High‑performance pigments for modern formulations

A review of pigment classes, market drivers, and functional innovation themes (nano‑pigments, IR‑reflective systems) underpinning durability and fastness requirements.

The review argues that increased durability and regulatory/functional requirements in modern formulations necessitate pigments with high stability, fastness, dispersibility, and low migration beyond conventional commodity pigments.

Durability & fastness

Organic and inorganic HPP classes

Functional pigments (nano/IR‑reflective)

Context and objective

The article frames pigment selection as a primary determinant of long-term appearance and functional retention, emphasizing that modern product requirements extend beyond color and opacity to include durability, chemical/thermal stability, light and weather fastness, dispersibility, low solubility, and reduced color migration. The review’s objective is to outline the classes of HPPs, explain why these materials are increasingly required, and summarize major application sectors and innovation directions.

Market pull and sectoral demand

The review describes increasing demand for HPPs across multiple end-use sectors, attributing growth to performance expectations and regulatory pressure for safer and more sustainable product systems. It characterizes the HPP segment as distinct from commodity pigments due to performance intensity and functional differentiation. The text cites market-report-derived indicators of growth and highlights that demand spans multiple industries rather than a single vertical.

Performance definition of HPPs

Core attributes Durability; high color strength; dispersibility; chemical/heat stability; light/weather fastness

Additional constraints Low solubility; minimized color migration

Core function: Establishes HPPs as pigments defined by persistence and stability under service exposure.

Differentiation from commodity pigments

Commodity baseline Color and opacity primarily

HPP requirement Persistent performance in demanding environments

Core function: Explains why HPPs are treated as premium materials in performance-led formulations.

End-use demand breadth

Sectors emphasized Plastics, inks, textiles, paper coatings, automotive, cosmetics (as listed)

Demand driver Higher functional performance and regulatory expectations

Core function: Positions HPPs as enabling materials across multiple product types.

Emerging processing context: additive manufacturing

Use context Additive manufacturing requiring high-quality effects and material consistency

Implication Pigments may be incorporated into polymer matrices used in printing processes

Core function Identifies additive manufacturing as a route that may increase demand for high-performance pigment systems.

Complex inorganic colored pigments (CICPs)

The review presents CICPs as synthetic crystalline metal oxides whose multi-metal composition yields diverse colors and high stability. These pigments are described as transition‑metal‑containing oxides produced by calcination at elevated temperatures and are framed as particularly suitable where thermal/UV stability and long-term color retention are required. The article notes major commercial groupings, including titanates, aluminates, chromites, and ferrites.

Organic high‑performance pigments and crystal structure effects

Organic HPPs are discussed as offering high color strength and chroma with strong stability profiles, while also exhibiting structural sensitivity: molecular shape and intermolecular forces influence crystal packing, polymorphism, and resulting properties. The article notes that organic pigments typically show defined crystallinity and that close packing is influenced by molecular geometry, which can affect fastness and migration behavior. The review also introduces nano‑pigments as a size‑driven class that can improve transparency and dispersibility, and discusses IR‑reflective/cool pigments for thermal management.

CICPs: synthesis and stability

Material basis Synthetic crystalline multi‑metal oxides

Processing note Calcination at elevated temperature (reported range ~650–1300 °C)

Property emphasis Heat stability and weathering stability; UV discoloration resistance

Core function Provides color systems with robust stability in severe exposure conditions.

Organic HPPs: performance profile

Property emphasis High color strength, bright shades, light/weather fastness, solvent resistance

Constraint noted Formulation must balance solubility and migration tendencies

Core function: Supplies high-chroma colorants with engineered fastness characteristics.

Crystal packing and polymorphism

Structural determinants Molecular shape, intermolecular forces, and polymorphic form

Packing note (as framed) Close packing coefficients reported in the ~0.65–0.8 range for organic pigment crystals

Core function: Links microstructure (packing/polymorph) to macroscopic pigment performance.

Nano‑pigments and IR‑reflective/cool pigments

Nano‑pigment definition used Very small particle size (reported <100 nm)

Functional intent Improved transparency/dispersibility; thermal management via IR reflectance in “cool” pigments

Core function Extends pigments from colorants to functional agents (optical/thermal behavior).

Technical determinants and constraints in HPP selection

The review frames HPP selection around sustained color and appearance under thermal, UV, and weathering stressors, alongside chemical resistance and minimized migration. These constraints collectively separate “high-performance” requirements from baseline pigmentation needs.

Fastness and stability requirements as selection drivers

CICPs are described as crystalline oxides formed via high-temperature calcination (reported ~650–1300 °C), with stability arising from inorganic lattice robustness. The review treats this class as a stability-forward option for demanding exposures.

CICP processing window and structure–property rationale

For organic pigments, the article emphasizes that molecular geometry and packing influence intermolecular binding and polymorphism, which in turn govern fastness, solubility, and migration. Thus, organic pigment selection is treated as microstructure-sensitive.

Organic pigment crystal packing and property variability

Nano‑pigments are framed as enabling improved transparency and dispersion due to small particle size (reported <100 nm), while also potentially altering optical and interfacial behavior relative to micronized pigments.
