China Organic Pigments Suppliers: High-Quality Color Solutions from a Leading Factory for Printing Ink Industry
Product Details
Organic pigments are a class of colored organic compounds that are insoluble in water and the mediums used (such as oils and solvents). They typically exist as highly dispersed microparticles, adhering to the surface of an object or mixed within the object through binders or film-forming substances, thereby coloring the object.

Classification by Chemical Structure
Main Application Areas
Organic pigments, due to their vibrant colors, strong tinting strength, and high safety, have a wide range of applications:
The largest application area, accounting for approximately 60% of organic pigments usage across all printing industries.
Used in automotive paints, architectural coatings, and industrial anti-corrosion coatings for durable color performance.
Used for coloring plastic products, synthetic fiber pulp, and rubber tires with stable, lasting color.
Art pigments (watercolors, oil paints), cosmetics, stationery (crayons, colored pencils), and electronic materials such as LCD color filters.
Core Characteristics of Organic Pigments
Particle size (typically nanometer to micrometer range) directly affects color, tinting strength, hiding power, transparency, and weather resistance. Smaller particles generally yield higher transparency and stronger tinting strength.
Smaller particle size leads to a larger specific surface area and stronger surface adsorption, which affects the pigment's dispersibility and rheological properties in the medium.
The same chemical structure may exist in multiple crystal forms with drastically different colors, stability, and application properties. For example, phthalocyanine blue has α, β, and γ forms — the β form is a stable green-blue.
Pigment particles are usually surface-treated (e.g., surfactants, resin coatings) to improve dispersibility, stability, or impart special functions. Treated pigments are called easily dispersible or pre-dispersible pigments.
Refers to the pigment's ability to resist attack from acids, alkalis, oxidants, and reducing agents. This is crucial for applications such as coatings and plastics used in special or demanding environments.
Organic pigments are a class of colorants with rich colors, adjustable properties, and good environmental friendliness. In practical applications, it is necessary to comprehensively weigh the advantages and disadvantages based on specific needs — such as required brightness, durability, cost, and processing conditions — and pay attention to core characteristics such as particle size and crystal form in order to select the appropriate variety.
