In Terms Of Characteristics, Organic Pigments Are Different From Dyes And Inorganic Pigments
1、 Organic pigments and dyes:
The difference between organic pigment and dye is that it has no affinity with the object to be colored. Only through adhesive or film-forming material can the organic pigment be attached to the surface of the object or mixed in the interior of the object to make the object colored. The intermediates, production equipment and synthesis process required by the production of organic pigments are similar to those of dyes. Therefore, organic pigments are often produced in the dye industry.
2、 Organic and inorganic pigments:
Compared with ordinary inorganic pigments, organic pigments usually have higher coloring power, particles are easy to grind and disperse, not easy to precipitate, and their colors are more bright, but their properties of light resistance, heat resistance and weather resistance are poor.
Organic pigments are widely used in the coloring of inks, coatings, rubber products, plastic products, stationery and building materials.
3、 Features:Inorganic pigments are light resistant, heat-resistant, weather resistant, solvent resistant and strong covering power, but their chromatograms are not complete, their coloring power is low, their color brightness is poor, and some metal salts and oxides are toxic.
Tension, improve its wetting and dispersing properties.
