Pigment ink materials: including pigments and dyes, pigment organic and inorganic pigments, the former bright colors, strong coloring, put the dry time is short plating ink manufacturers, so a wider application in ink, azo, phthalocyanine green lines such as pigments; the latter light resistance, heat resistance, solvent resistance, hiding power are good, such as titanium dioxide, cadmium red, chrome green, ultramarine blue and the like. A coloring pigment in particulate form, but does not dissolve, is the most commonly used ink toner. And when using dye inks formulated as a solution, showing molecular coloring, as effective as pigments. Colorant to give a different color of ink and the ink color density of PP wholesalers, and the ink has a certain viscosity and drying property. Pigment ink material on oxidatively drying resistance of the ink in the case where the polymerization reaction is a pigment and fillers and other solid dispersed phase carried out. Different pigments to oxidative polymerization of different reactive ink. Some pigments are inert, no significant effect on the drying properties of the ink. Some pigments drier effect, their mechanism of desiccant driers are similar, but drier capability is much weaker. Most organic pigment inks of oxidative polymerization drying has hindered, particularly pigment molecular structure containing phenol, phenol, naphthol, amine, aniline, etc. groups, can inhibit the oxidative polymerization of binders. Therefore, the use of these pigments formulated oxidative drying ink conjunctiva. Slow drying. Common barriers oxidative drying ink pigments also black, titanium dioxide, tungsten, molybdenum and phosphorus azo red pigment salt precipitation. The proportion of the ink and paint application is also related to the strength of the dispersion of ink penetration and penetration drying speed. A large proportion of the amount of pigment particles fine, uniform dispersion binders when penetration impediment to large, and the capillary action of the pigment particles formed by the strong, so the penetration binders diminished capacity, the corresponding ink drying is also decreased.
