▎ 摘  要

NOVELTY - The method applying (114) carbon black coating over the UV solution cast liquid crystal poly ethylene terephthalate (PET) layer. The second liquid crystal coating is applied (116) over the PET layer coated with carbon black coating and is allowed to dry. The third UV curing process is applied (118) after drying the second liquid crystal coating over the PET layer coated with carbon black coating. The roll A is punched (120) using a die, where the roll A is punched in random, specific or discreet shape and sizes, where punched roll A is scrapped using a knife at an angle, thus scraped roll A forms small particles of liquid crystals. The liquid crystal pigments are collected (122). USE - Method of obtaining liquid crystal pigments coated with carbon black coating. ADVANTAGE - The method is configured to provide a high security color shift inks with carbon based black coating, provide a high security color shift inks with graphene based black coating, provide a high security color shift inks, and provide a high security color shift inks. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method of obtaining liquid crystal pigments coated with carbon black coating. Step for applying carbon black coating (114) Step for applying second liquid crystal coating over the PET layer coated with carbon black coating (116) Step for applying third UV curing process (118) Step for punching roll A using a die (120) Step for collecting liquid crystal pigments (122)
