Generally better light stability of inorganic pigments, organic colorants, phthalocyanine-based, quinacridone-based, dioxazine, isoindolinone ketones and other organic pigment is excellent in light resistance, relative to the inorganic pigment match; ketone, anthraquinone and perylene dyes also have good lightfastness. Migration resistance. Migration colorants are mainly three types, 1) solvent extraction, that water and organic solvents bleeding; 2) Contact the migration fertilizer anti-caking colorants, polluting the adjacent object; 3) surface blooming, mainly due to When the colorant in the thermal processing of the polymer greater solubility, and solubility at room temperature is small, and therefore cause crystallization gradually. Inorganic pigments are generally non-homogeneous dispersion in the polymer, no blooming, and organic pigments in the polymer and other organic matter have different degrees of solubility, more prone to migration. Due to the different kinds of resin, plastic chemical structure during molding process requires a different heating temperature (softening point above), the temperature will directly affect the choice of the fertilizer anti-caking colorant colorant manufacturers to make coloring does not occur at a predetermined temperature distinct color change, different characteristics of the resin structure colorant fertilizer requirements are not the same anti-caking colorants guaranteed Table 1 plastic resin molding temperature and colorants requirements. Also some other resin processing temperature, respectively, fluororesin, 350 ℃; acrylic resin, 180-200 ℃; silicone resin, 180 ℃; phenol resin, 150-160 ℃; epoxy resin, 150 ℃; cellulose plastic 180 ℃ and the like.
