The organic pigments are mainly carbon black, azo pigments, phthalocyanine, quinoline ketone, isoindolinone, anthraquinone, thioindigo pigments and various chemical manufacturers powdered colorant, wherein the carbon black is the most common use of black powdered pigment colorants Which high-volume, it has cheap colored prison, dispersion, and advantages of the flowability of the plastic while it is endowed conductivity and UV degradation of good candidates and so filling. Ideal coloring agent can make a lot of requirements, such hope it colorful, coloring force, not easily dispersed evenly in the plastic aggregation, high heat resistance and no effect on the flow of plastic, does not affect the resin and resistance to aging Its other performance, weather Fast and inexpensive, non-toxic and so on. 1, food colorants: food coloring to the primary purpose food additive known as a colorant, also called pigment. 2, by source: food can be divided into natural food colorants and synthetic colorants two categories. 3, according to the structure: synthetic food coloring agents can be divided into azo colorants and non-azo colorants; 4, natural food colorants can be divided into azoles, polyenes, ketones, quinones and polyphenols class. 5, according to the solubility of the colorant points: fat-soluble and water-soluble can be divided.
