RESISTANT PRINTING INK SYSTEM

摘要

A water-based acrylic ink system utilizes acrylic color dispersions produces resistant printing inks films that do not bleed when contacting cleaning and disinfectant chemicals. The resistant printing ink system includes an alkali resistant styrene-acrylic hybrid copolymer and an aqueous acrylic dispersion system supporting the alkali resistant styrene-acrylic hybrid copolymer. An amine dispersant such as morpholine can be added to the styrene-acrylic hybrid copolymer before the dispersion is added.
