Colorants

Colorants include pigments and dyes. Colorants can give inks different colors and color concentrations, and make the ink have a certain viscosity and dryness. Commonly used are azo and phthalocyanine pigments.

Binders

Binders are made by dissolving a small amount of natural resins, synthetic resins, cellulose, rubber derivatives, etc. in drying oils or solvents. They have a certain fluidity, so that the ink forms a uniform thin layer after printing, and forms a film layer with a certain strength after drying, and protects the pigment, making it difficult to fall off.
