1.Product Description
Pigment Orange 34 (P.O. 34) is an innovative high-performance naphthol-based organic pigment, redefining bright orange coloration for modern industrial applications with its unique vivid hue and subtle red undertones—distinct from dull, flat orange pigments on the market. Unlike ordinary orange pigments that lack saturation, fade easily, or suffer from poor dispersion, our P.O. 34 features a proprietary crystal refinement process, delivering three client-centric advantages: a stunning bright red-undertone orange hue, exceptional tinting power, and seamless dispersion—solving manufacturers’ pain points of color inconsistency, low aesthetic value, and high production waste.
Crafted with advanced low-temperature azo coupling technology, Pigment Orange 34 boasts a uniform needle-shaped particle structure (0.15–0.20 μm) and optimized specific surface area (20–24 m²/g), ensuring seamless integration into solvent-based, aqueous, and plastic melt formulations, even in high-speed processing. Its distinct red undertone sets it apart from conventional orange pigments, offering a warm, vibrant color that elevates product aesthetics, while its optimized particle size reduces loading requirement by 16% compared to standard P.O. 34 variants—directly cutting raw material costs. Additionally, it is 100% compliant with REACH, RoHS standards and EINECS 239-898-6, non-toxic, heavy metal-free, and suitable for diverse high-end applications.
Engineered for long-term reliability, Pigment Orange 34 boasts Grade 6 lightfastness and thermal stability up to 190°C (10min tolerance) and 170°C (30min tolerance), retaining its vivid bright orange hue even after prolonged UV exposure and high-temperature processing. Its excellent solvent stability (resistant to alcohols, esters, and xylene) prevents color bleeding and migration, ensuring consistent color in end products. With broad compatibility and high tinting strength, it is a versatile one-stop solution for diverse industries, delivering consistent, eye-catching results that set your products apart—combining innovation, stability, and cost-efficiency in one high-performance bright orange pigment.

3.Product Application
Pigment Orange 34 is a versatile, high-value organic pigment, tailored to meet the specific needs of diverse industries with its unique bright red-undertone orange hue, high saturation, and exceptional stability. Below is its detailed application by industry, each section focused on client benefits and practical use cases:
3.1 Printing Inks
Pigment Orange 34 is a top choice for high-end solvent-based and aqueous printing inks, including offset, gravure, digital, and flexographic printing inks. Its excellent dispersion capability eliminates color bleeding and sedimentation, ensuring smooth ink flow even in high-speed printing. With high tinting strength, only 14% loading is needed to achieve standard color depth, significantly reducing ink formulation costs. The bright red-undertone orange hue delivers sharp, vibrant prints with excellent clarity, making it ideal for luxury packaging, brand logos, promotional materials, and food packaging labels, while its good lightfastness ensures long-lasting vibrancy under various conditions.
3.2 Automotive & Industrial Coatings
Perfect for automotive basecoats, touch-up paints, architectural coatings, and metal coatings, Pigment Orange 34 offers excellent compatibility with solvent-based and water-based coating systems. Its good flowability and color saturation allow for increased pigment concentration to enhance coverage without affecting gloss, making it ideal for automotive and industrial finishing. The bright red-undertone orange adds a bold, energetic aesthetic to coatings, while its thermal stability and chemical resistance prevent fading, chalking, and corrosion—ensuring long-lasting color retention in harsh outdoor and industrial environments.
3.3 Plastics
Suitable for engineering plastics (PP, PE, PVC, ABS), Pigment Orange 34 features excellent compatibility and low migration. Its uniform needle-shaped particle size ensures uniform color distribution during injection molding and extrusion, eliminating streaking or color unevenness. It performs well in both rigid and non-light-colored soft PVC coloring, avoiding color bleeding in most applications. Its high solvent stability prevents color migration in plastic processing, ensuring consistent color in end products like plastic parts, toys, decorative accessories, and packaging, while its low loading reduces formulation costs.
3.4 Textiles & Decorative Colorants
Applicable to water-based and solvent-based textile printing pastes for cotton, polyester, and blended fabrics, Pigment Orange 34 delivers excellent wash fastness and rub fastness, retaining its bright red-undertone orange hue even after repeated laundering. It is also suitable for decorative colorants (ceramic glazes, candle wax, and wall paints) and high-end art supplies, offering a blendable, vibrant tone that appeals to professional artists and hobbyists. Its eco-friendly formulation and good compatibility make it a reliable choice for diverse decorative and textile applications.
