What is Pigments || Difference Between Dyes and Pigments

Pigments

Pigments are a special type of dyeing or printing material for wet processing technology. It is not so easy task to print or dye material with pigments, because the pigment is 100% water-insoluble. So it needs to take special techniques for pigment dyeing or printing. Generally, pigment is used for printing.

Pigments can be defined as a water-insoluble coloring material mostly of mineral origin that has been used for the coloration of metal, wood, stone, and textile materials. Pigments have different types of chemical characteristics. Some examples of pigments are as follow:

  1. Dioxazine
  2. Fluorubine
  3. Isoindoline
  4. Perylene perinone
  5. Pyrocoline
  6. Quinacridone
  7. ETC

Difference Between Dyes and Pigments

Dyes and pigments are the main coloring materials. So we have to know about the differences between dyes and pigments, which will give us a clear idea about these two. The following are the difference between dyes and pigments. They are-

DyesPigments

  2. The topic was adequately addressed but not thoroughly. This article is in desperate need of editing. Several sentences make no sense. All-in-all I was not very impressed.
