AI Technical Summary
Existing water-based inks are prone to scratches, abrasions, and uneven gloss during the printing process. Their scratch resistance is difficult to balance the brittleness and toughness of the film layer, and the uneven distribution of the slip component makes the surface susceptible to mechanical friction damage.
A multilayer core-shell grafted hybrid emulsion is used as the film-forming resin, including a polyurethane core layer, an acrylic intermediate layer containing diacetone acrylamide, and an acrylic outer layer containing reactive organosilicon macromonomers. It is combined with an oxazoline copolymer solution and a diacylhydrazine crosslinking system to form a covalent grafted structure and crosslinking network, thereby improving the film density and slip characteristics.
This technology enables water-based inks to maintain good toughness while improving surface slip characteristics and scratch resistance, reducing the probability of scratch formation, and enhancing the scratch resistance of the film.
