摘要： Method for recycling printed plastic articles without contaminating or staining the recycled plastic with color due the printed ink. The ink is a water-based composition comprising select self-crosslinking acrylate copolymers or polyurethane resins, which inks exhibit good adhesion under conditions of use, but which are readily removed as solid particles when exposed to a hot caustic solution. Due to the inks being removed as solid particles, and not dissolving into the ink, the recycled plastic remains uncontaminated by the ink during recycling.

摘要： The present invention provides a printing ink or coating composition comprising a self-crosslinking acrylic polymer and a silicone emulsion wherein the self-crosslinking acrylic polymer has a minimum film forming temperature of less than 25° C. Furthermore, the present invention also provides a process for preparing a coated substrate, in particular a polyboard substrate, and an article made from the coated substrate, such as a milk or juice carton.

摘要： Described herein are opaque water-based inks that include water and an opacity-providing polymer component. In one aspect, the opacity providing polymer component is a hollow sphere polymer material. The opacity-providing polymer material may replace all or part of white opacifying pigment material, such as titanium dioxide. Also described herein is a method of opacifying a printing ink by adding hollow sphere resin particles and a colorant to a printing ink that comprises water as a volatile component.
