. It also blends well with other pigments to create custom warm tones, suitable for luxury packaging, retail signage, and decorative printing.
3.2 Automotive & Industrial Coatings
Perfect for automotive basecoats and industrial coatings (architectural, metal, machinery). It delivers a premium gold finish with strong weather resistance, retaining vibrancy for over 8 years of outdoor exposure without fading or chalking. Compatible with both solvent-based and water-based coating systems, it creates a smooth, flawless surface with no visible pigment particles. Its compatibility with metallic additives allows for multi-dimensional luxury finishes, ideal for high-end vehicles. Thermal stability up to 220°C ensures consistent performance during coating curing, eliminating color shift and ensuring batch-to-batch consistency.
3.3 Plastics & Food-Contact Packaging
Suitable for engineering plastics (PP, PE, PVC, ABS) and food-contact packaging. With ≥99% purity and FDA/REACH compliance, it is non-toxic and low-migration, safe for food containers, plastic toys, and consumer goods. Its instant dispersion ensures uniform color distribution during injection molding and extrusion, eliminating streaking and surface defects. The 20% lower loading requirement reduces plastic formulation costs, while its thermal stability prevents color fading during high-temperature processing. Its warm gold hue enhances product appeal, making it a cost-effective choice for high-volume plastic production.
3.4 Textiles & Decorative Colorants
Applicable to textile printing pastes (water-based and solvent-based) for cotton, polyester, and blended fabrics, delivering wash-fast gold hues that retain vibrancy after 50+ washes. It is also suitable for high-end art supplies (acrylics, colored pencils) and EU-approved cosmetics (lipsticks, blushes), offering a smooth, blendable texture and luminous gold tone. For decorative colorants (ceramic glazes, candle wax), it withstands high temperatures and long-term use, ensuring consistent color and elevating the aesthetic value of decorative products.
