Should I use ink or advertising paint to write slogans on the wall?

Use ink to write slogans on the wall. The ink is evenly mixed and rolled repeatedly to form a viscous colloidal fluid. Compared with advertising paint, ink is more suitable for writing slogans on walls. It consists of binder (resin), pigments, fillers, additives and solvents. Used for various printing of books, periodicals, packaging and decoration, architectural decoration and electronic circuit boards. As social demand increases, ink varieties and output have also expanded and grown accordingly. Colorants include pigments and dyes. Pigments are divided into organic pigments and inorganic pigments. The former has bright colors, strong tinting power and short drying time, so it is widely used in inks, such as azo and phthalocyanine pigments. The latter has better light resistance, heat resistance, solvent resistance and hiding power, such as titanium white, cadmium red, chrome green, ultramarine blue, etc. Pigments are colored in particulate form and do not dissolve. They are the most commonly used colorants in inks. When dyes are used, they are prepared into solutions and are colored in a molecular state, so the effect is not as good as pigments. Colorants can give the ink different colors and color concentrations, and make the ink have a certain viscosity and dryness.
