Pigment Definition & Classification

Posted by Qualitron Chemicals - phthalocyanine pigments manufacturers in india on March 19th, 2019

Pigments are colored, black, white or fluorescent particulate organic or inorganic solids which usually are insoluble in, and essentially physically and chemically unaffected by, the vehicle or substrate in which they are incorporated. They alter appearance by selective absorption and/or by scattering of light. Pigments are usually dispersed in vehicles or substrates for application, as for instance in the manufacture or inks, paints, plastics or other polymeric materials. Pigments retain a crystal or particulate structure throughout the coloration process.-defined by CPMA (The Color Pigments Manufacturers Association, Inc.) phthalocyanine pigments manufacturers in india


Dyes are intensely colored or fluorescent organic substances only, which impart color to a substrate by selective absorption of light. They are soluble and/or go through an application process which, at least temporarily, destroys any crystal structure by absorption, solution, and mechanical retention, or by ionic or covalent chemical bonds.—defined by ETAD (The Ecological and Toxicological Association of Dyes and Organic Pigment Manufacturers). Both are of categories of colorant which definition is a substance used for coloring a material, sometimes also called coloration matter or coloring matter


Difference Between Organic and Inorganic Pigments
Compared with organic pigments, inorganic pigments have lower cost, simple production process and higher yield than organic pigments. also excellent light resistance, heat resistance, and weatherability. Inorganic pigment is suitable for architectural coatings, glass, ceramics, rubber, and plastics coloring.

Key features and characteristics of Organic Pigments

• Very good stability to solvents, light, heat, and weathering
  Good tinctorial strength
  Cost effectiveness
  Consistency and unique shades
  Completely non-toxic
  Very bright, pure, rich colors
  Organic pigments shows good color strength

Compared with inorganic pigments, organic pigments are widely used in the fields of ink, paint, and plastic, due to a wide range of colors, bright colors, and bright hue. a very high tinting power is formed. Organic pigments can be prepared through deep processing to meet different application requirements (such as high tinting strength, high transparency, high mobility, etc.) special commodity formulations, among them, high-performance. Organic pigments are with excellent light resistance, heat resistance, solvent resistance, and other applications performance, in line with the high-grade inks, coatings and plastics areas coloring needs.
