What is a pigment?

Pigments are substances that add a specific color to other materials and are used in various industries, especially in paint, plastic production, cosmetics, food, and printing ink. dyes and Pigments are solid particles that are insoluble in water or oil. These materials are pigments due to their specific chemical structure and give color to various surfaces. Dyes and pigments are produced as very fine powders so that they are well dispersed in other materials. Pigments come in various colors and can be combined to create any desired color.

Pigments are usually dispersed in a liquid or other base material to create the desired color. Due to their ability to absorb and reflect light, these materials have a specific color and transfer this color to the surface or material to which they are added. Pigments allow us to see different colors and visual properties.

Types of Pigments

Pigments are chemical substances used as colorants in various industries. These substances have attracted attention due to their special capabilities in coloring, protecting, and creating aesthetic properties.

Pigments are water-insoluble coloring substances that are divided into two main categories based on their chemical composition and structure: inorganic and organic. Inorganic pigments, which are dyes, are usually obtained from plant or mineral sources, while organic pigments are prepared through chemical processes.

Pigments are usually used as tiny particles (nanoparticles) in various systems such as paints and inks. These particles can absorb or reflect light, which helps produce different colors.

Organic pigments

These pigments are produced synthetically and chemically in laboratories and factories. These pigments are often obtained from the polymerization of various chemical compounds. Features such as light resistance and color stability are among the characteristic features of these pigments. Organic pigments have a wide range of colors, high stability, and are more expensive than natural pigments and for this reason, they are used more often.

Organic pigments can be divided into different groups based on their chemical structure, including:

  • Azo: This group is the largest and most widely used category of organic pigments. They contain one or more azo groups (-N=N-) and cover a wide range of colors, from yellow to red and blue.
  • Phthalocyanine: These pigments are known for their brilliant blue and green colors, excellent light and heat stability, and high tinting strength. Copper phthalocyanine is the most common pigment in this group.
  • Polycyclic: This group includes pigments with a multi-ring structure such as anthraquinone, perylene, and quinacridone. They offer a variety of colors including red, orange, purple, and reddish-brown.
  • Diketopyrrolopyrrole (DPP): These pigments are known for their brilliant red and orange colors, excellent light and heat stability, and high tinting strength.

Inorganic Pigments

These pigments are inorganic or organic color compounds obtained from mineral sources and layers of the earth. These pigments are usually composed of oxides, sulfides, sulfates, silicates, carbonates, and other inorganic compounds. They are widely used in various industries due to their high stability to light, heat, and weathering, good covering power, and relatively low price.

Titanium dioxide (TiO2):

A very important white pigment that is widely used in paints, coatings, plastics, paper, printing inks, and cosmetics due to its excellent covering power, transparency, and high stability to light and weathering. This pigment is used in the production of white masterbatches.

Iron oxide:

A group of pigments with a variety of colors including yellow, red, brown, and black. Used in the production of paints, coatings, building materials, ceramics, and plastics.

Zinc oxide (ZnO):

A white pigment used in paints, coatings, cosmetics, and personal care products for its antibacterial and antifungal properties.

Zinc sulfide (ZnS):

A white pigment often used with titanium dioxide to increase coverage and reduce cost. It is also used in the production of transparent plastics and display screens.

Lead chromates:

A group of yellow, orange, and red pigments. Despite their bright colors, their use has been limited due to the toxicity of lead.

Cadmium:

Cadmium pigments produce bright yellow, orange, and red colors. Despite their attractive colors, their use has been limited due to the toxicity of cadmium.

Aluminosilicates:

Mineral pigments with blue and green colors that are used in ceramics and heat-resistant paints due to their high thermal stability.

Carbon black:

A black pigment obtained from the incomplete combustion of organic materials. Used in printing inks, paints, coatings, plastics, and rubbers. Carbon is the main ingredient in the production of black masterbatch.

Ultramarine:

A blue pigment consisting of sodium aluminosilicate containing sulfur. Used in paints, coatings, plastics, and printing inks.

What is the difference between organic and inorganic pigments?

Organic pigments are made from organic compounds and can be of laboratory or synthetic origin. Their chemical structure is more complex than that of the inorganic type and usually includes benzene rings and carbon chains. Synthetic pigments have a variety of colors, brilliance, gloss, and high transparency. These materials are less resistant to light, heat and chemicals than inorganic pigments.

Inorganic pigments are made from natural minerals found in nature. They have a simpler chemical structure than organic pigments and are usually metal compounds or metal oxides. These types of pigments have a more limited color spectrum and produce darker and more opaque colors than organic materials. High coverage and stability against light, heat, and chemicals distinguish them from organic pigments. Some lead-containing minerals are harmful to humans and the environment. Low price and affordability are another feature of this type of pigment.

Organic pigment Inorganic pigment
Complexity of the structure Simple structure
Wide color spectrum Color spectrum limitation
High transparency and brightness Less transparent and shiny
Less coverage and spreadability High coverage and spreadability
Low stability to light, heat and chemicals High resistance and stability to light, heat and chemicals
High production cost and price Low price
Free of toxic substances and lead (healthy) Some types contain lead.

Pigment Applications

Pigments or dyes are chemicals that add color to various products and applications. They are used in various industries, including paint, agriculture, food, and even medicine.

In choosing the right pigment for each application, factors such as:

  • Stability to light, heat, and chemicals
  • Tinting strength
  • Transparency or opacity
  • Viscosity
  • Compatibility with other materials
  • Safety and environmental regulations are considered.

When choosing between organic and inorganic pigments, paying close attention to their application is important. For example, if you are designing an art piece that requires vibrant, glossy colors, organic pigments may be a better choice. However, if you want to choose a color that can withstand weather conditions, such as those used on building facades, inorganic pigments will be the best option.
