DISPLAY MEDIUM AND COLOR REFLECTIVE INKS

摘要

Reflective color inks are used, such as for signage applications and as an electronic display medium and material. The reflective color inks comprise a core-shell particle that includes a core particle coated with a molecular surface coating. One example of such a particle is using a core of a polystyrene type of material that has a relatively low refractive index, with a high reflective index acrylic copolymer added as the shell material.

主权项

1. A composition comprising a reflective color ink deposited on a substrate, the reflective color ink further comprising core-shell particles each comprising a core coated with a shell of linear chain hydrocarbons, wherein the core-shell particles have diameters configured to produce a predetermined reflectance of wavelength of visible light from the reflective color ink.
