1. The role of acrylic resin in UV-curable inks. Due to the unsaturated nature of acrylic resin, it can undergo polymerization under the action of ultraviolet light and is widely used in the manufacture of UV-curable inks. It can also be copolymerized with other substances, such as polyethers, polyurethanes, polyesters, epoxy resins, modified epoxy resins, polycaprolactams, etc., and all these copolymers can be used as resin components for UV-curable inks.

2. The role of acrylic resin in water-based inks. Copolymers of acrylic resin with other substances are used in alkali-soluble water-based inks, and acrylic resin copolymer emulsions are used in water-dispersible water-based inks.

3. The role of acrylic resins in solvent-based inks. Most acrylic resins are soluble in solvents such as aromatic hydrocarbons and esters, and some are also soluble in alcohol solvents. They are mainly used in the production of photogravure inks and flexographic inks. Due to their transparent and colorless characteristics, they are also used to produce varnishes.
