The ink composition

The ink composition of the pigments, binders, fillers, additional materials such as.

(1) Pigment

Plays the role of the color pigment in the ink, it some of the characteristics of the ink has a direct impact.

The pigment is not soluble in water and organic solvents, colored, black or white high dispersion of the powder, according to its source and chemical composition, divided into two major categories of organic pigments and inorganic pigments.

① inorganic pigments are non-ferrous metal oxides, or metal insoluble metal salts, inorganic pigments are divided into natural inorganic pigments and synthetic inorganic pigments, inorganic pigments natural mineral pigments.

The ② organic pigment is a colored organic compounds, and is also divided into two major categories of natural and synthetic. Now commonly used in variety of synthetic organic pigments, organic pigments, the color is relatively complete, and better performance than inorganic pigments.

The dyes are organic compounds, soluble in water, sometimes dissolved in organic solvents, insoluble color precipitate from some kind of dye can be prepared, called lake pigments for the manufacture of printing inks.

Requirements of high pigment used in printing inks, especially color, dispersion, light offerings, the transparency requirements of the hue of the color pigments close to the spectral color, saturation should be as large as possible, three primary colors of ink used in magenta, green, The yellow pigment transparency must all pigments not only to water resistance, but also to quickly and evenly and connecting material combined with the oil absorption capacity of the pigment should not be too large, the pigment preferably with alkali, acid resistance, alcohol resistance potential such as performance.

(2) connection material

The binders are the major components of the ink, plays a dispersed pigment, to give ink to the right of the stick, mobility and transfer performance, and printing through
