Totally Dissimilar Colorants

Tie Dye, Groovy, Retro, Vibrant, Vivid
Both important colorant sources are the dyes and pigments. However, there is some difference in the features, manner of use, benefits and the sore points of all them though quite often the terms, pigment, dye, colorant, dyestuff, paint, colour are incorrectly used interchangeably.
Colorants come from inorganic and organic dyes and sources constitute a large percentage of the organic colorants while the pigments come mostly from the organic sources. Naturally sourced pigments are obtained from animals, vegetables and minerals sources; however, majorly pigments comprise of inorganic oxides and salts like chromium and iron oxides that get diffused in powder form in the medium of use. The dyes are divided into natural dyes and synthetic wherein the natural sources of dyes are the same as those of pigments while artificial dyes are petroleum compound based.
Dyes and pigments both are equally important to people for supplying colour to all type of items but the major difference between the two lies in their fundamental manner of imparting colour. In the event of dyes, color is diffused in the molecular level since they are soluble in the organic solvent or water whereas in pigments the color is diffused as particles because they are insoluble in either kind of the liquid medium. Additional compounds are needed for attaching the pigment particles to the substrate. By way of example, pigments for paint require inclusion of polymer in paint for diffusion.
The vibrancy of colour of the dyes depends on its chromophore molecule’s electronic properties. Colorants from dyes impart greater brilliance and show greater color strength besides being simpler to process. Among the dyes, basic dyes are more known for their vibrancy and brightness and compatibility with anionic and synthetic materials. However, dyes as colorants exhibit low durability, solvent and heat stability and high levels of migration and acid red being among them is no different.
On the other hand, pigment colorants are stronger, solvent and heat stable besides being migration and lightfast. However, their cons include low colour strength and brilliance. Due to the starkly different features of dyes and pigments many attempts were made to enhance the properties of each colorant class. This caused the development of a new colorant class called as the Nanocolorants.
This class strives to combine the good processability and superior chromatic characteristics of dyestuffs and better durability of organic pigments. Combining the benefits of the colorants, Nanocolorants have emerged a much better alternative, and it has demonstrated superior features proving highly beneficial in several applications like preparing aqueous ink-jet inks, high-performance color resistant polymer coloration, electro-photographic toners amongst others.
In any case, notwithstanding the features, pigments and dyes are indispensable elements for assisting us to lead a color filled lifestyle.
