Both major colorant sources are the pigments and dyes. However, there is some difference in the attributes, manner of use, benefits and the sore points of all them however quite often the conditions, pigment, dye, colorant, dyestuff, paint, color are incorrectly used interchangeably.
Colorants come from inorganic and organic dyes and sources constitute a large proportion of the organic colorants whereas the pigments come mostly from the organic sources. Naturally sourced pigments are obtained from fruits, animals and minerals resources; however, majorly pigments comprise of inorganic oxides and additives such as iron and chromium oxides which get diffused in powder form in the medium of use. The dyes are divided into natural dyes and artificial whereas the organic sources of dyes are just like those of pigments while artificial dyes are oil compound based.
Dyes and pigments both are equally important to people for supplying colour to all sort of items but the significant 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 since they’re insoluble in either kind of the liquid medium. Additional compounds are needed for attaching the pigment particles into the substrate. By way of instance, pigments for paint require inclusion of polymer in paint for diffusion.
The vibrancy of color of the dyes depends on its chromophore molecule’s electronic properties. Colorants from dyes impart greater brilliance and show greater color strength besides being easier to process. One of the dyes, basic dyes are more famous for their vibrancy and brightness and compatibility with anionic and synthetic substances.
However, their cons include low color strength and brilliance. As a result of starkly different features of dyes and pigments many attempts were made to boost the properties of each colorant class. This caused the development of a new colorant class called since the Nanocolorants.
This class strives to unite the fantastic processability and superior chromatic characteristics of dyestuffs and better durability of natural pigments. Combining the benefits of the colorants, Nanocolorants have emerged a much better alternative, and it has demonstrated superior features demonstrating tremendously beneficial in a number of applications like preparing aqueous ink-jet inks, high-performance color resistant polymer coloration, electro-photographic toners amongst others.
Whatever the case, notwithstanding the features, pigments and dyes are crucial elements for assisting us to direct a color filled lifestyle.
