As early as the 1960s, people began the research and application of water-based inks. Due to environmental protection requirements and the shortage of petroleum raw materials, some developed countries have gradually restricted the use of petroleum products to make printing inks. As a result, people began to study non-organic solvent-based inks, which enabled water-based inks to achieve greater progress and development. Initially, water-based inks mainly used dextrin, shellac, casein, sodium lignin and other substances as continuous materials for water-based inks, and the prepared water-based inks were mainly used for the printing of some low-end products. By the end of the 1960s, with the development of material science, the synthetic technology of rosin and maleic acid modified resin was successful, replacing shellac, casein, sodium lignin and other materials, becoming the main materials for water-based inks. Meet the printing needs at that time. However, these primary products still have some drawbacks, such as poor gloss, poor water resistance, poor adhesion, easy foaming, and poor storage stability. Later, people called the water-based ink produced at this stage the first-generation product. In the 1970s, due to the oil crisis, ink raw materials were very tight, and developed countries restricted VOC emissions in the atmosphere. Ink R&D personnel from various countries continue to conduct in-depth research and manufacture the second-generation product of solution-based styrene-acrylic copolymer resin as a continuous material. This product makes up for the lack of water resistance and poor storage stability of the first-generation water-based ink, but in terms of glossiness, etc. There is still a big gap with solvent-based inks. To this end, ink developers have introduced acrylic monomers and polymerized with styrene on the basis of the second generation of water-based inks, and developed a polymer emulsion resin with a core-shell structure and a network structure. This series of resins greatly improves the gloss of inks and promotes the development of water-based inks. At present, my country's water-based ink technology has matured a lot compared with before, and it can basically meet the requirements of the downstream printing and dyeing industry.
