Organic pigments: Production route
Commodity azos versus the luxury tier of high-performance colours
What this tab covers How it is made: the main production routes or, for product families, the main product types and technologies, compared on share of supply, inputs per tonne, plant scale, yield, co-products and unit cost.Organic pigments fall into a commodity tier (azo and phthalocyanine pigments made at scale, largely in China and India) and a specialty tier (high-performance pigments with complex syntheses and tight particle control, long dominated by European and Japanese makers). Synthesis is batch chemistry similar to dyes, but finishing, the control of crystal form and particle size, decides value. Many products need dedicated intermediates (arylides, dichlorobenzidine, phthalic anhydride), and effluent and heavy-metal control are major costs.
Routes compared
| Route | Share of supply | Inputs per tonne | Typical scale | Yield | Co-products | Unit cost |
|---|---|---|---|---|---|---|
| Azo pigments (monoazo, disazo/diarylide yellows and oranges, naphthol and lake reds) | largest group by volume (indicative) | aromatic amine, coupling component (arylide), sodium nitrite, acid (indicative) | 1-20 kt/yr multi-product plants | about 90-95% on amine (indicative) | salty, acidic wastewater; trace PCB formation in some dichlorobenzidine pigments (indicative) | commodity grades priced by Chinese suppliers; intermediates protected by Indian ADD |
| Phthalocyanine pigments (CPC blue 15 series, green 7 and 36) | a large share of volume; India's Meghmani is among the top three in pigment blue | about 1.2-1.4 t phthalic anhydride, about 2-3 t urea and about 0.2 t cuprous chloride per t crude (indicative) | 5-40 kt/yr | about 85-90% (indicative) | ammonia, CO2, copper-bearing effluent | phthalic anhydride and copper set cost (indicative) |
| High-performance pigments (quinacridone, DPP, perylene, benzimidazolone, isoindolinone, dioxazine) | small by tonnage, high by value; China imports more than 50% of high-end grades | not published; solvent-intensive | Lily Group 3 kt/yr quinacridone and 1 kt/yr DPP; China isoindolinone capacity under 5 kt/yr | not published | spent solvents, organic effluent | prices RMB 250,000-550,000/t (DPP 300-500k, quinacridone 350-550k, benzimidazolone 250-450k) |
| Effect pigments (mica-based pearl and metallic effects) | Sudarshan about 15 kt effect capacity plus about 25 kt via Heubach (Arihant) | mica, titanium and iron salts (indicative) | 5-25 kt/yr | not published | acidic effluent | not published |
How each route works
Azo pigments (monoazo, disazo/diarylide yellows and oranges, naphthol and lake reds)Aromatic amines are diazotised and coupled with arylides, naphthols or pyrazolones in water; the precipitate is filtered, washed and dried. Diarylide yellows use dichlorobenzidine.
cheap, bright yellows and reds; weaker light and heat fastness than high-performance pigments
DGTR arylides finding (Oct 2026); indicative Phthalocyanine pigments (CPC blue 15 series, green 7 and 36)Phthalic anhydride, urea and cuprous chloride react at about 200 C to crude copper phthalocyanine, which is conditioned to alpha or beta blue; chlorination gives green 7.
very stable, cheap blues and greens; copper and chlorinated-effluent issues
CRISIL rating rationale, Meghmani Organics (Apr 2026); stoichiometry indicative High-performance pigments (quinacridone, DPP, perylene, benzimidazolone, isoindolinone, dioxazine)Multi-step syntheses with solvents and high-temperature cyclisation, followed by careful particle engineering. Used in automotive coatings, engineering plastics and high-end inks.
outstanding fastness and margins; small markets and long customer approvals
Faxian Gongchang 2026 Effect pigments (mica-based pearl and metallic effects)Mica or synthetic substrates coated with TiO2 or iron oxide layers give pearl and colour-shift effects; often grouped with specialty pigments.
high value in cosmetics and car paint; mica supply chains carry child-labour risk
Arihant Capital; India ADD on Chinese mica-based pearl pigments (extended to 25 Feb 2027) Unit economics are indicative ranges from the sources named; costs move with feedstock and energy prices, plant size and region.
