Organic dyes have advantages

Organic dyes have advantages

Organic pigments are also divided into natural and synthetic two categories. Now commonly used is synthetic organic pigments, can be divided into monoazo, bisazo, lakes, phthalocyanine and fused ring pigments and other categories. The advantages of organic pigments are high tinting strength, bright color, complete chromatography and low toxicity. The disadvantage is that the light resistance, heat resistance, weather resistance, solvent resistance and hiding power of the product are not as good as inorganic pigments.

Use and scope of organic dyes

Use and scope of organic dyes

Organic pigments are mainly used for coloring leather paint, high-grade plastic resin, paint printing and synthetic fiber of soft plastic products. Heat resistance 300-450, light resistance 8, migration resistance 5, pure and full color, strong coloring power, good color fastness, excellent solvent resistance, excellent thermal stability, 300 and high temperature resistance, excellent weather resistance, high light fastness, good dispersion, easy modulation and convenient use, as a color matching pigment can adjust a variety of colors, safety and environmental protection.

Development Pattern and Future Trend Analysis of Organic Pigment Industry

Development Pattern and Future Trend Analysis of Organic Pigment Industry

The characteristics of machine pigments (1) pigments and dyes make substances appear color substances are collectively referred to as colorants, colorants are mainly divided into dyes and pigments. Dyes refer to colorants that are soluble in water or other solvents; pigments are colorants that are insoluble in water or other solvents, and are mainly colored by fine particles dispersed in the use medium. In addition to light resistance, weather resistance, acid and alkali resistance, solvent resistance, migration resistance and other characteristics similar to dyes, pigments also have other specific properties, such as color, tinting power, dispersion, hiding power, heat resistance, water permeability, warping resistance and so on. Categories of products included in colorants
