1.pigment
Paint is colored by coloring material and the material is usually mixed with inorganic compounds, mainly based; dye is a mordant is used, directly or through the role can be attached to a variety of fibers and other materials, some on colored substances material can be dyed with the compounds, mostly organic based.
Pigments can not color, and dye to color.

Paint is paint a secondary film-forming material, the process of modulation in the decorative wood primer, putty and the wood was colored, often with pigments.

2.dyes
Dye is in a certain medium, fiber or other material to make solid colored compounds. We introduce the only organic dyes and pigments. Ancient dyes from plants and animals. 1856 Perkin invented the first synthetic dye - purple tail, so that organic separation of a new discipline - dye chemical. 1950s. Pattee and Stephen found containing dichloro-s-triazine group of the dye under alkaline conditions and fiber bonding on the hydroxyl, marking dye the fiber coloring process of development from the physical to the chemical process, creating a reactive dyes application period . At present, the dye is not limited to textile dyeing and printing it in paint, plastics, paper, leather, optical communications, food and many other departments can be applied.

Dye according to application performance is divided into the following categories:
1. Direct Dyes
(2) Acid Dyes
3 Disperse
4 reactive dyes
5. Vat dyes
6. Cationic dyes
7. Azoic dyes
8. Polycondensation dye
In addition to oxidation dyes, sulfur dyes, etc.
