Do you write slogans on the wall with ink or poster color?

Ink used to write slogans on the wall. The ink is evenly mixed and repeatedly rolled to form a viscous colloidal fluid. Compared with advertising paint, ink is more suitable for writing slogans on the wall. It consists of adhesive (resin), pigment, filler, additive and solvent. Used in books and periodicals, packaging and decoration, architectural decoration and electronic circuit board printing. With the increase of social demand, the variety and output of ink also expand and increase accordingly. Pigments include pigments and dyes. Pigments can be divided into organic pigments and inorganic pigments. The former has bright colors, strong coloring power and short drying time, so it is widely used in inks, such as azo pigments and phthalocyanine pigments. The latter has good light resistance, heat resistance, solvent resistance and concealment, such as titanium dioxide, cadmium red, chrome green, ultramarine and so on. Pigment is colored in granular state and insoluble in water. It is the most commonly used pigment in ink. However, when dyes are used, the effect is not as good as that of pigments when they are prepared into solutions and colored in molecular state. Pigments can give ink different colors and color concentrations, so that ink has a certain viscosity and dryness.
