ABSTRACT:
Film, fiber and coating ink manufactured by using liquid crystals comprising a combination of (a) at least one compound of each from Group (I) composed of cholesteryl alkyl carboxylate, cholesteryl alkenyl carboxylate, cholesteryl 3-chloropropionate and cholesteryl halogen, Group (II) composed of cholesteryl alkyl carbonate and cholesteryl alkenyl carbonate, and Group (III) composed of cholesteryl aromatic alkyl or alkenyl carboxylate, cholesteryl aromatic alkyl or alkenyl carbonate, cholesteryl alicyclic carboxylate and cholesteryl alicyclic dicarboxylate, and no less than six compounds in total; (b) containing 22.0 to 7.5 wt % of compounds selected from Group (I), 12.0 to 75.0 25% of compounds selected from Group (II), and 7.0 to 35.0 wt % of compounds selected from Group (III); and (c) stabilizing liquid crystal by inhibiting each other's ingredients from crystallizing. A process for coating a printed liquid crystal image with electromagnetic radiation curing resin and forming liquid crystal-protecting film by curing the coating film before defects including pinhole and breakage of film are generated. Also included is a multilayer laminated product of liquid crystal image manufactured by laminating liquid crystal images with different color temperatures to change a visible image with the ambient temperature.
