Dyes are intensely colored or fluorescent organic substances only, which impart color to a substrate by selective absorption of light. They are soluble and 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. A. S. Paterson Company Limited have been working since 1928 to provide excellent colour pigment products and dyes in the market.
The Mechanism of Colour Pigment
Colour Pigments usually dispersed in vehicles or substrates application. For instance, in the manufacture or inks, paints, plastics or other polymeric materials. Pigments retain a crystal or particulate structure throughout the coloration process. They change appearance by selective absorption and by scattering of light. Colour pigments are colored, black, white or fluorescent particulate organic or inorganic solids which commonly insoluble. It is essentially physically and chemically unaffected by vehicle or substrate.
The usage of colour pigment comes in various applications. Some of it is for printing inks, paints, masterbatches, plastics, PVCs, detergent, and rubber. Different approaches needed in each procedure. Dye and paint companies usually work on the materials to fit for specific applications. There are classifications of colour pigment that you may choose. The importance is you familiarize yourself with its properties.
Pigments that contribute light-scattering properties to coatings are generally known as white or hiding, pigments. They act by scattering all wavelengths of light, owing to their relatively high refractive index, so that they are perceived as white by the human eye. They are known as hiding pigments because the scattering of light reduces the probability that light will penetrate through a pigmented film to the substrate. The white colour pigment is used in very high volume worldwide, especially in the so-called trade sales market, which includes retail, architectural, and contractor markets.
