Abstract:
A pre-aligned cholesteric liquid crystal (CLC) color ink which is applied at ambient temperature for producing color images having color saturation higher and brighter colors than conventional absorptive pigment-based or dye-based inks comprising: pre-aligned CLC solid state platelets or flakes wherein the CLC molecules maintain a helical structure with a helix axis perpendicular to the surface of said platelets, a helix pitch pretuned to give the platelet the selective reflection property at a desired additive primary color (wavelength) band; and a host material in which said pre-aligned CLC platelets are suspended and the combination is applied to a substrate on which a color image is formed, said host material is formulated for its suitability to a particular image forming means and type of substrate on which the image is formed.
