Color, Nature, Desktop, Abstraction
Both important colorant sources are the pigments and dyes. However, there is some difference in the attributes, manner of use, benefits and the sore points of each of them however quite often the terms, pigment, dye, colorant, dyestuff, paint, color are incorrectly used interchangeably.
Colorants come from organic and inorganic dyes and sources constitute a large proportion of the organic colorants whereas the pigments come mostly from the inorganic sources. Naturally sourced pigments are obtained from animals, vegetables and minerals resources; however, majorly pigments comprise of inorganic oxides and salts like iron and chromium oxides that get diffused in powder form in the medium of use. The coloring properties of the diffusion are determined by the form and size of the pigment particle. The dyes are divided into natural dyes and synthetic whereas the organic sources of dyes are the same as those of pigments while artificial dyes are oil compound based.
Dyes and pigments both are equally important to humans for providing colour to all type of items but the significant difference between the two lies in their fundamental manner of imparting colour. In case of dyes, color is diffused in the molecular level as they are soluble in the organic solvent or water whereas in pigments the color is diffused as particles because they are insoluble in either type of the liquid medium. Additional compounds are required 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 colour of the dyes depends on its chromophore molecule’s electronic properties. Colorants from dyes impart greater brilliance and show greater colour strength besides being easier to process. One of the dyes, basic dyes are more known for their vibrancy and brightness and compatibility with anionic and synthetic substances. All basic dyes manufacturers in India will confirm their suitability for coloring cationic, artificial items such as acrylics.
But their cons include low colour strength and brilliance. Due to the starkly different features of dyes and pigments many attempts were made to boost the properties of each colorant class. This led to the development of a new colorant class called since the Nanocolorants.
This class strives to unite the fantastic processability and superior chromatic features of dyestuffs and better durability of organic pigments. Combining the benefits of both the colorants, Nanocolorants have emerged a better alternative, and it has demonstrated superior features demonstrating highly beneficial in several applications like preparing aqueous ink-jet inks, high-performance colour resistant polymer coloration, electro-photographic toners amongst others.
Whatever the case, notwithstanding the features, dyes and pigments are crucial elements for helping us to lead a color filled life.
