What is the difference between pigment color pastes and dyes used as surface sizing agents in papermaking?
Release Date:
2023/05/30
Pigment color pastes used in papermaking differ from dyes in that pigment particles are insoluble in water or solvents, unlike dyes, which can chemically bond with paper fibers. Consequently, pigment coloration relies on the use of fixing agents to ensure that the pigment adheres firmly to the paper fibers.
Ink is a viscous, liquid mixture composed of various functional ingredients, which can be applied to substrates in a variety of ways—such as printing, spraying, or scraping—to reproduce designed graphics and text. The formulation of ink is complex: in addition to the basic components—pigments, binders, and solvents—it also includes a range of functional additives that enhance ink performance and improve its printability and overall compatibility with the substrate.
